Description
Summary:The nudibranch Charcotia granulosa , described originally by Vayssière (1906) from one specimen, was recollected for the first time at Signy Island, Antarctica. These three specimens allow a redescription of the morphology, anatomy and histology. The synapo-morphies of the Charcotiidae (narrow, glandular stripe on the rightside starting behind the female genital opening, and running posteriorly above the nephroproct and anal papilla, and flat, rudimentary lateral radular teeth), with the two genera, the monotypic Charcotia Vayssière , 1906 and Pseudo-tritonia Thiele, 1912 (with three species) are discussed.
