. ''Hoplitoides'' have early whorls which are grooved, then flat, and finally narrowly rounded venters; early stages with umbilical tubercles and space ribs, later stages becoming smooth.

''Hoplitoides'' has an established distribution which is widespread, from western North America, northwestern Africa and northern South America.
