  • 摘要:Cancellariidae is a poorly known family of Neogastropods, including about 300 soft-bottom dwelling species, with a cosmopolitan distribution. As cancellariids are seldom found alive, anatomical data on this family are limited. In particular, no anatomical descriptions have been available thus far for the trigonostomatine group, a conchologically well-defined monophyletic lineage of Cancellariidae that was given a subfamilial rank in former classifications. This is the first description of the anatomy of two closely related and conchologically very similar trigonostomatine Cancellariidae: Scalptia androyensis and S. foveolata. Evident differences were detected in these two species, including the shape and arrangement of the salivary glands, the relative size of the mid and posterior oesophagous, and the structure of the pallial oviduct. Such an unexpected degree of anatomical differentiation, if more widespread in cancellariids, may prove useful in species identification of conchologically similar taxa. Instead, different shell colour morphs of S. androyensis did not display anatomical differences, corroborating the hypothesis that they are conspecific.
