Adult diagnosis.
The species can be distinguished by a combination of following characters: 1) head and clypeus fully clothed by pubescence; 2) femora fully pubescent; 3) elytra with dense pubescence, not arranged in stripes; 4) aedeagus with rod-like sclerite; 5) parameres moderately asymmetrical.
Adult diagnostic description.
Male. Colour: Body (Figs 2d View Figure 2 , 3d View Figure 3 ) dark brown; coxae, trochanters, femora, tibiae, and tarsi brown; tarsal claws pale brown with reddish tincture. Pubescence: Head and clypeus fully clothed with short, prone pubescence, most densely set behind eyes, and with numerous slightly longer, curved, semi-erect, hair-like setae. Pronotum (Fig. 6d View Figure 6 ) covered by a short, moderately dense, prone pubescence, and with moderately long, curved, semi-erect, hair-like setae. Elytra with densely arranged, short, recumbent pubescence, and numerous moderately long, curved, semi-erect, hair-like setae. Femora, pro- and metatibiae densely covered with moderately long, recumbent, hair-like setae; mesotibiae with pubescence only at extreme base. Metaventrite densely clothed with short, prone pubescence. Surface: Head and clypeus sparsely microreticulate, concealed by pubescence. Pronotum densely punctate, partly concealed by pubescence. Elytra with rows of punctures shallowly impressed; intervals nearly flat. Prosternal process (Fig. 7d View Figure 7 ) subparallel between procoxae, then subtriangular with rounded apex. Aedeagus (Figs 14a-c View Figure 14 ) with long, dorsal, rod-like sclerite on penis; parameres asymmetrical, left one slightly longer. - Female unknown.
