Figs 7–8
Diagnosis
The new species differs from its congeners primarily in the following features: rostrum uniformly brownish black anteriorly (Fig. 7C); hypovalves thin at base, gradually broadened toward apex (Fig. 8A); parameres long, hook-shaped, bearing long spines along inner medial margin (Fig. 8A); dorsal valves of aedeagus tapering abruptly toward apex, curved ventrally, bearing a large L-shaped dorsal process (Fig. 8 E–F); female medigynium with a pair of large and oblong dorsal basal plates, approximately as long as half the main plate.
Etymology
The specific epithet is derived from the type locality, Taizishan (Mount Prince).

Description
Male
HEAD. Frons, vertex and occiput black. Compound eyes dark grey. Rostrum brownish black anteriorly, light brown laterally, mandibles dark brown; labial and maxillary palps light brown with distal segments dark brown (Fig. 7C). Antennae filiform and black with 38–42 flagellomeres.
THORAX. Pronotum blackish brown, with 8–12 setae along its anterior margin; meso- and metanotum black (Fig. 7D). Pleura light grayish yellow. Legs pale yellow with a pair of black apical spurs; tarsi yellowish brown and darkened toward apices. Forewing length 11.8–12.3 mm, width 2.9–3.1 mm. Wing membrane hyaline, only with degenerated brown pterostigma and faint apical band. Hindwing length 11.6–12.0 mm, width 2.7–3.0 mm, similar to forewings in pattern (Fig. 7A).
ABDOMEN. A1–A5 terga and sterna entirely black, ivory on pleural membrane (Fig. 7E). Notal organ on posterior margin of T3 very short and not prominent. T4 bearing a small harb-shaped postnotal organ. T6 uniformly brownish black, with a brown finger-like anal horn on posterior margin (Fig. 7E). A7–A8 yellowish and elongate, slightly restricted at base, gradually wider toward apices. A7 with a narrow groove on dorsal surface (Fig. 7E).
GENITALIA. Genital bulb nearly globular, yellowish brown (Fig. 8 A–C). Epandrium broad basally, narrowing toward apex, with a deep U-shaped terminal emargination between two stout setose lobes (Fig. 8C). Paired hypovalves thin basally, broadening toward apex, bearing long bristles along inner margins (Fig. 8A). Gonocoxite with very small concave area on apical inner margin. Gonostylus with a large basal process and an indistinct middle tooth on medial margin, and bearing a bundle of stout setae dorsally on basal process (Fig. 8D). Parameres long and hook-shaped, extending well beyond the apex of gonocoxite, bearing long spines along inner medial margin; apex of paramere bearing a brown stout spine, pointed apically (Fig. 8A). Dorsal valves of aedeagus short, tapering abruptly toward apex and curved ventrally, bearing a large L-shaped dorsal process (Fig. 8 E–F); ventral valves membranous and short; lateral process prominent and curved ventrally (Fig. 8 E–F).
Female
HEAD, THORAX AND ABDOMEN. Similar to male in coloration and patterns. Forewing length 12.9–13.2 mm, width 2.9–3.3 mm; wing pattern similar to male, except for more extensive wing markings. Hindwing length 11.8–12.2 mm, width 2.8–3.1 mm, similar to forewing (Fig. 7B).
GENITALIA. Subgenital plate lingulate, with a shallow V-shaped incision at apex, bearing long setae on lateral distal part (Fig. 8I). Main plate of medigynium narrow basally, gradually broadening toward apex. Paired posterior arms tapering toward apex, forming a broad trapeziform emargination (Fig. 8 G–H); ventral basal plates translucent, folded ventro-laterally, covering two-thirds of main plate (Fig. 8G); paired dorsal basal plates large and oblong, approximately as long as half the main plate, more sclerotized than ventral basal plates (Fig. 8H); anterior part of axis bifurcated, extending anteriorly less than half its length beyond main plate (Fig. 8 G–H).
Distribution
Gansu and Qinghai Provinces, China.
Remarks
Cerapanorpa taizishana sp. nov. resembles C. nanwutaina and C. obtusa in appearance from the Qinling Mountains, but is readily distinguished from the latter two species by the conspicuously hook-shaped paramere, L-shaped dorsal process of aedeagus, and specific medigynium.
