description: <i>Sinopanorpa nangongshana</i> Cai &amp; Hua, sp. nov. (Fig. 4) <b>Holotype</b>: male, <b>Shaanxi</b>: Mt. Nangongshan (32°18'N, 108°53'E), 1800 m, Langao Co., 25.vi.2007, leg. BZ Hua &amp; JL Tan. <b>Paratypes</b>: <b>Shaanxi</b>: 1&amp;male; 1&amp;female;, same data as holotype. <b>Etymology:</b> The specific name is derived from the type locality, Mt. Nangongshan. <b>Diagnosis:</b> The new species resembles <i>Sinopanorpa digitiformis</i> <b>sp. nov.</b> and <i>Sinopanorpa tincta</i> (Navas) in wing patterns, coloration, and hypovalves. However, it can be readily differentiated from the two other species by 1) wings paler; 2) ventral parameres very long and divergent, extending to 3/5 of gonostylus; 3) the basal lobe of gonostylus much narrower and bifurcated transversally at apex; 4) genital plate in female elongate, axis very thick, extending nearly one third of its length beyond the plate. Male (Fig. 4A): Head dark brown. Eyes blackish. Ocellar triangle dark brown. Vertex dark reddish brown, with a dark brown transverse band through ocelli between eyes and five longitudinal dark brown stripes, three of them extending to occiput. Frons yellowish brown. Antennae dark brown, long filiform with 44–45 segments. Rostrum grayish yellow, with three longitudinal narrow stripes dorsally. Labrum and maxillae grayish yellow; mandibles dark reddish brown; maxillary palpi grayish yellow except the distal half of the apical segment brown. Thorax: Dark brownish dorsally and yellowish white laterally. Pronotum with a row of 12 black setae along the anterior margin. Tegula dark, with many short setae. Legs yellow with grayish brown hairy region at the anterior base of coxa. Coxa and femur without seate; tibia with a pair of yellowish long apical spurs and three rows of setae; tarsomeres with two rows of black spines on ventral surface and a crown of apical black setae; claws serrate with five teeth. Wings: Forewings 16.2–17.1 mm long, 3.3–3.4 mm wide. Forewing membrane bright yellow in colour, with pterostigma distinct and orange-red in colour. Markings grayish to brown. Apical band broad and light grayish, reaching posterior margin. Pterostigmal band prominent with complete basal and distal branches equal in width, but the distal branch vaguer, similar to the colour of apical band. Marginal spot rectangular, extending from R 1 to R 4+5. Basal band almost complete, only broken between vein R 1 and Rs, and gradually becoming widened from CuA towards posterior margin. Basal spot absent. Vein R 2 three-branched. Hindwings similar to forewings in wing pattern, but with marginal spot and basal band absent (Fig. 4A). Forewings with 5–7 jugal bristles, and hindwings with 1–2 frenular bristles. Abdomen (Fig. 4B): Terga I–V dark brown, with mottled irregular blackish markings, black along the posterior margins. Sterna yellow and pleura pale with spiracles clearly visible. Notal organ on 3rd tergum undeveloped. Segments VI–VIII greatly elongated with terga and sterna completely fused together and shining reddish brown in colour. A6 twice as long as A5, with a cluster of yellowish hair on the mid dorsal part, and the distal half of this segment tapering towards apex. A7 almost same length as A6, and constricted at basal 1/3, then swelling suddenly with numerous dark hairs located on the anterior-dorsal angle along the middle dorsal line. A8 similar to A 7 in length but markedly thinner than A7, slightly constricted at basal 1/4 (Fig. 4B). A black longitudinal line at dorsal margin of pleura, prominent on A2–8. Another longitudinal line along spiracles, straight on A6–8, but as an oblique on A1–5 under spiracles. Male genitalia (Figs. 4C–F): Genital bulb long elliptic (Fig. 4C–D). Epandrium (9th tergum) dark, broad at base, slightly narrowing towards apex, with a shallow apical emargination, cerci visible from above (Fig. 4C). Hypandrium (9th sternum) short and dark; hypovalves yellowish, broad and long, reaching the apex of gonocoxite, but parallel and close to each other (Fig. 4D). Gonocoxites blackish, slightly longer than the yellowish gonostyli. Gonostyli quite long and slender, evenly curved outwards, each with a prominent triangular mesal process; the basal lobe narrow, strongly sclerotized, bifurcated at apex (Fig. 4E). Ventral parameres strikingly long, bending dorsally and extending over mid part of gonostylus and far beyond the mesal process; ventral parameres with very short thin spines along the mesal and dorsal margin of their distal 3/4, only the proximal 1/4 smooth and bare; the basal part of ventral parameres separate broadly, the apices prominently divergent, at their apical third close to each other, making the two parameres appearing as a large X-figure. Dorsal parameres short and simple, forming a broad U-shape. Penis dark and greatly reduced, situated between the bases of dorsal parameres (Fig. 4F). Female: Head dark reddish brown. Thorax dark blackish brown dorsally, light brown laterally. Forewings 16 mm long, 3.3 mm wide. Similar to male except wing markings vaguer, apical band with a rectangle spot extending forwards between R 5 and M 1; marginal spot absent; basal band greatly reduced to a large spot along posterior margin. Hindwings similar to forewings in wing pattern, but with marginal spot and basal band absent, apical band with a window between R 5 and M 1. Terga I–IV dark brown, V–VII brown; sterna I–V light yellow, VI–VII dark yellow; segments VIII–IX light yellow. Female genitalia (Fig. 4G–H): Subgenital plate broad, with a nearly unnoticeable distal emargination, bearing long setae along apical part (4G). Internal skeleton elongate and slightly constricted in the middle part; a pair of posterior arms forming a U shape with stunt apex. The axis very thick, extending nearly one third of its length beyond the plate (Figs. 4H). <b>Remarks:</b> The type locality is located at the Nangongshan National Forest Park, with altitude raging from 1700 to 2100 m. <b>Distribution:</b> China (southern Shaanxi Province).
