Diagnosis
Body (
Fig. 1C–D
) brown, slender, elongate-oval, completely covered with moderately dense short (
H. vernus
) or long (
H. primaeveris
) longitudinally striated scales, sparse scale-like and simple setae (
Fig. 10
). Body length
7–12 mm
. Eyes small circular, moderately convex in dorsal view; surface behind eyes concealed under anterior margin of pronotum.
Pronotum weakly transverse (1.4 × as wide as long). Anterolateral angles not expressed. Prosternum without transverse triangular depression along anterior margin. Prosternal process short and narrow

(length 1.7 × width), not raised above procoxae, not protruding. Prosternum very short, near 2 × as long as longitudinal diameter of one procoxa.
Elytra elongate-oval (
H. vernus
) or triangular, almost wedge-shaped (
H. primaeveris
). Scutellar shield completely (
H. vernus
) or partially concealed (
H. primaeveris
) by elytral base; surface around scutellar shield without triangular depression. Transverse length of one metacoxa less than intercoxal process of abdominal ventrite 1 (
Fig. 1D
).
Trochanters with very short dense setae. Meso- and metafemora curved outward along elytral lateral vertical side. Pro- and metatibiae weakly curved outward, protibiae (
Figs 26A
,
27E
) widened at apex, outer margin of protibia projecting into short rounded process at apex with one (
H. primaeveris
) or several acutely angulate and closely located (
H. vernus
) short spines; outer margin armed with very short tubercles with long and thin spines and additionally with long and sparse setaesetae (
Fig. 27E
). Protibial terminal spurs strongly elongated, extending to base of protarsomere 5, mesotibial terminal spurs extending to base of mesotarsomere 3, metatibial terminal spurs extending to midlength of metatarsomere 1. Outer and inner protibial terminal spurs subequal in length, inner meso- and metatibial terminal spurs longer than outer one; spurs flattened, outer spur moderately narrowed to apex, acutely angulate at apex. Protarsi laterally not flattened, covered with short strong setae. Meso- and metatarsi flattened from sides, covered with long fine setae dorsally and shorter and stronger setae ventrally. Tarsal claws elongated, thin, weakly curved outward.
Male genitalia
Male genitalia identical to those in
Apatopsis
.
Ovipositor
(
Fig. 15J–L
) Very short, paraproct slightly longer than coxite. Paraproct with thin baculi, indistinct at apical third.
Coxite lobe baculi short, more sclerotized in apical part, with additional sclerotized projection on ventral side; lobe II very narrow (
Fig. 15L
); lobe III slightly longer, conical, without additional projecting apical processes; lobe IV membranous, conical, rounded at apex, densely pubescent with long setae.
Female genital ducts
Destroyed during preparation.
