Coptotriche brevissima Zhang, Sun & Li, 2025, sp. nov.

Coptotriche brevissima sp. nov. urn:lsid:zoobank.org:act: 71A27452-A67B-4887-9FFB-835A8E541C1D (Figs 3, 7, 9) Type material. Holotype ♂, CHINA, Sichuan: Baliping, Anzihe, 1706 m, 24.vi.2016, leg. K.J. Teng and X.F. Yang, gen. slide No. SH21319. Paratype 1♀, same data as holotype, gen. slide No. SH21318. Diagnosis. The new species is similar to Coptotriche longispicula (Puplesis, 1988) in the male genitalia. It can be distinguished by the forewing without a tornal spot; the vinculum extended anteriorly in short triangle and the tulip-shaped part of the phallus uniformly wide in the male genitalia. In C. longispicula, the forewing has a tornal spot formed by dark brown scales; the vinculum extends into an elongate club anteriorly and the tulip-shaped part of the phallus is abruptly constricted to a small triangularly-shaped apex in the male genitalia (Diškus 1998: 30). Description. Adult (Fig. 3). Male wingspan 10.5 mm. Head. Frons cream; pecten pale yellow; frontal tuft straw yellow. Proboscis yellowish brown except yellow in basal 1/5. Labial palpus pale ochreous yellow. Antenna 0.64 × length of forewing; scape and flagellum whitish yellow. Collar ochreous yellow. Thorax. Mesonotum yellow; tegula yellowish brown. Forewing straw yellow, with black scales denser along costal margin; fringe grey-yellow, tinged with yellow. Hindwing greyish yellow; fringe yellow. Foreleg yellow ventrally, dark brown except coxa yellow dorsally; midleg yellow ventrally, bronzy dorsally except femur yellow; hindleg pale straw yellow. Epiphysis bronzy, at basal 2/5 of tibia, reaching apex of tibia. Abdomen. Yellow, with brown scales. Male genitalia (Fig. 7). Uncus with lateral lobes obtusely rounded at apex; excavation between uncus lobes broadly arched anteriorly. Socii membranous, spinous. Tegumen almost uniformly wide medially; lateral arm narrowed anteriorly, sclerotized on inner margin. Valva parallel sided from base to 1/2, widened beyond middle, thereafter narrowed to obtusely rounded apex, setose densely; costal margin slightly concave at middle; ventral margin convex beyond middle. Transtilla (Fig. 7a) slender; sublateral processes long, 0.44 × length of transtilla, slightly swollen distally. Vinculum (Fig. 7b) with ventral plate subtriangular, short, narrowed to rounded anterior margin. Phallus 1.2 × length of capsule; tulip-shaped part uniformly wide, with two rows of spines from its basal 1/5 to 5/7 laterally. Female genitalia (Fig. 9). Main ovipositor lobes subtrapezoid; second pair of ovipositor lobes fusiform. Inner prela short and wide, closely approaching each other anteriorly; median prela narrowly rod-shaped; transverse prela stout, rapidly narrowed anteriorly. Caudal plate of prela wide, triangularly produced posteromedially. Lateral lobes absent. Ductus bursae extremely short, 0.16 × length of corpus bursae. Corpus bursae ovoid. Host plant. Unknown. Distribution. China (Sichuan). Etymology. The specific epithet is derived from the Latin brevissimus, referring to the extremely short ductus bursae.
