DIAGNOSIS. See the redescription.

REDESCRIPTION. Hardly different from H. ferrugineus in the following characters ( Fig. 5 ): BL 4.3 mm. Pronotum slenderer and narrower, PW/PL 1.37, PW/HW 1.66, with base barely narrower, PB/PA 1.41, and prebasal sinuation of lateral margin longer; PLw/PL 0.59. Pronotal apical bead imperceptible. Elytra similar, EL/EW 1.51, EW/PW 1.27; intervals 6 and 8 confluent before apex. Profemur modified in male, ventrally with a small yet distinct tubercle a third from base and posteroventral carina (with which ventral groove is limited posteriorly) conspicuously dilated at middle in form of a wide blunt tooth ( Fig. 7 ). Protarsomeres 1–3 only slightly dilated in male.

Aedeagus ( Figs 13–14, 18, 23–24 ): median lobe in lateral view curved at a slightly obtuse angle; apex lamellate, in ventral view wide obtrapezoidal, rather widely rounded apically.
