Pseudacroclita damingshana Zhang , sp. nov.

( Figs. 1, 3, 5 )

Diagnosis. This species is similar to Pseudacroclita micrancistra Zhang & Li but differs by having the terminus of the socius straight on the inner margin, the costa of the valva arc-shaped, and the width of neck of valva about as long as 1/4 of the outer edge of the cucullus in the male genitalia. In the female genitalia, the corpus bursae is nearly round, shorter than the ductus bursae. In contrast, in P. micrancistra the terminus of the socius extends inward forming a hook-like process, the costa of the valva is nearly straight, and the width of neck of valva is about as long as 1/3 of outer edge of the cucullus in the male genitalia. In the female genitalia, the corpus bursae is pyriform, much longer than the ductus bursae.

Description. Adult ( Fig. 1 ). Head: Vertex with light brown scales, frons white. Antenna brown. Labial palpus gray mixed with brown, inner surface white; terminal segment porrect, with basal part concealed in long scales of second segment. Thorax: Dorsum and tegula grayish brown. Legs gray, with brown scales on tibiae and tarsi. Forewing length 6.0–7.0 mm. Forewing ground color brown, scattered with some lighter streaks; apex gray and falcate; termen concave, bordered by grayish white scales with brown basal line; costa with eight pairs of gray strigulae; basal three pairs located from base to about costal 1/3, the first pair composed of one streak; the fourth and fifth pairs between Sc and R1; distal three pairs distributed between pairs of veins R1-R2, R2-R3, R3-R4, confluent with each other and extending toward termen; basal patch originating from 1/3 of costa to 1/3 of dorsum with outer margin protruding; median fascia inconspicuous; ocellar patch white, irregularly rectangular, with silvery gray scales near its outer margin; cilia gray. Hindwing and cilia gray. Abdomen: Male genitalia ( Fig. 3 ) with uncus rudimentary; socius broadly ovoid, hairy, terminus with inner margin straight. Valva with cucullus much larger than sacculus, with distinct neck, neck 1/4 width of outer edge of cucullus; costa somewhat arc-shaped; sacculus angle acute, protrudent, setose; cucullus elongate triangular, hairy, with a slender spine on ventral angle. Phallus broad; cornuti numerous, spiculate. Female genitalia ( Fig. 5 ) with papilla analis slender, hairy; apophyses posteriores as long as apophyses anteriores. Sterigma somewhat triangular, produced into two tapering angles posteriorly. Ductus bursae broad; colliculum short, near ostium. Ductus seminalis originating from entrance of corpus bursae. Corpus bursae nearly round, shorter than ductus bursae, with a sclerotized ring around its entrance; two horn-like signa, different in size.
