Diagnosis.

Antennomere 1 coniform ( Fig. 59 View Figures 52–65 ); antennomeres 1-3 brown; intervals 1-5 glabrous medially with one row of pubescence laterally near striae ( Fig. 87 View Figures 80–93 ); apical lamella of aedeagus moderately rounded ( Fig. 131 View Figures 131–145 ), thin and moderately reflexed in lateral view ( Fig. 132 View Figures 131–145 ).

Description.

Total length = 16.00-17.00 mm (mean = 16.4), width = 5.33-6.13 mm (mean = 5.68); HW = 2.70-2.95 mm (mean = 2.80), EYL = 1.00-1.05 mm (mean =1.01), ratio Ant3/Ant1 = 1.42-1.65 (mean = 1.52), PL/PW = 0.78-0.80 (mean = 0.79), EL/EW = 1.74-1.90 (mean = 1.80), EL/ PL= 1.37-1.47 (mean = 1.41).

Head and pronotum black with green and coppery metallic luster; elytra black; ventral surface black; antennomeres 4-11, trochanters, palpomeres, and tarsomeres dark brown; antennomeres 1-3, femora, tibiae yellow to brown.

Head with vertex sparsely pubescent and coarsely punctate behind eyes; antennomere 1 coniform ( Fig. 59 View Figures 52–65 ); labrum nearly truncate at apex. Pronotum with disk nearly smooth, very sparsely punctate near midline in a few specimens; basal foveae narrow, deep, sparsely punctate, pubescent. Elytra with intervals convex, glabrous medially, pubescent laterally ( Fig. 87 View Figures 80–93 ), intervals 6-9 densely pubescent; striae deep, punctate; humeral angle obtuse ( Fig. 73 View Figures 66–79 ). Abdominal sterna IV-VI nearly glabrous medially, sternum VII narrowly rounded at apex (107-108). Aedeagus stout ( Fig. 132 View Figures 22–27 ), lamella rounded at apex ( Fig. 131 View Figures 66–79 ), thin and slightly bent ventrally ( Fig. 132 View Figures 66–79 ).

Geographical distribution.

Fig. 158 View Figure 158 . Known from Shaanxi, Gansu, and Hubei Provinces, China.

Remarks.

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

Chlaenius wrasei was first described as a subspecies of Chlaenius noguchii by Kirschenhofer. Later ( Kirschenhofer 2005), he upgraded this taxon to status as a distinct species. We agree with this decision, given that the pubescent elytral intervals 6-7 of adults and stout aedeagus of males are very different from those of Chlaenius noguchii .

Members of Chlaenius wrasei are similar to those of Chlaenius leishanensis in having antennomere 1 coniform and pronotum nearly impunctate, but differ from the latter in having intervals 1-5 wholly glabrous medially (only the basal portions of these intervals are glabrous medially in Chlaenius leishanensis ), tibiae concolorous with femora (tibiae much darker than femora in Chlaenius leishanensis ), and lamella of aedeagus thin and less bent ventrally (thickened and more markedly bent in Chlaenius leishanensis ).
