Ypsolopha sordida Sohn et Wu , n. sp. [ Figs 3 View FIGURES 1 – 6 and 9 View FIGURES 7 – 10 ]
Diagnosis: This species is close to Ypsolopha distinctata Moriuti and Y. parenthesella (Linnaeus) from East Asia and Y. ustella (Clerk) from Europe in external appearance and male genital features. It can be distinguished from the other two East Asian species by the proportionally narrower, more or less parallelsided valva (roundly broadened in the middle to 2/ 3 in distinctata and parenthesella ), and from Y. ustella by the obtusely angulate distal third of the costal margin of the valva.
Description: Head – Vertex with rough vestiture of orange-white, hair-like scales tipped with grayish brown; frons vestiture smooth, orange-white, slightly tinged with grayish brown. Antenna filiform, 1/3 as long as forewing; scape orange white dorsally, dark brown ventrally, with orange-white pecten; first 7-8 flagellomeres dark reddish brown, others with white and dark brown alternation on each segment. Labial palpus upcurved, terminally acute, reaching beyond vertex, orange-white dorsally, dark grayish brown ventrally; 2nd segment as long as 3rd, with dense scale tufts ventrodistally.
Thorax and abdomen – Patagium dark brownish gray; tegula dark brown, black laterally; mesonotum purplish brown, paler to lateral margins; a dark brown scales of tuft present on mesoscutellum. Fore- and midleg with coxa dark grayish brown intermixed with pale gray, lined with dark brown laterally; femur to tarsus dark grayish brown; distal end of femur dark brown. Hindleg with coxa dark brown; femur to tibia silvery orange white, tinged with grayish brown; tibia with setose tufts along ventral side; tarsus dark grayish brown. Forewing length 10.8 mm (n = 1), slightly narrow, with constant width throughout; apex round and termen oblique; costal area purplish brown, with black strigulae from base to 2/3; distal half of discal cell dark brown and a pale brown spot; dorsal area pale brown, with fuscous markings antemedially and posteromedially; dark brown marking present around base of posterior margin; fringe dark brown. Hindwing dark brown, paler to base; fringe dark grayish brown. Abdomen dark gray dorsally, pale grayish yellow ventrally, fuscous anteriorly.
Male genitalia ( Fig. 9 View FIGURES 7 – 10 ) – Uncus as wide as vinculum, rectangular, slighty convex posteromedially; socii relatively stout, terminally acute, 1/3 as long as valva; tegumen longer than wid, almost straight-sided; gnathos with scobinate, semicurcular medial plate. Valva elongate, costal and saccular margins parallel before terminal, distal portion of costal area obtusely angulate; entire dorsal margin and basal 1/3 of ventral margin narrowly sclerotized. Vinculum subhexagonal; saccus rectangular, protruding at angles, with a clubbed process as long as socii. Aedeagus slender, bent medially, minutely setose distally; coecum 1/3 as long as the rest of aedeagus; two spinulated bands of cornuti with long hair-like spines terminally.
Female genitalia – Unknown.
Type: Holotype – 3, Sangang, Mt. Wuyi, Fujian Prov., China, 10 VI 1981 (F Jiang), [ GSN: IOZ-09013], IZCAS.
Distribution: China (South).
Etymology: The species name, sordida , is derived from the Latin adjective sordidus, meaning “dirty” and refers to the brown forewing intermixed with fuscous specks in the new species.
