Diagnostic Notes
The tribe Bostrichini is characterised by:

- First and second antennal club segments not cup-shaped, more or less compressed laterally or flabellate

- Hind coxal cavities completely or incompletelty margined by a sharp raised ridge along the anterior margin of the first visible abdominal sternite.

The genus Bostrychopsis has 23 known species and is characterised by:

- Body length: 6.0-21.0mm

- Antennae 10-segmented, funicle 5-segmented

- Frons of both sexes uneven: more or less distinctly raised close along the anterior margin and depressed, impressed or flattened behind the eyes

- Females often with a hump or a large raised transverse process in the middle of the frons.

Bostrychopsis trimorpha is characterised by:

- Body length: 8.0-14.0mm

- Marginal groove of elytra stopped at the outer turning point

- Funicle distinctly shorter than the scape and pedicel

- Scape bare but pedicel with a dorsal tuft of rather long hairs
