In males, the base of the aedeagus is asymmetric, more or less acutely drawn out, directed towards the right and fused with the parameres.

[6] Most larvae of Amarygmini have a regular, oval excavation on the ninth abdominal tergite.

[5] Like other beetles, Amarygmini go through complete metamorphosis with the life stages of egg, larva, pupa and adult.

They occur in both natural (e.g. primary and secondary forests) and artificial (e.g. street trees, parks, gardens) habitats.

Some species of this genus are believed to be scavengers or predators, based on the presence of arthropod fragments in their guts.
