Chibiraga houshuaii Ji & Wang View in CoL sp. nov.
( Figs. 3 View FIGURES 1–4 , 7 View FIGURES 5–8 , 11, 12 View FIGURES 9–14 )
Type material. Holotype: Male, 4-VIII- 2 013, Gaofeng Town, Lufeng County, Gaoxiong City, Yunnan Province, altitude 2230 m, leg. Min Wang, Hailing Zhuang, and Yu Wang, SCAU; Paratype: 1 male, same data as those of the holotype, SCAU.
Diagnosis. The species is externally similar to C. banghaasi but male genitalia differs in (1) uncus absent, socii mushroom-shaped; (2) ventral and dorsal part of valve almost the same size; (3) distal tip of aedeagus not curved. See diagnostic differences with C. yukei below.
Description. Forewing length 9.5– 10 mm (n=2). Head, thorax, and abdomen covered with reddish brown to black brown scales. Antenna stem reddish brown, with pale brown rami. In males, antenna bipectinate, gradually tapering at the tip. Labial palpus short, close to vertex, 1 st segment curved upward, brown; 2nd segment bent at a right angle from the 1st, stout and relatively long, almost three times as long as those in the 1st, brown; 3rd oval, yellowish. Forewing blackish brown to dark brown in basal two-thirds and pale reddish brown in outer one-third. Reddish scales present at costa and wing base in basal two-thirds, while white scales form an obscure band extending from the costa to vein CuA 2 in outer one-third. Fringes yellowish brown. A black postdiscal fascia run straight from costa to vein CuA1, turning slightly outward and extending at an anal angle. Black scales concentrate in space 1A+2A, Cup, CuA2, discocellular vein, and center of the cell, forming two prominent black spots; the spot near the dorsal margin is larger and rounder. Hindwing generally pale reddish brown to black brown, black scales scattered in basal half and concentrated at the anal angle. Venation ( Figs. 11, 12 View FIGURES 9–14 ) is virtually identical to that of C. banghaasi (Hering & Hopp) .
Male genitalia ( Fig. 7 View FIGURES 5–8 ). Uncus absent, socii large, fleshy, mushroom-shaped, with many setae; subuncus bellshape, with setae. Gnathos consists of two branches, paired branches swollen apically and connected to each other by a relatively wide medial bridge. Tegumen broad and relatively short. Valvae deeply concave in the middle, dorsal part of the valvae oval, with setae at the tip, base of dorsal part with a peculiar appendix covered with setae; ventral part of the valvae nearly triangular, flattened, bearing a process in the apex, and possessing setae from tip to base. Juxta upper bow-shaped, bottom with two triangular and one semicircular processes. Saccus simple, arcshaped. Aedeagus slender and straight, distal tip abruptly pinched.
Distribution. China (Yunnan, Henan).
Etymology. The species is named after Dr. Houshuai Wang (SCAU), a scientist specializing in Lepidoptera fauna, who provided useful advice and kind help.
