Abstract

Two new species of polyclads are described from the continental slope of the Gulf of Mexico. Specimens of Didangia carneyi sp. nov. and Oligocladus bathymodiensis sp. nov. were collected from the Louisiana slope at 610 m and 650 m, respectively. Didangia carneyi sp. nov. was collected from a natural wood fall, and is characterized by the presence of tentacular and cerebral eyes, an interpolated prostatic vesicle provided with two muscular accessory prostatic vesicles, and large glandular cells that surround the male atrium. Oligocladus bathymodiensis sp. nov. has a mouth anterior to the brain, a few cerebral and pseudotentacular eyes, four pairs of intestinal branches, and a ventral anal pore. Specimens of this species were collected on the margin of a hypersaline cold seep in association with mussels of Bathymodiolus childressi. All type material is deposited at the Field Museum of Natural History, Chicago, Illinois, USA.
