Discussion.
The examined specimen has the following characters: length 2.8 mm, width 1.4 mm. Head blackish brown, pronotum and elytra dark brown. Head entirely with microsculpture. Pronotum with indistinct submarginal impression and more or less distinct submedian impressions, with strong microsculpture laterally. Pronotal punctures evenly distributed. Elytra with nine distinct series of punctures from base to apex (first series of punctures completely fused with sutural stria, only detected on basal third where sutural striae disappeared) (
Fig. 42
). Mesoventrite with a transverse ridge (
Figs. 49
,
64
). Metafemora glabrous (
Figs. 43
,
66
), with pubescence on extreme base (
Fig. 66
). Parameres broad, not incised laterally, with outer margin strongly curved subapically, more or less truncate apically. Median lobe gradually narrowed from base to anterior sixth, and then widened subapically, with a projection apically (
Fig. 52
).
Judging from the description of
Hebauer (1994)
, this specimen is most similar to
C. nepalensis
Hebauer, 1994
, a species which was not examined in this study. Therefore, the specimen is regarded as unidentified species.
