It was also recorded from Korea (Oh et al. 2018).</p><p>Host plants.</p><p>Apolygus adustus lives on broadleaf trees and bushes (Kulik 1965 a). Kulik (1974) reported it from Maackia amurensis Rupr. ( Fabaceae).</p><p>Notes.</p><p>Oh et al. (2023) mentioned that A. adustus is known from Japan, but Yasunaga (2023) did not include it to the checklist of the Japanese species, therefore, it is likely that A. adustus does not inhabit this country. Judging from the images and drawings of the genitalia structures and habitus (Josifov and Kerzhner 1972; Oh et al. 2018), the specimens from Korea are conspecific with those that are preserved at ZIN. In Russia this species was previously recorded from Amur Province, Khabarovsk and Primorskiy Territories and the south of Sakhalin Island (Kulik 1965 a; Miyamoto et al. 1994; Kerzhner 1988 b; Dubatolov et al. 2023). Here we confirm that A. adustus is distributed in Primorsky and Khabarovsk Territories, but we did not have the specimens from the Amur Territory and Sakhalin Island. Among species known from the Far East, A. adustus is most similar to A. fraxinicola in coloration (Figs 10 A – D), but the latter differs in the cuneus often with red tinge along its inner margin or mostly dark brown to black (Fig. 10 C, D), its hind femur often has the distinct brown or red bands apically, and the vesica has the long needle-shaped sclerite (Fig. 16 E).</p><p>Among the Japanese species, A. adustus is similar to A. amamicus Yasunaga, 2023 in the coloration and size (Yasunaga 2023). This species is known from females only. However, Yasunaga (2023) did not compare the new species with A. adustus, and further studies of male genitalia and molecular data are needed to confirm the status of A. amamicus .</p></div>	https://treatment.plazi.org/id/E643E79E16E25B38A63F64311C7B2DCD	Public Domain	No known copyright restrictions apply.

Records from Khabarovsk and Primorskiy Territories (Kerzhner 1972; Kulik 1974) refer to A. infamis (see Notes). This species was also recorded from Japan (Yasunaga 1992 a, 2023; ZIN).</p><p>Host plants.</p><p>Apolygus furvus was collected from Hydrangea paniculata ( Hydrangeaceae) (Kerzhner 1977, 1978, 1988 b). Yasunaga (1992 a) also recorded this species from Polygonum cuspidatum ( Polygonaceae), Actinidia polygama ( Actinidiaceae), Ligustrum obtisifolium ( Oleaceae). At least some of those records can refer to A. infamis or A. shikotan sp. nov. (see Notes).</p><p>Notes.</p><p>Kerzhner (1972) described A. furvus from the different regions of the Russian Far East (Primorskiy, Amur and Khabarovsk Territories, Sakhalin Island, Kuril Islands). He provided drawings of the vesica and parameres, however, these genital structures belonged to another species, A. infamis, which was described later from the paratypes of A. furvus (Kerzhner 1977) (see diagnosis for A. infamis). We examined the holotype of A. furvus including genitalia (Tobuty, Siretoko Peninsula, Sakhalin), and found that the specimen is teneral, and its sclerites are underdeveloped. For example, the median sclerite which is present in all species of Apolygus, is indistinct in this specimen (Fig. 16 G, H). Additionally, we could not see the needle-shaped sclerite. It is unclear whether it is absent or soft and membranous. We dissected all other males of the specimens identified as A. furvus and found that all of them have distinct median and needle-shaped sclerites. Although there is a possibility that the holotype and paratypes belong to the different species, we consider them as conspecific. There were three specimens from the Primorskiy Territory originally assigned to this species by Kerzhner (1972). Two of them from Vinogradovka and Gorno-Taezhnaya Station are females, and their identification cannot be confirmed. The third specimen from Suchan now is a holotype for Apolygus infamis (Kerzhner 1977) . However, we confirm that A. furvus lives in the Primorskiy Territory based on the specimens collected later and preserved at ZIN. The single specimen from Khabarovsk Territory originally assigned to A. furvus was also transferred to A. infamis . Apolygus furvus was recorded from a single location in Amur Province (Korsakovo). However, only females belong to this series, and we could not confirm the identification of those specimens. Kerzhner (1977) synonymised A. furvus with A. hilaris, however, later the same author treated those two species as separate (Kerzhner 1988 b). According to the original description (Horváth 1905), A. hilaris is reddish yellow, and the posterior part of corium has black marking. This fits the description of the specimens currently assigned to A. hilaris, and A. furvus has brown to black corium.</p><p>In Yasunaga (2023) the vesica of paratype was depicted and it has needle-shaped sclerite shorter than the wing-shaped sclerite as in the specimens examined by us. However, in Yasunaga (1992 a) the needle-shaped sclerite is longer than the wing-shaped sclerite, and those specimens can belong to another species. Among the voucher specimens used for the phylogenetic analyses, there is a specimen M 199, which is similar to A. furvus in coloration, and its right paramere has a long apical process. However, it has two short needle-shaped sclerites at base, and might represent a new species (Fig. 16 C, D).</p><p>Among the species known from the Russian Far East, A. furvus is most similar to A. infamis and A. shikotan sp. nov. These two species differ from A. furvus in the concave outer margin of wing-shaped sclerite (Figs 17 F, 17 G, 18 C, 18 D). Apolygus infamis also differs in the shorter wing-shaped sclerite, which is 4 × as long as wide, and A. shikotan sp. nov. differs in the apical process of its right paramere shorter than the paramere body (Fig. 19 W). Among other dark brown to black species of Apolygus, A. ater, A. furvellus, A. miyamotoanus, and A. nigricans have the needle-shaped sclerite longer than the wing-shaped sclerite, and A. ater also differs in having the dark brown femora. In A. atrobellus, A. miyamotoanus, A. nigricans and A. seonheulensis the apical process of the right paramere shorter than the paramere body, in A. miyamotoanus and A. seonheulensis the wing-shaped sclerite only 3–4 × as long as wide and in A. ater the needle-shaped sclerite is absent (Wang and Zheng 1982; Oh et al. 2018; Yasunaga 2023).</p></div>	https://treatment.plazi.org/id/0EC4BF09B9FC5EE9B49D8927164D0AB3	Public Domain	No known copyright restrictions apply.

It also inhabits Japan (Horváth 1905; Josifov and Kerzhner 1972; Yasunaga 1992 a, 2023; ZIN) and Korea (Josifov and Kerzhner 1972; Seong and Lee 2007; Oh et al. 2018).</p><p>Host plants.</p><p>Apolygus hilaris was recorded from Lonicera sp. ( Caprifoliaceae) (ZIN), Syringae amurensis ( Oleaceae) (Kerzhner 1988 a, ZIN), Syringae reticulata ( Oleaceae) (Yasunaga 1992 a), Lespedeza sp. ( Fabaceae) (Kulik 1965), Lespedeza bicolor ( Fabaceae) (Kulik 1974; Kerzhner 1988 a, 1988 b), Maackiae amurensis ( Fabaceae) (Kulik 1974).</p><p>Notes.</p><p>Apolygus syringae was described by Kerzhner (1988 a), but he mentioned that it differs from A. hilaris by the clypeus color. Yasunaga (1992 a) synonymized A. syringae with A. hilaris, but later the same author resurrected the status of this species (Yasunaga 2023) based on the shape of the right paramere, number of teeth in the wing-shaped sclerite and the antennal segment II / segment I ratio. We studied the specimens identified as A. hilaris and A. syringae preserved at ZIN, including the holotype of the latter. We compared their genital structures with the published figures, and we could not find any differences between those two species. In particular, the parameres are very similar. Most probably, the images of the parameres of those two species in Yasunaga (2023) were completed in the different projections, as the shape of the parameres of the A. syringae holotype is very similar with those of the A. hilaris specimens (Figs 9 J – M, 19 K – N). Therefore, we support the previous synonymy of A. syringae with A. hilaris . In this case we confirmed the specimen identification if we had the male genitalia available for examination. Therefore, we could only assign seven specimens from Japan and Primorsky Territory to A. hilaris . The drawings and images of vesica provided in the previous papers have the same structure of vesica as in the specimens examined by us (Josifov and Kerzhner 1972 – Korea; Kerzhner 1977, 1988 a – Russian Far East; Yasunaga 1992 a, 2023 – Japan; Seong and Lee 2007 – Korea).</p><p>Apolygus hilaris is similar to a number of other species externally. Among the specimens found in the Russian Far East, A. hilaris is most similar with A. subhilaris, but the latter differs in the clypeus mostly pale and dark brown to black only apically (Fig. 15 L) and its vesica lacks needle-shaped sclerite (Fig. 17 J). Apolygus hilaris is similar with the pale representatives of A. furvus externally, but A. furvus differs in the apical process of the right paramere subequal to the paramere body (Fig. 19 E, G), and the long wing-shaped sclerite in vesica, which is 5–7 × as long as wide, and longer than the needle-shaped sclerite (Fig. 16 K). Apolygus hilaris can be confused with A. gotorum, but the latter differs in the clypeus mostly pale brown with dark brown to black apex (Fig. 15 D) and the needle-shaped sclerite only slightly surpassing wing-shaped sclerite (Fig. 16 I).</p></div>	https://treatment.plazi.org/id/61F87C94DE9153A5B3347D8DFD525997	Public Domain	No known copyright restrictions apply.

Records from Kuril Islands by Kerzhner (1977, 1978) refer to A. shikotan sp. nov. This species was also recorded from Korea (Seong and Lee 2007; Oh et al. 2018) and Japan (Yasunaga 2023). However, at least some of the specimens collected in Japan belong to A. shikotan sp. nov. (see Notes), and the male genitalia of the specimens from Korea were not published.</p><p>Host plants.</p><p>Kerzhner (1988 b) mentioned that Apolygus infamis was collected from Phyllodendron amurense Rupr. and Phyllodendron sachalinense (Fr. Schmidt) Sarg. ( Araceae), but this information is absent on the labels currently assigned to this species and can be erroneous. Apparently, the record from Phyllodendron sachalinense refers to Apolygus shikotan sp. nov., because Kerzhner (1978) mentioned that the specimens from the type locality of this species (Malokurilskoe, Shikotan Island) were collected from this plant.</p><p>Notes.</p><p>Apolygus infamis was described from the paratypes of A. furvus by Kerzhner (1977). We found that in the type series there are at least two species from Shikotan Island which differ in the shape of the right paramere and wing-shaped sclerite. We describe the second species as new to science, Apolygus shikotan sp. nov. The records of A. infamis of Kerzhner and Marusik (1997) and Kanyukova and Marusik (2006) from Iturup, Kunashir and Shikotan Islands might also refer to A. shikotan sp. nov. Therefore, we could reliably assign only two specimens to A. infamis . The drawing of vesica in Kerzhner (1988 b) is more similar to A. shikotan sp. nov. The genitalia illustrated in Yasunaga (2023) are also more similar to A. shikotan sp. nov., and the record of A. infamis from Japan can be erroneous. Seong and Lee (2007) and Oh et al. (2018) recorded A. infamis from Korea, however, they did not provide illustrations of male genitalia of this species, therefore, the distribution of this species in Korea cannot be confirmed.</p><p>Among the species known from the Russian Far East, Apolygus infamis is similar to A. furvus and A. shikotan sp. nov., but those two species differ in the wing-shaped sclerite, which is ca. 0.75 × as long as ventral sclerite (Figs 16 G, 16 K, 17 F). Apolygus shikotan sp. nov. also differs in the apical process of the right paramere subequal to the half of the paramere body (Fig. 19 W). Among the black congeners, A. atrobellus, A. miyamotoanus, A. nigricans, and A. seonheulensis differ from A. infamis in the apical process of the right paramere shorter than the paramere body (Wang and Zheng 1982; Oh et al. 2018; Yasunaga 2023). Apolygus atrobellus can be also differentiated in the absence of the needle-shaped sclerite. Among the species with the elongate apical process of the right paramere, Apolygus ater differs in the femora mostly dark brown, and Apolygus furvellus differs in the longer wing-shaped sclerite, ca. 7–8 × as long as wide (Yasunaga 2023). Apolygus sinicus also has dark coloration but differs in the presence of Y-shaped sclerite on scutellum (Zheng and Wang 1983).</p></div>	https://treatment.plazi.org/id/3C130D67C7495BEC96A47A030686CB24	Public Domain	No known copyright restrictions apply.

This species is known from the Russian Far East, i. e. Amur, Khabarovsk, Primorsky Territories (Kerzhner 1988 b; Vinokurov et al. 2010) and East Asia, i. e.

The drawing of vesica in the key to the Heteroptera of the European part of the USSR (Kerzhner and Jaczewski 1964) corresponds to the European form. Those groups can represent two separate species; however, we did not find any differences in the shape of the parameres and habitus between them, and the molecular data were insufficient to resolve this problem. More specimens from those groups and nuclear markers should be included in the analysis. Therefore, we refrain from any taxonomic decisions pending additional molecular data. Apolygus limbatus is most similar to A. maackiae in coloration, but the latter differs in the apex of cuneus dark brown to black, yellow outer margin of embolium and yellow legs without reddish tinge. Additionally, in A. maackiae wing-shaped sclerite is absent and its ventral sclerite has needle-shaped outgrowth (Fig. 18 G, H).</p></div>	https://treatment.plazi.org/id/C229EB1FAE605FC89A22E14307C9B375	Public Domain	No known copyright restrictions apply.

We describe the second species as new to science, A. shikotan sp. nov., because it does not fit a description of any other species known from this genus. There are only a few species with dark brown to black color of hemelytron without any stripes or markings on clavus and corium, i. e., Apolygus ater, A. atrobellus, A. furvellus, A. furvus, A. infamis, A. miyamotoanus, A. nigricans, A. rubriceps, and A. seonheulensis . In A. ater, A. furvellus, A. furvus, and A. infamis the apical process of right paramere is subequal to the paramere body (Fig. 19 E – H, O, P). In Apolygus atrobellus, A. furvellus, A. furvus, A. miyamotoanus, and A. nigricans sublateral sclerite diameter shorter than the secondary gonopore (Fig. 16 K). Apolygus atrobellus differs in the absence of the needle-shaped sclerite, and in A. seonheulensis the needle-shaped sclerite does not surpass the secondary gonopore. In all those species, except for A. infamis and A. seonheulensis, the outer margin of wing-shaped sclerite is straight. Apolygus infamis, A. nigricans and A. seonheulensis additionally differ in the wing-shaped sclerite short, not surpassing the sublateral sclerite (Wang and Zheng 1982; Yasunaga 1992 a; Oh et al. 2018; Yasunaga 2023).</p></div>	https://treatment.plazi.org/id/565AF38C49955936BA9E3BFD163D352E	Public Domain	No known copyright restrictions apply.

It was recorded from the Caucasus but was not recorded from Iran (Zamani and Hosseini 2020). In Central Asia A. spinolae was recorded from Kazakhstan, Kyrgyzstan, Uzbekistan (Kerzhner and Josifov 1999). It is also abundant in China (Kerzhner and Jaczewski 1999; Zamani and Hosseini 2020; Zhang et al. 2020; Lu et al. 2024). The species is also known from Canada and the USA (Kelton 1971) and can be invasive.</p><p>Host plants.</p><p>Polyphagous. In particular, its specimens were collected from Thermopsis sp., Thermopsis lupinoides, Lespedeza sp. ( Fabaceae), Artemisia spp., Tanacetum sp. ( Asteraceae), Rosaceae, Urtica sp. ( Urticaceae) (Kelton 1971; Kerzhner 1978, 1988 a; Yasunaga 1992 a). The species is considered as a pest of many plants, e. g., Camellia sinensis (tea plant), cotton, vegetables, fruits (Yasunaga 1992 a; Zhang et al. 2020; Lu et al. 2024). It was also recorded as omnivorous (Lu et al. 2024).</p><p>Notes.</p><p>Meyer-Dür (1841) described the new species Capsus spinolae Meyer-Dür, 1841, and the same author (Meyer-Dür 1843) described Capsus lucorum Meyer-Dür 1843, both from Switzerland. He noted that C. lucorum is similar to C. spinolae but differs in the brighter coloration, absence of marking above cuneus and darker membrane. There were several specimens in the type series of the species described by Meyer-Dür (1941, 1943). Kerzhner (1996) designated lectotypes for both species, female in each case, preserved at the American Museum of Natural History. We requested digital images of the lectotypes, however, at this moment they are lost, and the paralectotypes of both species are very similar to each other, having uniformly yellow dorsum and clypeus, which also corresponds to the original description. However, paralectotype of A. spinolae have slightly darkened apex of cuneus (Fig. 14 B, F), although it was not mentioned in the original description.</p><p>In the consequent keys those two species were differentiated using the presence and absence of the marking on cuneus apically (Wagner and Weber 1964; Wagner 1974; Kerzhner and Jaczewski 1964; Yasunaga 1992 a; Vinokurov and Kanyukova 1995; Seong and Lee 2007). Kerzhner (1988 a) and Vinokurov and Kanyukova (1995) also mentioned that two species can be differentiated in the mostly darkened or mostly pale clypeus in A. lucorum and A. spinolae respectively. Stål (1858) described a new species Deraeocoris nigro-nasutus from Siberia (Irkutsk), but he did not compare it with A. lucorum and A. spinolae . Lygus (Neolygus) malaisei was described by Lindberg (1925) from Kamchatka Peninsula, but he did not compare it with any species placed in Apolygus by that time. Kerzhner (1988 a) described Lygocoris (Apolygus) nigrovirens from the Russian Far East and he mentioned that all five species were very similar to each other and differed in the coloration. In particular, A. nigrovirens differed from A. lucorum and A. spinolae in the dark markings on clavus and larger marking on the apex of cuneus. In A. nigronasutus the outer margin of corium was black and clypeus was mostly black, the pronotum, scutellum and hemelytron were generally paler, and tarsal segment III was entirely dark, whereas in A. nigrovirens the outer margin of corium was pale, the clypeus was mostly pale, the pronotum, scutellum and hemelytron were darker, and half of tarsal segment III was dark. Apolygus malaisei was darker than A. nigrovirens, but there were specimens assigned to both species which were very similar in coloration. He did not provide any characters in genitalic structures which can be used for the species differentiation. Yasunaga and Yasunaga (2000) mentioned that A. nigronasutus has the needle-shaped sclerite and they did not provide the illustration or any literature reference. We consider this a mistake, because Kerzhner (1988 a) did not mention this character while comparing it with A. nigrovirens, and he noted that he could not find any differences in male genitalia in all five species. We also did not find any needle-shaped sclerite in the specimens identified as A. nigronasutus in the ZIN collection. Examination of the syntypes of this species cannot provide any additional information on the male genitalia structures, because they are females (Stål, 1858; Kerzhner and Jachewski, 1999). The characters in coloration were used in the keys of Kerzhner (1988 b) and Vinokurov and Kanyukova (1995). Yasunaga (1992 b), Seong and Lee (2007) and Kim and Jung (2016) additionally used labium length to differentiate A. spinolae and A. nigrovirens . According to Yasunaga (1992 b) and Seong and Lee (2007), the labium reaches hind coxae in the former and does not reach them in the latter. However, in the key of Kim and Jung (2016) the labium reaches hind coxae in A. nigrovirens, whereas it is shorter in A. spinolae . We examined the large collection preserved at ZIN and dissected males belonging to numerous series of each species. We found that the coloration is very variable in all five species, and it is impossible to split them into the discrete morphs based on the characters mentioned by the previous authors. In particular, it was not possible to find the discrete states for the coloration of cuneus, which can be entirely green (Figs S 12 O, S 15 C, S 16 C, I, O, U, S 17 C, I, U), slightly darkened apically (Figs S 12 V, S 14 J, P, S 17 O, 18 C, I) or having distinct dark brown marking apically of various size (Figs S 12 C, I, S 13 C, H, N, T, S 14 D, W, S 18 O). The same is true for the color of clypeus (Figs S 12 – S 18). Additionally, the marking on clypeus cannot be used for the discrimination of A. lucorum from A. spinolae, because the representatives of type series of both species have entirely pale clypeus (Fig. 14 B, F). The length of the labium cannot be used to separate A. nigrovirens and A. spinolae, because its position with respect to the middle and hind femora depends on the position of the head. Kerzhner (1988 a) did not mention this character in the original description, and it is unclear how Seong and Lee (2006) and Kim and Jung (2016) associated the labium length with the characters provided in the original description.</p><p>Jung et al. (2011) and Kim and Jung (2018 a) differentiated A. lucorum, A. nigrovirens, A. spinolae and A. watajii in the shape of sclerites in vesica. However, in those two papers the authors use different color criteria to separate the species and the characters in the sclerites corresponding to the color morphs are also different. In particular, according to Jung et al. (2011) in A. lucorum clypeus is mostly dark and the wing-shaped sclerite has teeth, whereas in A. nigrovirens and A. spinolae the clypeus is mostly pale and the wing-shaped sclerite is smooth. It is unclear from this work how they differentiated A. nigrovirens and A. spinolae from each other. According to Kim and Jung (2018 a), A. lucorum and A. spinolae differ in the following characters: in the former, the apex of cuneus is pale, the wing-shaped sclerite is broad and the sublateral sclerite is present, whereas in the latter the apex of cuneus is darkened, the wing-shaped sclerite is slender and the sublateral sclerite is absent</p><p>The color morphs associated with the species names in Jung et al. (2011) were erroneous, because A. lucorum and A. spinolae do not differ in the clypeus color, which is confirmed by the images of the paralectotypes (Fig. 14 B, F) and this character has not been mentioned in the original description. After examination of genitalia belonging to the different color morphs, we could not find any specimen having the wing-shaped sclerite without teeth, however, we agree that the teeth size is variable (Figs S 12 – S 18). Additionally, the teeth are most obvious when the vesica is illustrated in the right lateral view, whereas in Jung et al. (2011) the image illustrating the smooth wing-shaped sclerite shows the vesica rotated towards the dorsal view (fig. 3 F in Jung et al. 2011). We also imaged the vesica in the same rotated view and found that the teeth are less obvious in this position, even if they are distinct in right lateral view (Figs S 12 T, S 14 B, O). This character was also mentioned in Yasunaga (1992 a) in the comparison of A. spinolae with A. lucorum, but he did not mention it in the key for Japanese Apolygus species published the same year (Yasunaga 1992 b).</p><p>Although some authors used the shape of wing shaped sclerite to separate A. lucorum and A. spinolae, they did not provide any particular ratio, using the descriptive terms “ broad ” and “ slender ” (Yasunaga 1992; Kim and Jung 2019). Examination of the specimens from the large part of the Palearctic showed that the shape of this sclerite is variable and does not correspond to the color morphs (Figs S 12 – S 18). Sublateral sclerite also vary and can be absent (e. g., Fig. S 12 B, H, U), pale (mostly membranous) (e. g., Figs S 13 M, 16 B, T) and distinct (e. g., Figs S 13 B, S 16 I, N). The distinct sublateral sclerite was usually present in the specimens with pale apex of cuneus and without additional markings on dorsum ( A. lucorum) (e. g., Figs S 15 B, S 16 H, S 17 H), but the representatives of the same color morph sometimes do not have this sclerite (Fig. S 17 N) and it is also present in other color morphs (Fig. S 13 B). The presence and absence of this sclerite also does not correspond to the clades in the phylogenetic trees. Additionally, the sublateral sclerite can be absent and present within A. watajii . It is depicted in the images provided by Seong and Lee (2007) and in the specimens examined by us (Fig. 17 L, M), however, Kim and Jung (2019) reported its absence in the same species but did not comment on the previous work. In those two papers and the specimens examined by us the shape of the wing-shaped sclerite is the same for A. watajii, and it is very likely that all those specimens belong to the same species.</p><p>In the work of Kim and Jung (2019) the sequences of A. nigrovirens from Jung et al. (2011) were not included to the analysis without any explanation and it is unclear how they differentiate this species from A. lucorum and A. spinolae . Additionally, the specimen of A. spinolae in the image provided in Kim and Jung (2019), has a dark marking on clavus. According to the original description and the key to Far East (Kerzhner 1988 a, 1988 a), A. nigrovirens had this marking, whereas A. spinolae did not. Kim and Jung (2019) did not comment on this character.</p><p>Overall, we could not find any discrete characters in male genitalia in species group, comprising A. lucorum, A. malaisei, A. nigronasutus, A. nigrovirens, and A. spinolae . Both molecular and morphological characters indicate that the specimens previously identified as those five species represent a single polymorphic species. The examination of the previous literature shows that the criteria on how the researchers assign the specimens to those species are different in the different studies, and we should rely on the original descriptions and types to treat those species. The original description and the paralectotypes show only a single difference between A. lucorum and A. spinolae, which is the coloration of the apex of cuneus. The examination of the numerous specimens from the most part of the Palearctic shows that this character is variable and cannot be considered as discrete (Figs S 12 – S 18). We could not examine the lectotypes and based on the original descriptions they should be mostly green with darkened membrane and the tarsi dark brown to black apically (Meyer-Dür 1941, 1943). The examination and dissection of those specimens will not provide any additional information, because they are females, and the differences in the female genitalia have never been reported for those two species, and we could not find them as well. The differences of the sclerite shapes are also not discrete and do not correspond to the color morphs.</p><p>Other species which have similar or the same male genitalia as A. spinolae and green or yellow coloration are Apolygus atrosignatus, A. halophilus, A. nepius, A. olivarius, A. rhamnicola, and A. watajii (Wagner and Weber 1964; Yasunaga and Yasunaga 2000; Yasunaga 2023). All those species were previously separated using coloration, which is unreliable, considering the color variation range in A. spinolae . Among them A. watajii can be separated from A. spinolae in the wing-shaped sclerite 2–3 × as long as wide, and A. nepius has wide ventral sclerite (Yasunaga and Yasunaga 2000) (Fig. 17 L). According to Yasunaga (2023) A. halophilus has the antennal segment III distinctly shorter than the head width whereas in A. spinolae it is as long as the head width (Yasunaga 2023). According to Yasunaga and Yasunaga (2000) A. atrosignatus, can be differentiated from A. spinolae in the longer antennal segment III. Apolygus olivarius differs from A. lucorum in the antennal segments II / IV ratio (Yasunaga 2023). However, antennal segments III and IV are sometimes shrunken, and it is impossible to measure their length correctly. Although A. rhamnicola is an European species, very little is known about its morphology. According to Wagner and Weber (1964), it differs from A. lucorum and A. spinolae in the presence of the dark markings at the bases of spines on tibiae, however, many specimens of A. spinolae also have them, but those specimens usually have darker coloration of dorsum (e. g., A. nigrovirens, A. nigronasutus, A. malaisei color morph). We dissected the specimen from the ZIN collection which was identified as A. rhamnicola with the coloration fitting the description of this species. The parameres and vesica are very similar to A. spinolae . The dissected specimen has a distinct sublateral sclerite with three rows of spines. However, this condition also occurs in the specimens of A. spinolae without markings at the base of the tibial spines. Therefore, we consider the status of A. rhamnicola as doubtful, and it should be tested using the nuclear markers.</p></div>	https://treatment.plazi.org/id/A47CF3C0B1E35703ABC5097668878ECE	Public Domain	No known copyright restrictions apply.

There are several species which have similar coloration and illustrations of vesica were not published for them and those three specimens can belong to one of them, i. e., Apolygus angustus (Zheng &amp; Wang, 1983), Apolygus kosempoensis (Poppius, 1915), Apolygus myittae (Distant, 1904), Apolygus triangulus (Zheng &amp; Wang, 1983), Apolygus umbratus (Poppius, 1914), or can represent a new species.

Those differences can represent the intraspecific variation. We examined the male genitalia of all the series preserved at ZIN, including those collected in Japan and Korea, and found that all of them have wing-shaped sclerite more sinuate (more notched), similar to A. habilis, and we did not find any noticeable variation in the shape of lateral sclerites or parameres.
