Abstract
Solenogastres are a small class of vermiform Mollusca that present a mantle with calcareous sclerites and a ventral pedal groove. During the expedition Me48/1 DIVA 1, carried out in the abyssal Angola Basin between 5100-5500 m depth, several specimens of Solenogastres were collected. Their study has made possible to describe two new species and a new genus of the family Acanthomeniidae Salvini-Plawen, 1978, whose anatomical features have caused the modification of the family definition.
