A taxonomic review of the genus Astrodia (Echinodermata: Ophiuroidea: Asteronychidae)

  • Masanori Okanishi (a1) and Toshihiko Fujita (a2)
Abstract

The genus Astrodia (Echinodermata: Ophiuroidea: Asteronychidae) was revised based on 34 specimens including two syntypes of Asteronyx excavata, two syntypes of Asteronyx plana and two syntypes of Ophiocreas abyssicola. We proposed a transfer of Ophiocreas abyssicola (Euryalidae) to the genus Astrodia. Consequently, Astrodia now includes four species, Astrodia abyssicola, A. excavata, A. plana and A. tenuispina. These four species are all redescribed. A taxonomic key to the species of the genus Astrodia is also provided.
