Only two species in this group are normally found inland. Heterocerus fenestratus has the two orange marks on the elytra, each side of the suture, reaching the front margin of the elytra. In H. marginatus, the other inland species, these marks are absent so that the base of the elytra is entirely dark. Heterocerus fenestratus is very hairy and has heavily spined front legs used to excavate tunnels in mud.
