Diagnostic Notes
The subfamily Dinoderinae 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

- Pronotum anterior margin rounded or conical shaped or truncate

- Pronotum with medium tooth most prominent

- Head with plane or labrum angled downwards from a raised clypeus

- Tarsal segment 1 as long as or longer than segment 2; Segment 3 as long as or longer than segment 2

The genus Dinoderus is characterised by:

- Body length: 2.2-4.5mm

- Pronotum with posterolateral carina (in some species weakly developed)

- Elytra not more than 2.0x as long as pronotum

- Second antennal segment distinctly less than half as long as the first

There are 26 known species in this genus:

Diagnostic characteristics for D. minutus include:

- Body length 2.0-3.8mm

- Pronotum anterior marginal teeth: 6-8, conspicuously large, acutely rounded at the apices and distinctly separated, middle two more widely separated, slightly larger and sometimes with an extra smaller tooth between them

- Pronotum gradually widening from apex to base and with sides broadly rounded

- Hairs of apical declivity short, erect and may look yellowish

- Punctuation of disc of elytra nearly in longitudinal rows
