The genus Asteromorpha Lutken (Echinodermata: Ophiuroidea: Euryalidae: Euryalinae) is revised based on 52 specimens, including six syntypes of Asteromorpha steenstrupi, one syntype of Asteromorpha perplexum (Koehler), one syntype of Asteromorpha koehleri (Doderlein) and the holotype of Astroschema capensis Mortensen. We propose a new combination of Asteroschema capense (Euryalidae: Asteroschematinae) with the genus Asteromorpha. Consequently Asteromorpha includes four species: A. capensis, A. koehleri, A. rousseaui, and A. tenax. These four species are all redescribed. A taxonomic key to the species of the genus Asteromorpha is also provided.
