Description.
Holotype male (Figs 3 View Figures 1–6 , 4 View Figures 1–6 ). Body length 9.7 mm; width across humeri 6.0 mm. Dorsum moderately shiny. Head, pronotum and scutellum dark brown with elytra reddish brown. Head (Fig. 12 View Figures 11–16 ): labrum with anterior margin crenulate, disc transversally rugose. Clypeus trapezoidal, surface densely rugopunctate; protrusion at basal angle moderately developed. Clypeofrontal suture well defined, distinctly curved in front of frontal tubercle. Frons with surface sparsely punctate, punctures fine, frontal tubercle vertically located in junction of suture, right-triangle in shape in lateral view. Eye prominent, canthus simple, not exceeding eye. Thorax: pronotum (Fig. 18 View Figures 17–22 ) quadrituberculate, tubercles placed in a line, lateral tubercle greatly reduced in size; anterior face of median tubercles almost perpendicular to plane of pronotum; primary punctures coarse, moderately distributed on disc and intermixed with impunctate area, punctures between lateral margins of pronotum and fovea bigger and denser, posterior area between elytral humeri and suture impunctate except for four coarse punctures in front of scutellum, secondary punctures tiny, evenly scattered throughout surface of pronotum; frontal and lateral margins beaded, posterior margin beaded only in front of elytral humeri. Scutellum elongate, secondary punctures sparse throughout surface with a coarse puncture at center. Elytron (Fig. 24 View Figures 23–28 ): elytral striae shallow, punctures mostly spaced 2-3 times diameters of punctures. Intervals slightly convex including sutural one, surface with scattered secondary punctures. Male genitalia (Figs 31 View Figures 29–38 , 32 View Figures 29–38 , 40 View Figures 39–43 ).
Female (Figs 46 View Figures 44–51 , 47 View Figures 44–51 ). Body length 7.7-10.0 mm; width across humeri 5.4-6.5 mm. Similar to male with minor differences in the form of strongly wrinkled surface of clypeus, transverse frontal carina trilobed, central lobe more prominent than lateral lobes, punctures on frons and vertex rugose, transverse pronotal carina feebly bilobed with lobes broadly developed, punctures on pronotal disc coarser and denser than males.
Variation in male. Dorsum brown, smaller body size, 6.6 mm in length and 5.2 mm in width across humeri, frontal tubercle less developed and not in junction of clypeofrontal suture, pronotal tubercles feebly convex, and number of coarse punctures arranged at pronotal posterior margin variable.
Diagnosis.
Bolbelasmus chifengi is morphologically similar to B. concavisuturalis , but can be distinguished from the latter by the coarser and denser primary punctures on the pronotal disc (finer and scattered in B. concavisuturalis ), elytral intervals evenly convex (elytral intervals flat with sutural interval concave in B. concavisuturalis ) and by the longer parameres (shorter in B. concavisuturalis ).
Distribution.
Southern Yunnan, China (Fig. 52 View Figure 52 ).
Etymology.
Bolbelasmus chifengi sp. nov. is named after Dr Chi-feng Lee, the curator of the Department of Applied Zoology, Taiwan Agriculture Research Institute, Taichung, Taiwan, who kindly provided materials used in this study.
