Abstract

ABSTRACT Theta lyronuclea (Clarke, 1959), a North Atlantic deep-water species, is recorded for the first time from the southwestern Atlantic. This constitutes the first record of the genus and the second mention of the family Raphitomidae off Argentina. The samples were collected in the Mar del Plata Submarine Canyon on the Argentine Continental slope on board the R/V Puerto Deseado at 2,934 m depth in September 2013. Photographs of radulae, penises, and details of the ornamentation of the protoconch are provided. Detailed comparison of the specimens collected with the type material and several lots from northern Atlantic localities confirmed the identification.

西南大西洋深水中的北大西洋锥足目腹足目lyronuclea (rapitomidae)

Theta lyronuclea (Clarke, 1959)是北大西洋深水物种，首次在大西洋西南部被记录到。这构成了该属的第一次记录和第二次提及阿根廷的Raphitomidae科。这些样本于2013年9月在阿根廷大陆斜坡上的Mar del Plata海底峡谷的R/V Puerto Deseado上收集，深度为2,934米。提供了原海螺的核、阴茎和装饰细节的照片。将收集的标本与模式材料和北大西洋地区的几批标本进行详细比较，证实了这一鉴定。
