description: Cerapanorpa sinuata sp. nov.
(Fig. 5)
Material examined. Holotype male: China, Shaanxi, Pingheliang (2300 m), Huoditang, Ningshan County, 6.VII.2010, Baozhen Hua. Paratypes: 5♂ 6♀, same data as holotype.
Etymology. The specific epithet is derived from the Latin sinuata (sinuate), referring to the extremely sinuate parameres of the male genitalia.
Diagnosis. The new species resembles C. obtusa (Cheng) in the morphology of male genitalia, but can be readily differentiated from the latter by the following characters: (1) gonocoxite with a very large concave area apico-medially (only slightly concave in C. obtusa); (2) paramere strongly sinuate, apical half curved (slightly geniculate near apex in C. obtusa); (3) dorsal valves of aedeagus short, not reaching apex of gonocoxite, with truncated apex (elongate, reaching basal part of gonostylus, obtuse apically in C. obtusa).
Description. Male: Rostrum yellowish brown anteriorly, light yellow laterally (Fig. 5 F). Frons, vertex and occiput brownish black. Antenna dark brown. Thorax black dorsally and pale yellowish laterally, with eight black setae along anterior margin of pronotum. Legs light yellow, with tarsi darkened toward apex. Forewing length 12.0–13.0 mm; width 3.0 mm; wing membrane hyaline, without markings (Fig. 5 A). Terga I–V brownish black, corresponding sterna paler; notal organ on tergum III semicircular; postnotal organ on tergum IV small, hookshaped, projecting forwards. Anal horn on tergum VI brownish black basally, yellowish brown apically (Fig. 5 E). Segments VII–IX yellowish brown; segments VII and VIII elongate, nearly of equal length; basal half of segment VII much thinner than apical half and grooved dorsally; segment VIII gradually thicker toward apex.
Male genitalia: Genital bulb nearly rounded. Hypovalve bearing a regular line of robust bristles on medial margin (Fig. 5 C). Gonocoxite with a large concave area on apical inner margin. Gonostylus slightly curved mesad, with an indistinct middle tooth. Basal process of gonostylus with fine setae on ventral edge. Parameres sinuate and posteriorly curved, with dense comb-like spines along medial margin (Fig. 5 C). Dorsal valves of aedeagus short, below apical border of gonocoxite, with truncate apex and membranous apical process (Fig. 5 D).
Female: Forewing length 12.5–13.0 mm; width 3.3–3.5 mm. Wings almost hyaline, only with vague apical and pterostigmal bands (Fig. 5 B). Abdominal segments I–VI brownish black except for yellowish pleural membrane; terminal segments entirely yellowish brown. Subgenital plate ligulate, with long setae along outer margin (Fig. 5 J). Main plate flat, expanded distad; two posterior arms converging mesad; ventral basal plates fused into a membranous piece; paired dorsal basal plates small, more sclerotized than ventral plates; anterior part of axis bifurcate, and extending beyond main plate by less than half its length (Fig. 5 G–I).
Distribution. China (Shaanxi).
