Diagnosis

6.0–7.2 mm long (mean = 6.86 mm; n = 5); 1.8−1.9 times as long as wide. This species can be distinguished by its larger size; elytralelytral:
pertaining to the elytra
declivitydeclivity:
downward slope of either the pronotum or elytra
strongly impressedimpressed:
a depression in a surface
, sides of impression raised and bearing tuberclestubercle:
a small knob-like or rounded protuberance of the exoskeleton
or rugosities; and elytralelytral:
pertaining to the elytra
impression bearing fairly sparse, long hairs or short hairs only.

This species is most similar to H. comans, from which it can be distinguished by the strongly impressedimpressed:
a depression in a surface
declivitydeclivity:
downward slope of either the pronotum or elytra
rather than the declivitydeclivity:
downward slope of either the pronotum or elytra
plano-concave from suture to interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
