Diagnosis.

Antennomere 1 coniform ( Fig. 57 ); color of antennomere 1 lighter than other antennomeres; basal half of intervals 1-5 glabrous medially, with pubescence laterally ( Figs 26 , 85 ); lamella of aedeagus rounded at apex ( Fig. 127 ), thickened and bent ventrally ( Fig. 128 ).

Description.

Total length = 15.00-18.00 mm (mean = 16.50), width = 5.33-6.13 mm (mean = 5.78); HW = 2.55-3.00 mm (mean = 2.79), EYL = 0.95-1.10 mm (mean = 1.04), ratio Ant3/Ant1 = 1.53-1.73 (mean = 1.62), PL/PW= 0.80-0.89 (mean = 0.86), EL/EW = 1.64-1.89 (mean = 1.76), EL/ PL = 1.26-1.46 (mean = 1.35).

Head and pronotum black, with green or coppery metallic luster; elytra black; ventral surface black; antennomeres 2-11, palpomeres, trochanters, tibiae, and tarsomeres dark brown to black; antennae and femora yellow to light brown.

Head with vertex coarsely punctate and pubescent behind eyes; antennomere 1 coniform ( Fig. 57 ); clypeus and labrum slightly emarginate at apex. Pronotum with disk smooth in most specimens, but sparsely punctate along middle line in a few specimens; basal foveae small, deep, pubescent, very sparsely punctate. Elytra with basal half of intervals 1-5 smooth and glabrous medially, pubescent laterally ( Figs 26 , 85 ), intervals 6-9 and apical portion of intervals 1-5 densely pubescent; striae deep, punctate; humeral angle rounded ( Fig. 71 ). Abdominal sterna IV-VI sparsely pubescent medially, densely pubescent laterally, apex of sternum VII rounded in male ( Fig. 103 ), nearly truncate in female ( Fig. 104 ). Aedeagus stout, lamella rounded at apex ( Fig. 127 ), thickened and bent laterally ( Fig. 128 ).

Geographical distribution.

Fig. 158 . Known from Guangxi, Guizhou, Chongqing and Hubei Provinces, China.

Remarks.

Mensural data cited in the description were obtained from all cited specimens.

Males of this species ( Fig. 128 ) are similar to those of Chlaenius formosensis ( Fig. 126 ) in form of the aedeagus in lateral view, but differ from the latter in having the lamellar apex rounded ( Fig. 127 ; nearly truncate in Chlaenius formosensis , Fig. 125 ). Both males and females of Chlaenius leishanensis have elytral intervals 6-7 densely pubescent throughout, whereas Chlaenius formosensis adults have those intervals glabrous medially.
