Diagnosis. Superficially, this species is not easily distinguished from its allies, but the orange patch of the forewing is somewhat smaller than that of congeners. The male genitalia are characterized by the elongated pentagonal uncus, the medially thickened gnathos, and a short projection of the juxta. In the female genitalia, the signum is larger than that of related species.

Description. Adult ( Fig. 58 View FIGURES 54–61 ). Head: Silvery white. Labial palpus silvery white, palpomere II mixed with light brown on outer surface; palpomere III as long as II, mixed with light brown and fuscous. Antenna with scape silvery white; flagellum dark fuscous except basal 1/3 of dorsal surface silvery white, male cilia slightly longer than diameter.

Thorax: Dorsum and tegula silvery white. Wingspan 7.5–8.5 mm; forewing with basal 1/3 silvery white mixed with grey, anterior edge of costa black, distal 2/3 grey; an elliptical orange patch in distal 1/3 of wing between costa and posterior 1/3, its outer margin extending almost to apical spot; silvery white between patch and apical spot, extended along termen as a narrow line; below apical spot a smaller black spot on termen; fringe scales grey. Hindwing grey except apex black; fringe scales grey. Legs silvery white to light grey; mid-tibia sometimes slightly suffused with fuscous near apex; hind tibia strongly mixed with fuscous after middle; mid- and hind tarsi mixed with fuscous.

Abdomen ( Fig. 21 View FIGURES 15–25 ): Male coremata slightly shorter than sternum VIII; sternum VIII pentagonal, approximately 1/7 length of abdomen. Male genitalia ( Fig. 77 View FIGURES 72–77 ) with uncus small, elongated pentagonal, protruded medially. Gnathos hook short, thickened at middle, pointed apically. Tegumen approximately 5 times as long as uncus; papilliform tubercles at middle, each bearing a long single hair ( Fig. 38 View FIGURES 26–45 ). Valva slender, uniformly elongate from base to near apex, curved inward at middle, slightly broadened and rounded apically. Anellus lobe ovate, approximately 1/5 length of valva; apical bristle slightly longer than anellus lobe, strongly curved inward. Juxta with a short projection at distal 1/3 of inner margin. Vinculum broad, posterior margin rounded. Saccus sub-triangular, broad basally, rounded apically. Aedeagus with basal 2/5 globular, distal 3/5 slender and slightly curved downward. Female genitalia ( Fig. 93 View FIGURES 91–94 ) with papillae anales simple and setose. Apophyses anteriores approximately 1/3 length of apophyses posteriores. Tergum VIII with posterior margin deeply incised at middle; sternum VIII shorter than tergum VIII, broadly convex anteriorly. Ostium bursae round, situated at middle of sternum VIII. Ductus bursae slender, slightly broadened near corpus bursae, colliculum in posterior 1/3, ductus seminalis arising from posterior 2/5. Corpus bursae elongate-ovate, slightly longer than ductus bursae, constricted at middle; signum elliptical or elongate diamondshaped, between posterior 1/6 and 1/2 of corpus bursae.

Distribution. China (Guangxi, Hainan, Jiangxi, Zhejiang).

Etymology. The species name is derived from the Latin crassus (thickened) and medius (middle), referring to the medially thickened gnathos in the male genitalia.
