Diagnosis. Pronotum metallic green to metallic coppery. PW/PL = 1.14-1.26; PAW/PBW = 0.76-0.92 (Fig. 22 ); pronotum subquadrate with anterior angles rounded, not projected forward; disc gently convex, sparsely punctate. Elytral intervals convex basally, flat apically, densely punctate and pubescent. Hind wings developed. Metepisterna long, MW/ML = 0.75-0.92 (Fig. 14 ). Distal half of femora red-brown, the rest of legs black. This species is similar to Chlaenius (Haplochlaenius) costiger Chaudoir, 1856, but intervals interval convex basally and flat apically, not costulate. Figures 17-24.

Head, elytra, and venter black; pronotum metallic green to metallic coppery; antennae, labial and maxillary palpi, apex of mouthparts and tarsomeres dark brown; distal half of femora red-brown, the rest of legs black. Head . Vertex finely punctate and pubescent, with a glabrous area in the middle; antennae long, reaching middle of elytra; antennomere 3 ~ 1.7 x longer than antennomere 4. Pronotum subquadrate, PW/PL = 1.14-1.26 (Fig. 22 ), widest at apical four-ninth; anterior margin slightly concave, PAW/PBW = 0.76-0.92; lateral margins rounded or straight before posterior angles; anterior angles rounded, not projected forward; posterior angles obtuse; disc gently convex, sparsely punctate, without glabrous area in the middle; median line distinct, fine, reaching anterior margin and base; basal foveae deep, punctate and pubescent.

(Sphodromimus) deuvei (Morvan, 1997) (Guangxi, Huaping) A apical lamella B left lateral view C dorsal view D ventral view E right lateral view. Left scale bars: 0.5 mm ( A ); right scale bars: 1.0 mm ( B-E ). Elytra elongate, EL/BW = 1.47-1.83; slightly convex, widest near posterior third, rounded at apex in males, subtruncate in females; parascutellar striae well developed; parascutellar pores present; striae with deep punctures; interval convex basally, flat apically, densely punctate and pubescent; sutural angles obtuse; hind wings developed. Venter densely punctate, pubescent; metepisterna (Fig. 14 ) long, MW/ML = 0.75-0.92; abdominal sternites III-VI with one setiferous puncture each side, sternite VII with one pair of setiferous punctures in males, two pairs in females. Legs long and slender; tarsi nearly smooth dorsally. Male genitalia . Median lobe (Fig. 30B-E ) large, long, strongly bent to ventral side; apical orifice opened dorsally, long and wide, not reaching basal bulb; in dorsal view, apical lamella (Fig. 30A ) slightly bent to left side, width slightly longer than length, apex rounded; in left lateral view, apical portion slightly bent ventrally at apex, left side near apical lamella with a large denticulation; internal sac with flagellum slender, apex with a helical sclerite, not reaching to apical orifice; left paramere larger than right paramere, both rounded; endophallus with flagellum fine and slightly bent; basal part of flagellum without a sclerite; apical part of flagellum with a drop-shaped bursa.

(Sphodromimus) flavofemoratus Laporte, 1834 (Yunnan, Menglun) A apical lamella B left lateral view C dorsal view D ventral view E right lateral view. Left scale bars: 0.5 mm ( A ); right scale bars: 1.0 mm ( B-E ). Female genitalia . Bursa copulatrix (Fig. 38A-C ) very long, base with trapeziform protrusion; villous canal long, tortuously contorted, adhered to common oviduct; spermatheca and spermathecal gland absent. Distribution. (Fig. 40 ) China (Fujian; Guangdong; Guangxi; Guizhou; Hainan; Hong Kong; Yunnan), Indonesia, Laos, Myanmar, Vietnam. Remarks. Due to the fully developed hind wings and the shape of pronotum, this species is very special among species of Sphodromimus . It also has a wider distribution than other species. But the morphological characteristic of the apical lamella of the aedeagus, denticulate on the dorsal side, and the mentum with a bifid tooth show that the species belongs to Sphodromimus . The subspecies C. (Sphodromimus) flavofemoratus enleensis Mandl, 1992 was upgraded as a valid species (see below).
