Resumen

A taxonomic study based on fresh specimens from Argentina and Colombia, and voucher material from the collections of the Museo Argentino de Ciencias Naturales "Bernardino Rivadavia" (MACN) and Museo de Historia Natural Marina de Colombia (MHNMC-INVEMAR) was conducted. The first study by scanning electron microscopy (SEM) of the radular, jaw elements and reproductive anatomy, paying special attention to the internal cuticular stylet of the penis, is presented. Previous descriptions of P. incoiispicua and its junior synonyms, P. hamva. P. Iiedgpelhi, and P. gela,are compared with the present results; P. boiuiieae is synonymized and a checklist of the distinguishing features of relevant species within the genus Pleurohraiichaea is provided. This work aims at discussing the proposed amphiatlantic distribution of P. incoiispicua and at solving the problems of synonymies. It provides a starting point for a comparative study of specimens of the genus Pleurobninchaea from both sides of the Atlantic Ocean and the Mediterranean Sea that will be complemented with molecular studies in future times.
