Edosa conchata Yang, Wang & Li , sp. nov.

( Figs 4 View FIGURE 4 , 19 View FIGURES 19 c, 38, 69)

Type material. Holotype ♂, CHINA: Menglian County (22°19'N 99°34'E), Pu'er, Yunnan Province, 30.x. 2010, 950 m, leg. Bingbing Hu, Jing Zhang & Yanpeng Cai, genitalia slide No. YLL11011.

Diagnosis. This new species is similar to E. sinica (Gaedike, 1984) , but can be distinguished from the latter by having a scallop-shaped valva, which is ear-shaped in E. sinica .

Description. Adult ( Fig. 38 View FIGURES 36 − 43 ). Wingspan 13.0 mm in male. Vertex dusty yellow, scales deciduous, frons pale yellowish brown. Antenna dusty yellow, 0.8× length of forewing; scape mixed with darker scales anteriorly, with a few black pecten bristles; flagellum unicolorous. Labial palpus yellowish brown on inner surface, ferruginous brown except yellowish brown at apex of third segment on outer surface. Thorax and tegula blackish brown. Forewing index 0.27, yellowish brown, with dark-tipped scales apically; retinaculum present; cilia yellowish brown, scales with darker tips. Hindwing grayish brown, with a single short, slender evenly curved frenular bristle; cilia grayish brown. Fore and mid legs purplish brown; hind leg yellowish brown, tibia mixed with dark brown on outer surface.

Pregenital abdomen. In male, first tergum without sclerotized; coremata present in eighth segment; eighth sternite 0.3× as long as wide, posterior margin slightly concave, without caudal process; eighth tergite trapezoidal, without caudal process.

Male genitalia ( Fig. 69 View FIGURES 68 − 70 ). Vinculum convex on anterior margin, slightly concave on posterior margin; medial process on ventrocaudal margin elongate, T-shaped, 0.8× depth of vinculum. Tegumen 0.3× depth of vinculum, weakly sclerotized, anterior margin slightly concave. Uucus with lobate base separated by membrane; uncus lobe small, not twisted, basal half expanded, membraneous, distal half digitate, bent ventrad, sclerotized, setose; sclerite absent between uncus lobes. Valva scallop-shaped; costal margin straight, without basal flange, with a small, melanized horn at tip; basal margin with small, triangular ‘secondary apodeme’ close to ventral margin; apical margin gently convex, with melanized serration, not distinguishable from ventral margin; ventral margin denticulate, elliptically convex, forming deep ventral lobe; inner surface unmodified. Juxta reflexed anteriorly along inner surface of vinculum, 0.4× length of aedeagus, heavily sclerotized, grooved in dorsal midline, folded laterally, curved through 60° with base of aedeagus. Aedeagus 2.0× length of valva, tubular, double-walled, slender, gently curved. Bulbus ejaculatorius 2.0× length of aedeagus, slightly expanded in basal 1/5, where ductus ejaculatorius is coiled, subdistal section expanded and curved, distal section expanded, cup-like.

Female unknown.

Distribution. China (Yunnan).

Etymology. The specific name is derived from the Latin conchatus, meaning conchoidal, referring to the scallop-shaped valva.
