6F72C74CFF81FF9FFF5BF956099811D7.taxon	diagnosis	This species group of the genus Nemophora Hoffmannsegg, 1798, is identified by a combination of the following characters: 1. Basal part of forewing (one quarter to one third of FWL) light yellow to glossy golden, sharply contrasting with the darker (usually bronze to coppery bronze) colouration of the medial and apical parts of the forewing. 2. Characteristic pattern of two longitudinal silver stripes starting at the forewing base and forming a <- shaped figure, which in some species is reduced to two short stripes parallel to the costa. 3. Frons glossy silver or covered by translucent scales. 4. Vertex pale yellow to ochreous. 5. Male PLB very short (0.3 ‒ 0.8 × vertical eye diameter). 6. Male compound eyes strongly enlarged, closely approaching or touching each other posteriorly. 7. Base of proboscis thickened with light ochreous to bronze or coppery scales often forming a conspicuous brush.	en	Kozlov, Mikhail V.

6F72C74CFF81FF9FFF5BF956099811D7.taxon	description	The profusella species group may be remotely related to the kalshoveni species group, which includes seven Nemophora species from the islands of Indonesia and Papua New Guinea (Kozlov 2016 b). This assumption is supported by two characters. First, the proboscis of kalshoveni - group species is densely covered with raised dark brown to black scales and appears unusually thick (compare with character no. 7 above). Second, the colouration of the male antenna in both groups often differs between the basal, medial and apical parts of the flagellum. The profusella species group may eventually be subdivided, as it includes species that differ markedly in the morphology of the female antenna. Females of four species (N. meeki, N. hippophylax, N. profusella and N. sulphurea) possess a characteristic basal scale-thickening on the flagellum, whereas females of another four species (N. ochrodorsella, N. chrysodonta, N. plutodotis and N. vasilyi) lack raised scales in the basal part of the flagellum. Thus, sexual dimorphism in antennal structure is present in only some species. However, the absence of information on female antennal morphology in 13 species currently precludes formal subdivision of the profusella group. Therefore, the sequence of species in both the checklist and the main text follows that of the key below.	en	Kozlov, Mikhail V.

6F72C74CFF84FF9EFF5BF91D09051419.taxon	discussion	Comments. Although Walsingham clearly labelled the holotype as a new species from a new genus, he never published descriptions of either the species or the genus. No differences in thoracic dorsum colour were found between males and females of the four species of the profusella group for which both sexes are known; hence, there is probably no sexual dimorphism in this trait. A female with ochreous dorsum could therefore only be associated with a male sharing this feature. Males of only two species, N. sulawesiensis (Fig. 25) and N. plutodotis (Fig. 27, 28), have dull yellow spots on glossy dorsum, but their external appearance greatly differs from N. ochrodorsella. Therefore, this female is described as a new species rather than being associated with any of the eleven profusella - group species known from males only.	en	Kozlov, Mikhail V.

6F72C74CFF8BFF96FF5BFF210F221649.taxon	diagnosis	Diagnosis. Nemophora profusella differs from all other species of the profusella group by the combination of a uniformly dark hindwing, a dark-ringed base of the male antenna and the presence of a dark spot (sometimes very large, or several spots) at the outer forewing margin. It differs from the externally similar N. hippophylax (males of which are unknown) by the light grey colour of the hindwing fringe.	en	Kozlov, Mikhail V.

6F72C74CFF8BFF96FF5BFF210F221649.taxon	discussion	Comments. Walker (1866) indicated the number of specimens he studied by placing letters in front of the collecting locality, with ‘ a. ’ referring to a single specimen. This letter, for example, appears in the description of Nemotois tristrigella on the previous page of the same work in which N. profusella was described. However, no such letter appears in front of “ New Guinea ” in reference to N. profusella. Thus, Walker (1866) did not explicitly indicate that the description of N. profusella was based on a single specimen. Therefore, I designate the only surviving type as the lectotype rather than the holotype. This lectotype was presumably collected by A. R. Wallace in 1858 at the western side of Papua Island (Waigeo, Salawati or Manokwari; www. papua-insects. nl). The identity of N. profusella had long been confusing, particularly because Walker (1866, p. 1816) described the male antenna as “ silvery white, cupreous at the base ”. Consistently, Meyrick (1930, p. 571) noted that in N. profusella “ the antennae are not ringed ”. However, the lectotype designated from the NHM collection has ringed antennae. If we assume that “ the base ”, as defined by Walker (1866), extended to one-third of the flagellum, then this trait, in combination with the forewing pattern, fits N. neuguineae rather than N. profusella in its current understanding. Diakonoff (1955, p. 144) wrote that he had seen “ fine photographs of the genitalia of the type specimen (male) in the British Museum ” provided by J. D. Bradley. However, the abdomen of the specimen designated as the lectotype had long been missing, and there is no record of a genitalia slide made from the lectotype of N. profusella. Some genitalia glued to a card without a corresponding number are kept next to the lectotype in the NHM collection (D. Lees, personal communication), but it remains unknown whether these genitalia belong to the lectotype. Thus, A. Diakonoff studied a specimen of uncertain identity, which was selected by J. D. Bradley among specimens kept in the NHM collection under the name N. profusella. Genitalia slide 1749 was prepared by J. D. Bradley in April 1949 from a specimen collected in Andai by W. Doherty in 1892 (specimen no. 41731). Based on external characters, I tentatively identified this specimen as N. neuguineae. However, it differs from the type series of N. neuguineae (described below) by having a shorter vinculum (2.6 vs. 3.4 ‒ 3.6 × length of valva in N. neuguineae) and a different shape of the apical processes of the phallus. To be cautious, I have placed this specimen and two others from the same series in other material of N. neuguineae instead of including them in the type series. The record of N. profusella from Kokoda (Diakonoff 1955), based on an NHM specimen identified by A. Diakonoff in 1950, actually belongs to N. cheesmanae (see below). The latter species has complete yellow band, which contradicts the original description and Diakonoff’s (1955) key, where N. profusella is defined by a costal yellow spot. Analysis of ten characters (FWL, WLR, extent of basal yellow field, position of internal margin of yellow band of fascia and its extent — both along costa and perpendicular to it, shape of yellow band or spot, extent and shape of dark brown bands on both sides of yellow band of fascia, and number of dark spots at outer wing margin) in 16 male specimens tentatively identified as N. profusella revealed that all differ from the lectotype by a greater extent of yellow colour in forewing fascia. While the yellow spot in the lectotype is only 0.35 × forewing width, it varied from 0.50 to 1.0 × forewing width across the studied males. Thus, there remains a possibility that specimens other than the lectotype belong to a distinct yet undescribed species. However, the absence of other differences in external traits, combined with substantial variation in forewing pattern of specimens originating from the same locality (Figs. 11 ‒ 15), makes the description of a new species premature.	en	Kozlov, Mikhail V.

6F72C74CFF93FF8FFF5BFF2108491101.taxon	diagnosis	Diagnosis. Nemophora cupriantennella differs from all species of the profusella group by the bifurcate ventral process at the tip of the phallus. It resembles N. sulawesiensis (Fig. 25) in the dark coppery colour of the entire male antenna, but differs from that species by the male compound eyes not touching each other posteriorly and by a relatively narrow forewing (WLR 0.35 ‒ 0.37). From the closely related N. cheesmanae (Figs. 30, 31), it differs by the relatively wide yellow band of fascia, short silver stripes in the yellow basal field of the forewing, and a very short epiphysis located at 0.45 of tibia.	en	Kozlov, Mikhail V.

6F72C74CFFA1FFB8FF5BFDF00D7A11C9.taxon	diagnosis	Diagnosis. Nemophora cheesmanae differs from all species of the profusella group by the presence of both a wide indentation and a prominent medial ridge at the tip of the tegumen in the male genitalia. It differs from the closely related N. cupriantennella (Fig. 22) by the relatively narrow yellow band of fascia, long silver stripes in the basal part of the forewing, and a long epiphysis located at 0.6 of the tibia; and from N. neuguineae by the complete yellow band in the forewing bordered by narrow dark bands and a longer male antenna. From both these species, N. cheesmanae also differs by the white, dark-ringed basal third of the male flagellum.	en	Kozlov, Mikhail V.
