Abstract: The genus Cnephasitis of the Subfamily Tortrieinae, tribe Polyorthini, established by Razowski, 1965, is a small group with limited distribution in the south of Asia. This paper records 2 species of chinese Cnephasitis Razowski, one species is deseribed as new and one species is recorded for the first time. All specimens are kept in the Institute of Zoology, Aeademia Sinica.1. Cnephasitis apodicta DiakonoffDistribution: Sichuan Province (Mt. Emei, 1800-2000m. 12. Ⅶ. 1957).2. Cnephasitis spinata sp. nov.Male wing expanse 27-28 mm. Head ochreous; antennae dark, with minute cilia. Labial palpus projecting 3 times longer than the diameter of an eye outside dark brown, inside yellowish-brown; porrect or slightly drooped; terminal segment cylindrical; middle segment convex dorsally, triangular in shape. Thorax brown. Forewing ovale;costa arched along anterior third, posterior 2/3 gradually curved, apex obtusely pointed; termen strongly rounded; apparently with small tufts of scales on wing surface. Basal patch small and edge inwards oblique; median fascia and costal patch indistinct. Costa and termen with obvious fringes. Hindwing greyish ochre, costa pale, apex dark, fringes on termen and dorsum. Forewing Cu2 from 2/3 of cell, Cu1 from angle; three median veins parallel to each other, M2 nearer M3 than M1 basally, R4 and R5 stalked from angle, R3 near R4+5 in the 1/3 of Rz and R4t5 E, near R3 in the 1/3 of R1 and Rs. Hindwing R5 and M1 short-stalked, M3 and Cu1 short-stalked from upper land lower angle separately, Cn2 from beyond 4/5.Male genitalia: Tegumen slightly higher then broad. Uncus with triangular base and a slender hook,obtuse terminally. Socius stout, oval, drooped. Gnathos broad, arms slender and almost semicircular, hook simple, obtuse. Transtilla triangular membranous thickening with very dense aciculae. Valva oblong-suboval, below costa with a split to beyond middle. Saeeulus somewhat sclerotized, with a strong prong at 2/3 length of valva. Aedeagus oval, cylindrical, ending in two large prongs, one terminally and the other at 1/3.Holotype ♂,Ya Dong Xizang (Tibet), 24. Ⅷ. 1978, Li Guang-wu. Paratypes 2 ♂♂, locality and collector as holotype, 22, Ⅷ, 24.1978. The male genitalia of spinata very similarito those of dryadarcha but differ from the later chiefly by the position of the strong Prong on 2/3 of the saceulus, not on 1/3.
