A genus of five species: A. martiana, widely distributed in Central America and NW pacific South America to N Ecuador; and four species endemic to each their small area in Venezuela and French Guyana.

Asterogyne, together with Welfia, Pholidostachys, Calyptronoma, Calyptrogyne and Geonoma, make up the group of geonomoid palms (tribe Geonomeae) characterised by having the flower groups sunken into pits in the inflorescence branches. Within that group, Asterogyne is distinguished by having the combination of flower pits covered by an immersed lower lip which rolls back at anthesis and stamens with free thecae borne on a bifid connective.
