MATERIAL. Holotype and GoogleMaps paratype, 2♂♂ ( ZISP), labelled: ‘ NAMIBIA: Kavango Pr.,/ Shamwura Rest Camp ,/ 130 km E Rundu, 1090 m,/ 18.0262º S 20.785096º E,/ 13–31.XII. [20]13. S. Murzin lg.’. Aedeagus examined in the males. GoogleMaps

DIAGNOSIS. A slender, medium-sized, African species having pronotal base sparsely punctate outside basal sulci, elytra long, parallel-sided, with rather rounded humeri; profemur with a large tubercle at middle of posteroventral margin. Of the African and Madagascan congeners, H. rufus ( Chaudoir, 1876) is much larger, with BL 5.5 mm, while both H. africanus Tschitschérine, 1898 and H. madagascariensis Tschitschérine, 1900 , have the pronotum differently shaped due either to the apex subtruncate or to the base nearly as wide as the elytral bases combined. For differences of H. sinuatus see its redescription above.

DESCRIPTION. As for the other reviewed species of the genus except as follows: Body slender ( Fig. 4 View Figs 1–5 ), BL 3.8–4.1 mm. Pronotum subquadrate, a third wider than long, PW/PL 1.32, two thirds wider than head, PW/HW 1.65–1.67, broadest two fifths from apex, PLw/PL 0.61–0.63. Sides rounded, subsinuate a fourth from base. Base a third wider than apex, PB/PA 1.30–1.33, slightly trisinuate and slightly oblique in lateral thirds. Apical angles a little projecting, apical bead imperceptible. Elytra long, EL/EW 1.60–1.63, EW/PW 1.25– 1.28; either intervals 6 and 8 or 7 and 8 confluent before apex, or 8th reaching apex. Profemur modified in male, ventrally with a posteroventral carina conspicuously dilated at middle in form of a wide blunt tooth ( Fig. 8 View Figs 6–10 ). Protarsomeres 1–3 moderately dilated in male.

Aedeagus ( Figs 15–16, 19, 25–26 View Figs 11–28 ) as in H. sinuatus , except that apex of median lobe in ventral view is slightly shorter and subtriangular rather than obtrapezoidal.

NAME. Refers to the slender body, with long elytra.
