Euphrosinopsis antipoda Kudenov, 1993. Diagnosis (after Kudenov (1993) ). Prostomium with five appendages, including median antenna, two lateral antennae, and two palps. No prostomial eyes, with one pair of eyes deeply embedded lateral to median antenna. Caruncle free from the body wall for most of its length. Remarks. The genus Euphrosinopsis is currently endemic to Antarctica and has been established to accommodate three known Antarctic species ( Kudenov 1993 ): E. antarctica ( Hartmann-Schroeder & Rosenfeldt, 1992), E. crassiseta Kudenov, 1993, and E. horsti Kudenov, 1993. It is similar to Euphrosinella in having five prostomial appendages and reduced fusion of caruncle to the body wall. The main difference from both Euphrosine and Euphrosinella considered by Kudenov (1993) was the lack of prostomial eyes and presence of large, deeply embedded eyes positioned laterally to median antenna.
