Diagnostic Notes
The tribe Apatini is characterised by:

- Hind coxae contiguous or closely approximated

- Pronotum hood-like; head deeply inserted into the pronotum underneath, head not entirely visible from above

- Pronotum with posterolateral carina but carina not present along entire lateral margin

- Tarsal segment 1 shorter than segment 2 and segment 3 also shorter than segment 2

- Antennal club segments 1 and 2 cup shaped and strongly transverse

The genus Apate is characterised by:

- Body length: 5.5-32.0mm

- Elytra dorsal apical end with 2-3 prominent ridges

- Apical declivity abruptly truncated and armed with 2 or 3 pairs of projections

- Clypeus anterior margin not concave and usually with a single toothlike, smooth triangular projection in the middle.

There are 15 known valid species in this genus.

Genus Sex determination:

- Pronotum with anterior angles with a hooked tooth (Males), unarmed (Females)

- Antennal club segments without pits (Males), pitted (Females)

- Frons without a crown of brush or hair (Males), with a brush or hairs (Females)

Diagnostic characteristics of this species include:

Female:

- Body length: 13.0-22.0mm

- Frons not granulose but with a brush of fine hair

- Dorsal view of elytra distinct along entire length and terminating in raised and toothlike prominences on the anterior margin of the apical declivity

- Punctation of elytra indistinct

- Sutural angle of each elytron spinelike

Male:

- Body length: 13.0-22.0mm

- Elytra sculpturing composed of irregular depressions with 1 t0 3 deep punctures at the bottom, interspaces look varicose

- Granules in the middle of the vertex larger than the lateral one

- Rim of apical border of apical declivity not narrowing towards the sutural angle of each elytron
