 Colour (Fig. 53). Body reddish brown with head, thorax, and basal and apical elytra darker. Head, pronotum and elytra covered with fairly dense, more or less evenly distributed, whitish pubescence; pubescence on elytra generally shorter.   
 Head. Postclypeus subtriangular and flattened, with fairly dense coarse punctures; frontoclypeal suture deep and wide in middle; distance between lower lobes of eyes 1.8 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 1.25 × as long as distance between eyes on ventral side; genal length 0.19 × as long as head width immediately below eyes. Antennae largely damaged.   
 Thorax and abdomen. Pronotum 0.94 × as long as width, rounded with a small process at each side; posterior margin 1.22 × as wide as anterior margin; pronotal disc without distinct nodules in middle area; disc and side strongly rugose transversely. Scutellum semicircular, with sparse pubescence. Elytra 5.26 × as long as prothorax and 3.44 × as long as shoulder width; basal 1/3 with coarsely punctures; apex more or less rounded at margin and with a small spine at suture. Apex of terminal sternite rounded or slightly truncate.   
 Male terminalia. Apex of ventral median lobe emarginate and apex of dorsal lobe with rounded; ventral lobe distinctly longer than dorsal lobe; spined region of internal sac divided into two sections; first section with sparse short simple spines on sides near base; second section with fairly dense long simple spines; unspined gap between first and second section above as long as second section (Fig. 91a). Eighth sternite rounded at side, shallowly emarginate at apex, with long and fairly long setae arising terminally; ventral surface with sparse cloud-like processes (Fig. 91b). Eighth tergite rounded at apex, with fairly dense simple spines and multi- branched spine on surface (Fig. 91c). Paramere long, 2.5 × as long as wide, cylindrical in shape, apex rounded with long and short setae (Fig. 91d).

 This species differ from others species of Uracanthus in having very short genal length; pubescence on the elytra uniform without any line or stripe of denser pubescence. No other specimen matches the type.
