Recent molecular phylogenetic investigations strongly supported the placement of the shell-less, worm-shaped aplacophoran molluscs (Solenogastres and Caudofoveata) and chitons (Polyplacophora) in a clade called Aculifera, which is the sister taxon of

The family Pruvotinidae (Solenogastres, Cavibelonia) comprises 34 species grouped in 15 genera, five subfamilies and one uncertain subfamily. Three genera with 15 species make up the subfamily Pruvotininae characterized by hook-shaped, hollow acicular

During the Spanish oceanographic expedition for the study of Antarctic benthos, Bentart-2006, carried out in the area of the Bellingshausen Sea and Antarctic Peninsula, seven specimens of Proneomeniidae (Solenogastres, Cavibelonia) were obtained. Proneomenia

A new genus and two new species of Mollusca Solenogastres belonging to the family Simrothiellidae are described here: Spiomenia pusilla sp. nov. and Adoryherpia serrata gen. et sp. nov., collected from muddy sediment during the expedition DIVA 1 Me48/1

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
