See text Herpetopoma is a genus of sea snails, marine gastropod molluscs of the family Chilodontaidae.

[2] In the past, this genus was often treated as a subgenus of Euchelus.

However, this genus may prove to be a composite taxon, given the diversity of the shell forms.

The operculum is multispiral as in a typical Trochus and with more, less rapidly expanding whorls compared with Euchelus.

[4] Species in this genus has typically two teeth, joined by a U-shaped notch, where the columella and the basal lips join.
