Cerapanorpa liupanshana sp. nov.

( Fig. 3 View FIGURE 3 )

Material examined. Holotype male: China, Ningxia, Liupan Mountain (elev. 2380 m), 5.VII.2008, Qiulei Men . Paratypes: 3♂ 5♀, Ningxia, Liupan Mountain (elev. 2100–2380 m), 26.VI.–12.VII.2008, Qiulei Men & Shuyu Liu. Etymology. The specific epithet is derived from the type locality, Liupanshan.

Diagnosis. Cerapanorpa liupanshana sp. nov. is closely allied to C. dubia (Chou & Wang) comb. nov. in appearance and male genitalia, but can be distinguished from the latter by the following characters: (1) rostrum reddish brown or darker (mostly yellow, rarely black in C. dubia ); (2) paramere shorter, not exceeding beyond gonocoxite, with spines on dorso-mesal line (extending well beyond gonocoxite, with spines along medial margin in C. dubia ); (3) female genital plate small, squat (larger, slender in C. dubia ).

Description. Male: Head brownish black on frons, vertex and occiput. Rostrum reddish brown anteriorly, pale yellow laterally. Antenna yellowish brown. Pronotum brownish black, with 10–12 black setae along anterior margin. Meso- and metanotum brownish black; pleurites and sternites pale yellow. Legs pale yellow, with tarsi yellowish brown. Wings hyaline, immaculate, or with only faint indication of pterostigmal band and apical band ( Fig. 3 View FIGURE 3 A). Forewing length 12.0–13.0 mm, width 3.0– 3.1 mm. Abdominal segments I–V brownish black on terga and sterna, ivory on pleural membrane; hind margin of tergum III produced into a semicircular notal organ; postnotal organ on tergum IV very small, hook-shaped and projecting forward. Segment VI entirely brownish black, with yellowish brown digitate anal horn on its postero-dorsal part ( Fig. 3 View FIGURE 3 I). Segments VII–IX yellowish brown; basal half of segment VII very thin, with a longitudinal groove on dorsal surface, fitting anal horn on tergum VI.

Male genitalia: Genital bulb oval. Epandrium subquadrate, with a shallow apical emargination ( Fig. 3 View FIGURE 3 D). Hypovalves of hypandrium broad, nearly extending to apex of gonocoxite, each with long bristles along medial margin ( Fig. 3 View FIGURE 3 C). Gonocoxite approximately twice as long as gonostylus, bearing 4–5 black setae on ventro-distal area. Gonostylus with a large basal process and an indistinct middle tooth on medial margin ( Fig. 3 View FIGURE 3 C). Parameres thin, reaching apex of gonocoxite, with a row of short spines on dorsal surface; apex of paramere slightly curved medially, pointed apically. Dorsal valves of aedeagus elongate, slightly tapering toward the apex; ventral valves short, membranous; lateral process auriform ( Fig. 3 View FIGURE 3 E).

Female: Coloration and wing patterns ( Fig. 3 View FIGURE 3 B) similar to males. Forewing length 12.5–13.5 mm, width 3.4– 3.6 mm. Subgenital plate lingulate, with long setae on lateral and caudal margins ( Fig. 3 View FIGURE 3 H). Genital plate small, yellowish brown, weakly sclerotized. Main plate narrow at basal half, broadened distally ( Fig. 3 View FIGURE 3 F). Posterior arms tapering toward the apex, paler tinged. Paired dorsal basal plates small, sclerotized. Ventral basal plates fused into a thin membrane. Axis elongate, its basal bifurcated part extending beyond main plate.

Remarks. Variation mainly concerns the rostrum coloration, wing markings, and female genital plate. Most individuals have a reddish brown rostrum, others a yellowish brown rostrum. The main plate is distinctly thinner basally, and broaden distally, or constricted at the middle in some specimens.

Distribution. China ( Ningxia).
