Body length 7.0–7.8 mm; head and pronotum reddish brown to dark brown, lateral explanate areas of pronotum paler; mouthparts, antennae and legs yellowish brown or reddish brown; elytra with luster, uniformly dark brown or disc somewhat reddish, in some specimens with a faint reddish patch on central area, the patch at most reaching 6th interval; ventral side yellowish brown to dark brown. Head glabrous, without punctures or microsculpture. Pronotum cordiform, widest near middle; ratio PW/PL 1.31 to 1.40; pronotal base briefly but distinctly lobed; disc glabrous, microsculpture indistinct, without punctures; front angles with a few setae, sometimes abundant and long (in specimens with additional interval setae), or sparse and short, but always distinctly longer than in Paraphaea binotata; lateral margins completely rounded in middle, sinuate before hind angles; front angles wide and rounded, not projected; hind angles rectangular or nearly so, slightly pointed; disc moderately convex; basal foveae wide and even, with a few punctures. Elytra with striae distinct, finely punctate along striae; intervals slightly convex, without punctures or microsculpture; 3rd interval with three or four setigerous pores, the apical one placed about apical one-eighth, adjacent to 2nd stria, position of the other two or three pores variable, pore number and position variable even in same specimen; 5th interval with one setigerous pore near base, adjacent to 5th stria; in some specimens, the odd intervals with some secondary setae; 17-19 umbilical pores on 9th interval. Male genitalia. Median lobe of aedeagus with apical third slightly expanded; in dorsal view, left-lateral margin moderately sinuate medially, and then gradually narrowed to apex; apical lamella placed in left-ventral side, narrowly triangular, apex rounded, slightly prolonged; internal sac with main flagellum sinuous; basal part of main flagellum moderately bent, trumpet-form expansion adjacent to left margin, apical margin of trumpet-form expansion not crenulate (Fig. 68). Female genitalia not studied.
