Abstract

Two new species of the subgenus Asteroporpa (Asteromoana) (Echinodermata: Ophiuroidea: Euryalida: Gorgonocephalidae) are described from southwestern and southern Japan. A. (Asterom.) muricatopatella sp. nov. has only cone-shaped dermal ossicles with terminal projections on radial shields, only plate-shaped dermal ossicles on oral plates, and coneshaped dermal ossicles with relatively short terminal projections at the lateral interradial disc. A. (Asterom.) koyoae sp. nov. has both cone-shaped dermal ossicles with terminal projections and plate-shaped dermal ossicles on radial shields, cone-shaped dermal ossicles with terminal projections on oral plates, and cone-shaped dermal ossicles with relatively long terminal projections on the lateral interradial disc. A taxonomic key to all four species of the subgenus A. (Asteromoana) is provided.
