Revision of the Genus Austrodoris Odhner, 1926 (Gastropoda, Opisthobranchia)

Rich material from the Atlantic sector of the Antarctic Ocean allows a detailed description of the morphology and anatomy of Austrodoris kerguelenensis (Bergh, 1884) (Opisthobranchia, Nudibranchia, Doridacea). A comparison of type-material and specimens from former expeditions with new material indicates that the following species can be synonymized with Austrodoris kerguelenensis: Archidoris australis Bergh, 1884, Archidoris rubescens Bergh, 1898, Austrodoris crenulata Odhner, 1926, A. michaelseni Odhner, 1926, A. macmurdensis Odhner, 1934, A. nivium Odhner, 1934, A. tomentosa Odhner, 1934, A. mishu Marcus, 1985, and A. vicentei Marcus, 1985. Archidoris nivalis. Thiele, 1912 and Austrodoris granulatissima (Vayssière, 1917) are considered nomina dubia, since their holotypes are lost and the descriptions inadequate. Doris peculiaris Abraham, 1877 can not be assigned to the genus Austrodoris, as suggested by some authors.
