description: 4. Hemithyrsocera spinibarbis sp. nov.
Figs. 16–17, 56–67
Measurements (mm). Male, overall length including tegmina: 20.5–21.0; pronotum length × width: 4.0 × 5.0; tegmina length: 17.0–17.5.
Body blackish brown. Head black or blackish brown (Fig. 16). Occiput region pale yellow. Maxillary palpomeres blackish brown. Antennae blackish brown with base pale brown. Pronotum black with anterior and lateral margins yellow (Fig. 16, 58). Tegmina brown, subcostal zone brown or black. Legs brown. Abdominal terga and sterna blackish brown.
Vertex with interocular space slightly less than distance between antennal sockets (Fig. 56). The fourth and fifth maxillary palpomeres about same length, both weakly less than the third (Fig. 57). Pronotum nearly elliptical, the middle of hind margin distinctly produced (Fig. 58). Hind wing with narrow radius area, R1 with 5 branches, posterior branches of R extended before the base of anterior rami of radius and bifurcated at apical; MP simple, cubitus vein with two branches; apical triangle distinct. Front femur Type A3 (Fig. 59). Seventh abdominal tergum specialized with two medial, small, depressed and rounded specializations, setae present and lateral lobes absent (Fig. 62). Supra-anal plate (Fig. 63) in ventral view with hind margin rounded, right and left intercercal processes similar and straight, apices rounded with dense spines; right and left paraprocts dissimilar (Fig. 63), right one with clubbed and long process at anterior margin, left one nearly quadratic. Subgenital plate in dorsal view strongly asymmetrical (Fig. 64), hind margin with setose lobes or processes, some of which situating at the hind margin; single large stylus in right corner (Fig. 64).
Male genitalia. L3 (Fig. 65) long and slender, sclerotized portion small and without preapical incision; L2vm (Fig. 66) slender with base pointed, one long and slender accessory structure originating near apex, another huge, platelike and cleft accessory sclerite present; R2 (Fig. 67) simple and irregular. R3 (Fig. 67) with 2 obvious sclerites, one of which a long and slender sclerotisation with acute apex, the other nearly T-shaped with apices tapering or serrated.
Material examined. Holotype: ♂, China, Yunnan, Yingjiang County, 1–2 June 2008, leg. Zhang Weiwei.
Paratype: 1 ♂, same data as holotype.
Remarks. This species bears a close resemblance to Hemithyrsocera longiseta sp. nov. in shape and color, but differs from the latter in the following characteristics: 1) supra-anal plate with right and left intercercal processes, apices rounded with dense spines, but absent in the latter, 2) seventh abdominal tergum without lateral lobes, present in the latter, 3) L2vm slender with apex pointed, two accessory sclerites present, while in the latter, L2vm distally enlarged, apex broadly rounded with densely brush-like setae.
Etymology. The scientific name “ spinibarbis ” is from Latin, indicating apices of right and left paraprocts are scattered with lots of spinelike setae.
Distribution. China (Yunnan Prov.).
