Orthotylus (Pinocapsus) kmenti Çerçi & Koçak

sp. nov.

Orthotylus (Pinocapsus) kmenti Çerçi & Koçak sp. n.

( Fig 7–9 View FIG View FIG View FIG )

Material examined: HOLOTYPE: 1 ♂, Turkey: Karaman, Sertavul Geçidi , 25.06.2019, B. Çerçi leg. & det., glued on a cardboard with the male genitalia glued on the same cardboard, labels as follows: “ Orthotylus (Pinocapsus) kmenti sp. n. / B. Çerçi det. 2019/ Karaman, Sertavul Geçidi, 25.06.2019 [white printed label]” ( LEMT).

COLLECTING CIRCUMSTANCES: The holotype was collected with light trap at the altitude of 1800 m.

ETYMOLOGY: The new species is named after Petr Kment, who is a specialist of Heteropteran taxonomy, with a particular interest in systematics of Pentatomoidea. He never spares the smallest chance of helping his colleagues, and the first author is very thankful to him for his endless help, for which reason we are very happy to name this new species after him.

DIAGNOSIS: Size small, 3.0 mm. General coloration black, immaculate. Setae covering dorsum uniform, long, thick, black and erected. Antennae light brown, immaculate. Head vertical, ocular index 1.9, eyes entirely outside anterior margin of pronotum. Pronotum strongly trapezoid, posterior margin 3.4× as wide as anterior margin, 0.4× as long as width of posterior margin. Hemelytra subparallel sided. Legs yellow coloured. Right paramere with two processes, one of which apically serrate, body of left paramere broad, rectangular, with three processes, one of apical processes serrate. Vesical sclerites unequal in size, one is shorter and stick-like, other one is longer and thicker, bent sideward apically and with two longitudinal sulci preapically.

Description of male ( Fig. 8 View FIG ):

COLORATION: General coloration black, immaculate. Antennae light brown coloured, third and fourth segments only slightly paled. Head black and shiny, along posterior margin slightly embrowned. Pronotum and scutellum unicolorously black and shiny. Hemelytra black, immaculate. Membrane fuscous, veins dark coloured. Legs pale coloured. Abdomen unicolorously black coloured.

VESTITURE: General vestiture simple, long, black and erected. First antennal segment covered with thick, black and semi-erected setae, second antennal segment with short, black and semi-erected setae and short, pale and adpressed setae, third and fourth segment covered with adpressed and semi-erected pale setae, semi-erected ones longer than the adpressed ones. Head covered with long, thick and black setae. Pronotum with long, thick and black erected and semi-erected setae. Hemelytra covered with long, thick and black erected or semi-erected setae. Tibiae covered with short and black adpressed setae and with thick black spines that do not arise from black dots.

STRUCTURE: Size 3 mm. Oblong oval, 3.3× as long as width of posterior margin of pronotum. Antennae medium sized, 0.55× as long as the total length, first antennal segment 0.7× as long as width of vertex, second antennal segment 3.4× as long as the first one, 0.8× as long as width of posterior margin of pronotum and as long as width of diatone, third antennal segment 0.7× as long as second antennal segment and 1.8× as long as fourth segment. Head vertical, 2.3× as wide as long, ocular index 1.9, eyes entirely outside anterior margin of the pronotum. Pronotum strongly trapezoid, posterior margin 3.4× as wide as anterior margin, 0.4× as long as width of posterior margin. Hemelytra almost parallel sided, only vaguely narrowing towards distal. Legs short, posterior femur 0.5× as long as posterior tibia and posterior tibia 1.4× as long as posterior margin of pronotum. Posterior margin of pygophore wave like with two depressions and protrusion between them, vesica with two sclerotized processes, one thin and simple, other one thick and complicated, twisted preapically, two sulci along this twist, and bent apically towards its side ( Figs. 9G–J View FIG ). Left paramere with basal process and two apical processes, one apical processes serrate, other one bare ( Figs. 9A–C View FIG ). Right paramere with broad disc, basal process and distal process, distal one apically serrate and strongly bent inwards, basal one simple ( Figs. 9D–F View FIG ).

Possible additional specimen: Figure 7 View FIG shows a specimen of Orthotylus that was found together with O. (P.) kmenti Çerçi & Koçak sp. n. Since we were not able to collect this specimen, its identity remains speculative. We believe that this specimen belongs to the new species described here, due to its very similar structure, uniform black setae and immaculate dorsum. The obvious colour difference between this specimen and the holotype of O. (P.) kmenti Çerçi & Koçak sp. n. is interesting and rises thoughts whether it is a teneral specimen or a colour variation. Still, it is worth mentioning that yellowish tinge is already known in some species of the subgenus Pinocapsus (S. Pagola-Carte pers. comm.).

DIFFERENTIAL DIAGNOSIS: The new species is included in the subgenus Pinocapsus Southwood, 1953 because of the close resemblance of the paramere shape of the other known species of this subgenus, especially to O. (P.) thaleia Linnavuori, 1999 and O. (P.) olympicus Matocq, Pagola-Carte & Pluot-Sigwalt, 2018 , and the presence of two simple, unbranched and unarmed sclerotized processes of vesica. This subgenus consists of 8 species, of which 6 species are known to occur in the Western Palaearctic Region ( Aukema 2020). Among other species, the new species is most similar to O. (P.) olympicus with respect to darker coloration and somewhat similar structure of parameres, but the new species differs from this species by smaller size (males 5.2–5.6 mm in olympicus ), general coloration darker (greyish in olympicus ), vestiture uniform (double pubescence in olympicus ), right paramere with two processes (three in olympicus ), body of left paramere broad (slender in olympicus ) and dissimilar sclerotized processes of vesica ( Fig. 17 View FIG ) ( Matocq et al. 2018). The new species can also be confused with Orthotylus (P.) thaleia and O. (P.) fuscescens (Kirshbaum, 1856) because of their olive-green coloration tending to grey but it also differs from these species by smaller size, black coloration, simple black vestiture and dissimilar vesical processes ( Wagner 1974, Linnavuori 1999). Although O. (P.) cupressi Reuter, 1883 is quite a different species, it is necessary to mention differences between the new species and O. (P.) cupressi as it was widely recorded from Turkey ( Önder et al. 2006). The new species differs from O. (P.) cupressi by smaller size (3.3–3.9 mm in cupressi ), different coloration (green in cupressi ), black vestiture (pale in cupressi ) and dissimilar male genitalia ( Figs. 11, 20–21 View FIG for cupressi ). The new species differs from rest of the known species of its subgenus distributing in Western Mediterranean [ O. (P.) gemmae Gessé & Goula, 2003 and O. (P.) callistris Lindberg, 1940) and Central Asia [ O. (P.) alashanensis Tian & Nonnaizab, 1999 and O. (P.) sabinae Tian & Nonnaizab, 1999 ) by small size, uniform black vestiture, general coloration black and the unique shape of parameres and vesical processes ( Figs. 10–33 View FIG ). Table 2 View TABLE 2 summarizes differential diagnostic features between East Mediterranean species of Orthotylus (Pinocapsus) and the new species.
