Figures 31–41

Description. Male: Pronotum length×width 2.5× 3.1mm, tegmen length 10.5 mm, body length (including tegmen) 12.5 mm. Body blackish brown. Vertex brown with testaceous band. Occiput region pale yellow. Antennal base yellowish brown, remainder of antenna dark brown. Apex of fourth and fifth maxillary palpomeres blackish brown. Pronotum yellowish brown with blackish brown U-shaped maculae ( Fig.32 ). Tegmina blackish brown, basal and apical part paler brown. Vertex with interocular space distinctly narrower than the distance between antennal sockets, with one transverse band between eyes ( Fig. 31 ). Third and fifth maxillary palpomeres about same length, each distinctly longer than the fourth ( Fig. 32 ). Tegmina with discoidal sectors longitudinal. Hind wings with costal vein thickened distally, radial vein straight and unbranched; medial and cubital vein distinctly curved near middle, medial vein simple, unbranched, cubital vein with 3 complete branches and 2 incomplete branches, apical triangle small ( Fig. 33 ). Front femur Type B 3 ( Fig. 34 ). First abdominal tergum with one group of setae in middle ( Fig.35 ); seventh abdominal tergum with two depressions near anterior margin, lateroposterior angles produced into round protuberance ( Fig.36 ). Male genital supra-anal plate in ventral view nearly symmetrical with some slender setae and minute teeth, hind margin sinuously produced into two long, spine-like processes directed laterad and with rounded knob between them ( Fig. 37 ). Paraprocts asymmetrical, in ventral view the right irregular with some slender setae, hind margin with three minute teeth near apex; left paraproct irregular, robust and bifurcate ( Fig. 37 ). Subgenital plate in dorsal view nearly symmetrical, lateral margins rounded, posterior margin slightly convex with two styli, each curved and bifurcate apically, the right arising from a distinct incision ( Fig. 38 ). Left hook-like phallomere with distal part stout ( Fig. 39 ); median phallomere sticklike and shallowly curved, long and slender with acute apex, appendage absent ( Fig.40 ); right phallomere reduced, irregular, sclerotized plate with slender base and swollen apex, and with one S-shaped appendage ( Fig. 41 ).

Material examined. Holotype ♂, China, Yunnan, Xishuangbanna, Puwen , 8 July 2004, coll. Xu Xiangrong. Paratypes: 8 ♂, Yunnan, Xishuangbanna, Mengla , 16 July 2004, coll. Wang Zongqing ; 1 ♂, 1 ♀, Yunnan, Xishuangbanna, Menglun , 12 July 1957, coll. Wang Zongqing ; 1 ♂, Yunnan, Xishuangbanna, Jinghong , 25 June 1958, coll. Zheng Leyi.

Remarks. This species is similar to S. spinosolobata , also known from Yunnan, China. However, it can be distinguished from the latter by: 1) first and seventh abdominal terga specialized; in S. spinosolobata seventh abdominal tergum unspecialized; 2) supra-anal plate in ventral view with some slender setae and minute teeth, hind margin sinuous and produced into two long, spine-like processes directed laterad and with a rounded knob between them; in S. spinosolobata hind margin of supra-anal plate broadly rounded; 3) subgenital plate in dorsal view with lateral margins deeply sinuate, posterior margin distinctly convex with two different styli; in S. spinosolobata subgenital plate trapeziform, transverse, hind margin slightly rounded.

Etymology. The specific epithet pyrrhocephalus references the reddish vertex of this species.
