Figs 9–10
Diagnosis
The new species can be readily recognized by the following features: rostrum uniformly yellowish (Fig. 9C); hypovalves slender, with sparse short bristles along inner margins (Fig. 10A); parameres twisted in knee-shape, bearing long spines apically (Fig. 10D); dorsal valves of aedeagus brawny, expanded apically (Fig. 10E); main plate of medigynium flat, twice as long as wide, intensely constricted medially (Fig. 10G).
Etymology
The specific name refers to the type locality, Xuebaoding (Snow Treasure Peak) of the Minshan Mountains.

Description
Male
HEAD. Frons, vertex and occiput brownish black (Fig. 9 C–D). Rostrum uniformly yellowish, mandibles yellowish brown; maxillary and labial palps yellow with distal segments dark brown (Fig. 9C). Antennae brownish with 39–42 segments.
THORAX. Pronotum brown, with 12–14 stout setae along anterior margin. Meso- and metanotum grayish brown (Fig. 9D). Pleura light creamy white. Legs pale yellow, tibia with a pair of brown apical spurs; tarsi deep brown at the distal portion. Forewing length 13.7–14.6 mm, width 3.3–3.6 mm. Wing broad and membrane hyaline, almost without markings, except for the weak pterostigmal band (Fig. 9A); apical band faint, only with dark gray trace at apical region. Hindwing length 12.2–13.7 mm, width 3.1–3.5 mm, similar to forewing in pattern (Fig. 9A).
ABDOMEN. T1–T5 blackish, pleura ivory (Fig. 9E). Notal organ on posterior margin of T3 not prominent, postnotal organ on T4 very small, hook-shaped and projecting forward. A6 less than twice as long as A5, with a finger-like anal horn on posterior margin (Fig. 9E). A7 yellowish brown, with a narrow groove at base, constricted at basal half and slightly thicker towards apex. A8 light yellow, as long as A7, gradually thickening apically (Fig. 9E).
GENITALIA. Genital bulb yellowish and elliptical (Fig. 10 A–D). Epandrium extending beyond apex of gonocoxite, with a deep U-shaped terminal emargination between two stout setose lobes, bearing two clusters of dense long bristles on distal portion (Fig. 10C). Hypovalves of hypandrium slender, almost reaching apex of gonocoxite, with a column of sparse short bristles along inner margin (Fig. 10A). Gonocoxite approximately twice as long as gonostylus, with two subtriangular subapical teeth on ventral submedian margin. Gonostylus bearing a prominent basal process and an indistinct middle tooth on inner margin (Fig. 10A, D). Parameres yellowish brown and geniculate on apical portion, almost reaching apex of gonocoxite, bearing long spines apically (Fig. 10D). Dorsal valves of aedeagus brawny and inflated apically, almost reaching distal border of gonocoxite; ventral valves short, membranous; a small narrow lateral process from basal margin of dorsal valves (Fig. 10E).
Female
HEAD, THORAX AND ABDOMEN. Similar to those of male in coloration and patterns (Fig. 9B). Forewing length 14.0– 15.3 mm, width 3.5–3.8 mm, markings and venations similar to male except for the more distinct pterostigmal band; hindwing length 13.9–15.1 mm, width 3.3–3.7 mm, similar to forewings (Fig. 9B).
GENITALIA. Subgenital plate lingulate, with a trapezoidal emargination terminally, bearing long setae on lateral distal margin (Fig. 10H). Medigynium small and sclerotized; the main plate flat, twice as long as wide, intensely constricted medially (Fig. 10G). Paired posterior arms gradually narrowing toward apex, forming a deep U-shaped emargination (Fig. 10 F–G). Ventral basal plates translucent, covering approximately three-quarters of the main plate (Fig. 10H). At the base of the main plate, paired dorsal basal plates circular and membranous (Fig. 10G). Axis elongate, with apex slightly extruding out of main plate, and base bifurcated, slightly extending beyond main plate (Fig. 10 F–G).
Distribution
Sichuan Province, China.
Remarks
The new species resembles C. brevicornis (Hua & Li, 2007) from the Bashan Mountains in body coloration and the wings pattern, but is easily separated from the latter by the shape of geniculate parameres and the brawny dorsal valves of aedeagus.
