03A4457FFFF0FFA5FF51FF537424FEDF.taxon	etymology	Etymology. The specific name is derived from the name of Far Eastern region, where it was discovered. Treated as a noun in the nominative singular standing in apposition to the generic name.	en	Ponomarenko, Margarita G., Koshkin, Evgeny S. (2025): New species of the spring flat moths of the genera Semioscopis Hübner and Luquetia Leraut (Lepidoptera: Depressariidae) from Far East of Russia with notes on related species.

03A4457FFFF0FFA5FF51FF537424FEDF.taxon	discussion	Remarks. The new species is most similar to S. japonicella Saito, 1989 and S. steinkellneriana ([Denis et Schiffermüller], 1775) in appearance by a longitudinal black sinuous streak on the proximal part of the forewing, which outlines the discal cell distally. The study of the holotype of S. japonicella allowed to clarify the differences in the appearance and the male genitalia between the type-specimen described from Japan and S. fareastenica sp. nov. The new species can be distinguished from S. japonicella by light grey forewing with thinner sinuous streak and semi-oval arc outlining discal cell, whereas S. japonicella has brownish forewing with relatively thick sinuous streak and semi-circle arc outlining discal cell (Fig. 15). The most significant differences of the new species from S. japonicella in the male genitalia: saccular process (cuiller) shorter than width of valva in the place of its arising, socius rectangular in shape and less than half width of tegumen in distal part, aedeagus with distal part 2 times narrower than its basal part, cornutus 7 times shorter than total aedeagus length (Figs 23 – 25). S. japonicella possesses a saccular process (cuiller) almost equal to width of valva in the place of its arising; socius trapezoidal and extended distally, longer than half width of tegumen in distal part; aedeagus slightly narrowed in distal part; cornutus 4 times shorter than total aedeagus length (Figs 19 – 22). Main characters by which these two similar species can be distinguished are included in Table 2. The similarity in appearance between S. japonicella and S. fareastenica sp. nov. actually contributed to the incorrect identification of the material from the south of the Russian Far East and South Korea as S. japonicella (Lvovsky 1999; Koo et al. 2023). The illustrated male genitalia of the specimen from south of Russian Far East (Lvovsky 1999: Fig. 19, 6) are quite corresponding with those in the holotype of S. fareastenica sp. nov. and differ from the male genitalia of the holotype of S. japonicella by the characters listed above and in Table 2. The only specimen (female) from South Korea was found to be conspecific with S. fareastenica sp. nov. by the morphology of female genitalia (Koo et al. 2023: Fig. 4). Besides, the genetic distance between the same sample from South Korea and the sample from southern Far East of Russia (Amurskaya Oblast’, Blagoveshchensk) is 0.2 % on COI fragment (Fig. 52), which also indicates that they belong to the same species. Since the samples from South Korea and Far East of Russia (Amurskaya Oblast’, Blagoveshchensk) posted to the GenBank (NCBI) and BOLD System databases were erroneously identified, their sequences in molecular analysis and in Table 1 are used under specific name in quotes S. “ japonicella ”. character numbers in this table correspond to the numbers of the characters in circles in Figures 19 – 21, 23 – 25.	en	Ponomarenko, Margarita G., Koshkin, Evgeny S.

The specific name is derived from Latin word tigrinus meaning stripy or similar to animal, tiger, in transverse striations in the pattern of its skin. An adjective in the nominative singular. Feminine.	en	Ponomarenko, Margarita G., Koshkin, Evgeny S.

03A4457FFFFCFFA6FF51FAB671E9FC1F.taxon	discussion	Remarks. The described species L. tigrina sp. nov. is similar to some species from the Semioscopis (S. avellanella Hübner, S. steinkellneriana ([Den. et Schiff.]), S. japonicella Saito, S. similis Saito, S. packardella Clemens, S. merriccella Dyar, S. aurorella Dyar and S. mcdunnoughi Clarke) in appearance by some elements of forewing pattern, namely black stripe on the proximal part of discal cell and especially black arcuate stripe at end of discal cell. Also L. tigrina sp. nov. is similar to S. fareastenica sp. nov. and S. steinkellneriana by long labial palpi. Luquetia tigrina sp. nov., as Semioscopis spp., has no pecten on the antennal scape and tufts of raised scales on the forewings. The last character differs L. tigrina sp. nov. from the type species of the genus Luquetia, which cannot be said about other species of this genus, since this feature was not mentioned in their description. However, L. tigrina sp. nov. is similar to the type species of the genus Luquetia, L. lobella, by the genitalia of both sexes, which was the main reason for determining the taxonomic position of this species. Besides, the new species possesses flat, rounded and relatively wide antevaginal plate in the ostial area of the female genitalia, which is similar to that in Semioscopis merriccella Dyar (Moth Photographers Group 2024). The new species differs by unique pattern of forewing from all known species from both mentioned genera. Also, it can be identified by the saccular process (cuiller) arising exactly from the middle of the valval ventral margin, an aedeagus curved ventrally and spirally twisted in the male genitalia; and by a relatively wide, rounded antevaginal plate in the female genitalia. The related species L. lobella bears the saccular process (cuiller) arising beyond the middle of the valval ventral margin, aedeagus short, stout and slightly curved ventrally in the male genitalia; and with a very narrow, rounded antevaginal plate in the female genitalia.	en	Ponomarenko, Margarita G., Koshkin, Evgeny S.

03A4457FFFFBFFA2FF51FF1B7411FD7E.taxon	discussion	Remarks. This species was listed in the fauna of southern Far East of Russia (Lvovsky & Dubatolov 2007; Lvovsky 2008, 2016, 2019) without illustrations. The male genitalia, figured for a specimen from the Russian Far East, identified as S. japonicella (Lvovsky 1999: Fig. 19: 6), fully correspond to those of the described S. fareastenica sp. nov. The specimen, collected in Russian Far East (Amurskaya Oblast’) and in South Korea, which were posted to International NCBI and BOLD System databases as samples of S. japonicella, were found to be conspecific with S. fareastenica sp. nov. on the base of molecular analysis and morphology of female genitalia. Therefore, the distribution of this species in Russian Far East and South Korea requires confirmation.	en	Ponomarenko, Margarita G., Koshkin, Evgeny S.
