Crenitis (Crenitis) View in CoL sp.

( Figs. 42–49 View FIGURES 42 – 49 , 52 View FIGURES 50 – 55 , 63–66 View FIGURES 63 – 72 )

Material examined: CHINA: Yunnan: 1 male ( SYSU), CHINA: Yunnan Prov., Baoshan / City, Baihualing, Jiujiezi, 25°18′N 98 °47′E, 2016m / 19.iv.2015, Renchao Lin & / Yudan Tang leg.

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 View FIGURES 42 – 49 ). Mesoventrite with a transverse ridge ( Figs. 49 View FIGURES 42 – 49 , 64 View FIGURES 63 – 72 ). Metafemora glabrous ( Figs. 43 View FIGURES 42 – 49 , 66 View FIGURES 63 – 72 ), with pubescence on extreme base ( Fig. 66 View FIGURES 63 – 72 ). 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 View FIGURES 50 – 55 ).

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.
