Striogyia acuta View in CoL sp. nov. ( Figs 4 View Figures 1–4 , 8 View Figures 5–8 )
Diagnosis. The new species is similar to S. obatera Wu, 2011 , but differ from the latter by the longer valva and the acute apex of the juxta in the male genitalia. The main external difference in external is that S. acuta does not have the discal spot found on the forewing of S. obatera . The 8th sternite is shorter than that of S. obatera . The juxtal apex of S. obatera is chimney-shaped.
Description. Male wing expanse about 20.0 mm. Forewing length about 9.0 mm. Labial palpus long, porrect, apex pointed. Body pale brown. Forewing pale yellowish brown; discal spot bar-shaped; postmedial line pale gray, straight. Hindwing pale brown.
Male genitalia. Eighth sternite concave in distal margin, bearing dense spines; tegumen sclerotized weakly; uncus and gnathos absent; valva long, arm-shaped, narrow near base; transtillae combined into one, bearing a pair of short lobes and a pair of long processes, which longer than half of valva-length; juxta ring-shaped, apically with a long angular process, apex pointed; aedeagus slender, longer than valva-length, densely with small spines in apical portion.
Female genitalia. Unknown.
Material examined. Holotype (♂). Shaanxi, Taibai , 1350 m, 1980.VII.13, Baolin Zhang leg. (gen. slide no. W10038, deposited in IZCAS).
Distribution. Shaanxi (Taibai).
Etymology. The specific name is derived from Latin “ acutus ” (= acute), corresponding to the acute apex of the juxta.
