( Fig. 4 ) Material examined. Holotype male, China , Shaanxi , Daba Mountain , Ankang , 6.VII.2012 , Zejian Li, Mengmeng Liu . Paratypes : 2♂ 1♀ , same data as holotype . Etymology. The specific epithet is derived from the Latin protrudens (protrusive), referring to the stout parameres protruding out of the genital bulb. Diagnosis. Cerapanorpa protrudens sp. nov. resembles C. emarginata (Cheng) in the morphology of male genitalia, but can be separated from the latter by the following characters: (1) males lack wing markings (always with pterostigmal band and apical band in C. emarginata ); (2) paramere extending beyond gonostylus and bearing very short spines apically (nearly reaching the apex of gonocoxite and with thick long spines in C. emarginata ); (3) ventral basal plates of female genitalia folded ventrally (slightly expanded laterally in C. emarginata ). Description. Male: Head with frons, vertex and occiput black. Rostrum yellowish brown, maxillary palp yellowish brown. Antenna yellowish brown. Pronotum brownish black, with 10–12 black setae along anterior margin. Meso- and metanotum black; pleura and legs pale yellow, with tarsi yellowish brown. Forewing length 12.5–14.2 mm , width 3.2–3.5 mm ; wing membrane hyaline and without markings, pterostigma pale. Hindwing similar to forewing ( Fig. 4 A). Abdominal segments I–V brownish black for terga and sterna, ivory for pleural membrane; notal organ on tergum III semicircular, positioned on the small postnotal organ on tergum IV. Segment VI mostly brownish black, paler near hind margin, with a yellowish brown anal horn slightly curved downwards at apex ( Fig. 4 I). Segments VII–IX yellowish brown; segment VII very thin at base, with a long and narrow groove on dorsal surface; segment VIII as long as VII, slightly dilated apically. Male genitalia: Epandrium subquadrate and tapering toward the apex, with a deep U-shaped apical emargination ( Fig. 4 D). Hypovalves of hypandrium elongate, almost reaching base of gonostylus, with robust bristles along medial margins ( Fig. 4 C). Gonocoxite bearing a cluster of long setae on ventro-distal apex. Gonostylus roughly half length of gonocoxite, with a prominent basal process and an indistinct middle tooth on inner margin. Parameres extremely long, extending beyond gonostylus, slightly curved dorsad apically, with a row of short spines along medial margin. Dorsal valves of aedeagus elongate, extending to distal border of gonocoxite. Ventral valves short, membranous; lateral process auriform ( Fig. 4 E). FIGURE 4. Cerapanorpa protrudens sp. nov. (A) Male habitus; (B) female habitus; (C) and (D) genital bulb of male, ventral and dorsal views; (E) aedeagus, ventral view; (F) and (G) genital plate of female, ventral and dorsal views; (H) subgenital plate of female, ventral view; (I) abdominal segments V–VIII of male, lateral view. Scale bars: C, D, F & H = 0.20 mm, G = 0.25 mm, I = 0.50 mm. Female: Coloration as in males. Wings with faint pterostigmal band and apical band ( Fig. 4 B). Forewing length 14.4 mm , width 3.9 mm . Subgenital plate wide medially, gradually narrowed apically, with long setae along outer margin and shallow V-shaped incision at apex ( Fig. 4 H). Genial plate with main plate narrow basally, broadened distally, distal margin broadly U-shaped emarginated, forming a pair of short posterior arms ( Fig. 4 F, G). Ventral basal plates translucent, covering approximately 2/3 of main plate, largely folded ventro-laterally. Dorsal basal plates small and membranous. Axis proximally bifurcated and extending beyond main plate by nearly half its length, apex slightly extruding out of main plate. Distribution. China ( Shaanxi ).
