Diagnosis. Male body length 8.0– 9.5 mm, width 2.5–2.8 mm; female body length up to 12.0 mm, width up to 3.2 mm (Gurjeva 1989). Body black, antennae and legs lighter (Figs. 6A–C). Pronotum with distinct but sparse punctures, hind angle slightly divergent and narrowed, apex sub-acute, with a distinct carina. Scutellum elongate, widest at anterior margin, narrowest at middle, round posteriorly. Elytra with deep striae. Male genitalia as Figs. 7E, 8D, penis thin, apex robust and long, paramere with lateral margin curved, strong concave distally, apex round, the hook blunt; female genitalia as Figs. 9A–B, ovipositor with small styli, spines in central part of bursa copulatrix large.
Remarks. This species is very close to H. inunctus (Lacordaire), but can be distinguished from the latter by possession of the following characteristics: 1) body black, legs and antennae brown to dark brown, with body usually bicolored (elytra usually lighter than the rest of the body, or distinctly reddish brown) in H. inunctus; 2) antennomere 3 cylindrical, barely broadened at apex, clearly narrower than antennomere 4, with antennomere 3 conical, clearly broadened at apex, slightly narrower than antennomere 4 in H. inunctus; 3) prosternum and hypomeron with sparser punctation, while denser in H. inunctus; 4) the apex of the paramere is rather narrow and with blunt hook while the apex of the paramere more expanded and with sharp hook in H. inunctus.; 5) female with larger styli in the ovipositor, and with the spines in the central part of the bursa copulatrix large, in H. inunctus the styli are very small, and the spines in the central part of bursa copulatrix are small.
Distribution. North and South Caucasus (Cate et al. 2007).
Natural history. Individuals have been collected from leaves in the montane forest (Figs. 11B–C).
