- Anterior margin of pronotum truncate, concave or deeply emarginate

- Lateral teeth more prominent than median teeth.

The genus Heterobostrychus is defined by:

- Body length: 5.0-16.0mm

- Head capsule not deeply and transversely constricted behind eyes

- Gena without a large tooth or lobe below each eye

- Pronotum excavated behind the middle of the anterior margin.

There are 5 known species in Heterobostrychus: H. aequalis, H. brunneus, H. hamatipennis, H. pileatus and H. unicornis.

- Apical declivity and elytra pubescent

- Antennal club 2.0x as long as funicle

- Second segment and last segment of hind tarsus subequal
