摘要

摘要Marion Dufresne号油轮的MD55巡航是法国和巴西的一次重要探险，致力于探索巴西东南海岸的浅海和海底生物。在巡航过程中，对属于Ischnochitonidae Dall（1889）和Acanthochitonidae Pilsbry（1893）科的四种多鞭毛虫进行了采样，并对其进行了研究。我们尽可能将材料与原始说明和凭证材料进行比较。据报道，Stenoplax marcusi（Righi，1971）、Acanthochitona ciroi Righi（1971）和A.terezae Guerra Junior（1983）的范围扩大。Acanthochitona Gray的一个新种，1821年被描述为Acanthochetona oxum n.sp.。它与其他西大西洋同类的不同之处在于存在圆形到椭圆形的被盖脓疱和插入板的直外缘。

Taxonomic study on the Polyplacophora (Chitonida: Ischnochitonidae et Acanthochitonidae) collected by the Marion Dufresne (MD55) expedition, with description of a new species

ABSTRACT The MD 55 cruise of the R/V Marion Dufresne was an important French-Brazilian expedition devoted to the exploration of the shallow offshore waters and benthos off the south-eastern coast of Brazil. Four polyplacophoran species belonging to the families Ischnochitonidae Dall, 1889 and Acanthochitonidae Pilsbry, 1893 were sampled during the cruise and are studied herein. We compare the material with the original descriptions and voucher material whenever possible. Range extensions are reported for Stenoplax marcusi (Righi, 1971), Acanthochitona ciroi Righi, 1971, and A. terezae Guerra-Junior, 1983. A new species of Acanthochitona Gray, 1821 is described, Acanthochitona oxum n. sp. It differs from other Western Atlantic congeners by the presence of round to oval tegmental pustules and the straight external margin of the insertion plate.
