H. Wagele et al., REDESCRIPTION OF CHARCOTIA-GRANULOSA VAYSSIERE, 1906 (NUDIBRANCHIA, ARMINOIDEA, CHARCOTIIDAE) FROM SIGNY ISLAND, ANTARCTICA, Journal of molluscan studies, 61, 1995, pp. 197-207
The nudibranch Charcotia granulosa, described originally by Vayssiere
(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 Charcot
iidae (narrow, glandular stripe on the right side starting behind the
female genital opening, and running posteriorly above the nephroproct
and anal papilla, and flat, rudimentary lateral radular teeth), with t
he two genera, the monotypic Charcotia Vayssiere, 1906 and Pseudo-trit
onia Thiele, 1982 (with three species) are discussed.
