Dicerapanorpa bifurcata Hu & Hua sp. nov. urn:lsid:zoobank.org:act: E02C50F8-920B-4A40-B7BD-EA4666930497 Figs 2–3 Diagnosis This species can be readily recognized by the following characters: basal branch of male paramere absent; mesal branches elongated, convergent distally, and extending to the median tooth of gonostylus; lateral branch curved semicircularly at base and convergent at apex, exceeding basal process of gonostylus (Figs 2D, 3 A–B); and female medigynium strongly folded ventrally on each side, bearing a short basal stalk, with rounded main plate beneath the basal stalk (Figs 2F, 3C). Etymology The specific epithet refers to the bifurcated paramere of the male genitalia. Type material Holotype CHINA – Sichuan Province • ♂; Pingwu County, Wanglang Nature Reserve; 32.92° N, 104.16° E; 2500 m a.s.l.; 2 Jun. 2018; Kai Gao leg.; NWAU. Paratypes CHINA – Sichuan Province • 2 ♂♂, 14 ♀♀; same data as for the holotype; Kai Gao and Yu-Ru Yang leg.; NWAU • 1 ♂; Maoxian County, Tudiling; 31.71° N, 103.92° E; 2500 m a.s.l.; 21 May 2018; Kai Gao leg.; NWAU. Description Male HEAD. Head mostly yellow. Rostrum faint yellow, with pair of blackish longitudinal stripes laterally. Maxillary and labial palps yellowish brown, distal segment dark brown. Antenna black brown. Ocellar triangle black (Fig. 2A). THORAX. Pronotum yellow, with short black setae along anterior margin and two black longitudinal stripes laterally. Meso- and metanotum pale yellow with black longitudinal stripe on each side. Pleura and sterna yellow. Legs pale brown, distal tarsi dark brown (Fig. 2A). WING. Forewing length 13.4 mm, width 3.4 mm; membrane hyaline; apical and pterostigmal bands reduced to discontinuous spots, other markings absent. Hindwing length 12.5 mm, width 3.3 mm, similar to forewing in coloration and pattern (Fig. 2A). ABDOMEN. T1–T5 yellow, with two black longitudinal stripes laterally. Notal organ on T3 slightly developed, semicircular, bearing numerous stout setae posteriorly. Post-notal organ on T4 pointed, projecting forward. Sterna and pleura yellowish. A6 yellowish brown, bearing two short digitate anal horns on posterior margin. A7 yellowish, elongated, constricted basally, abruptly dilated distally. A8 yellow, evenly broadening toward apex (Fig. 2A). GENITALIA. Genital bulb ovoid, yellowish brown. Epandrium (tergum IX) broad basally, constricted at distal third, terminating with deep trapezoidal emargination between two parallel setose lobes (Fig. 2C). Hypovalves broad, divergent apically, covered with long black bristles along inner margin, reaching apex of gonocoxite. Gonostylus shorter than gonocoxite, smoothly curved convergently; basal process gradually narrowing toward acute tip; median tooth subtriangular (Figs 2D, 3A). Basal branches of parameres absent; mesal branches elongated, curved convergently, extending to median tooth of gonostylus; lateral branch curved semicircularly near base and convergent at apex, slightly exceeding basal process of gonostylus (Fig. 3B). Ventral valves of aedeagus short and slender; dorsal valves separated apically, greatly elongated, reaching apex of gonocoxite (Fig. 3B). Female HEAD, THORAX AND ABDOMEN. Similar to males in general appearance (Fig. 2B). Forewing length 14.5– 15.8 mm, width 3.9–4.1 mm; hindwing length 13.3–14.4 mm, width 3.9–4.1 mm. GENITALIA. Subgenital plate trapezoidal, terminating in ligulate process, covered with long bristles caudally (Fig. 2E). Medigynium strongly folded ventrally on each side, bearing short stalk at base, with round main plate beneath basal stalk. Posterior arm stout, nearly half as long as main plate. Axis concealed in main plate, slightly protruding apically (Figs 2F, 3C). Distribution Minshan Mountains, Sichuan Province, China (Fig. 1).
