Diagnosis.

Antennomere 1 cylindrical ( Fig. 60 ); antennomeres 1-3 yellow; intervals punctate, pubescent ( Fig. 88 ); lamella of aedeagus rounded at apex ( Fig. 133 ), thick in lateral view ( Figs 134-135 ).

Description.

Total length = 14.00-17.00 mm (mean = 15.10), width = 5.33-5.87 mm (mean = 5.60); HW = 2.40-2.85 mm (mean = 2.59), EYL = 0.95-1.00 mm (mean = 0.97), ratio Ant3/Ant1= 1.94-2.21 (mean = 2.08), PL/PW = 0.86-0.90 (mean = 0.88), EL/EW = 1.62-1.74 (mean = 1.68), EL/ PL = 1.30-1.39 (mean = 1.34).

Head, pronotum and elytra black, with blue or greenish blue metallic luster; ventral surface black; antennomeres 4-11, mandibles, palpomeres, trochanters, and tarsomeres brown; antennomeres 1-3, femora, and tibiae yellow.

Head convex, vertex punctate and pubescent behind eyes; antennomere 1 cylindrical ( Fig. 60 ); labrum slightly emarginate or truncate at apex; mentum tooth emarginate apically. Pronotum with disk convex, sparsely punctate and pubescent medially, more densely punctate along midline, near lateral margins, and near base; basal foveae deep, punctate and pubescent. Elytra with intervals convex, wholly punctate and pubescent ( Fig. 88 ), punctation and pubescence less dense in the basal half of intervals 1-4 than in other areas; striae moderately deep, punctate; humeral angle rounded or obtuse ( Fig. 74 ). Abdominal sterna IV-VI sparsely pubescent medially; apex of sternum VII narrowly rounded in male ( Fig. 109 ), slightly truncate in female ( Fig. 110 ). Apical lamella of aedeagus moderately rounded ( Fig. 133 ), thick in lateral view ( Figs 134-135 ).

Geographical distribution.

Fig. 158 . Known only from Sichuan and Yunnan Provinces, China.

Remarks.

Mensural data cited in the description were based on measurements obtained from 5 males and 5 females selected for maximum variation.

Members of this species are very similar to Chlaenius rambouseki in having the elytra wholly pubescent, but differ from the latter in having shiny elytral intervals (dull in Chlaenius rambouseki ), regular and uniform punctation on intervals (mixed large and small interval punctuation in Chlaenius rambouseki ), and thick apical lamella of aedeagus in males (thin in Chlaenius rambouseki males). In many Chlaenius agiloides members, the dorsal surface has a blue metallic luster rather than the green luster of Chlaenius rambouseki members.
