Entonomenia Leloup, 1948

Rhopalomeniidae with only one pair of foregut glandular organs, characterised by a duct with subepithelial/extraepithelial glandular cells (so­called type A); with separate mouth opening, without radula, with dorsoterminal sense organ, with unpaired secondary genital opening, without copulatory stylets or respiratory organs. Type species Entonomenia atlantica Leloup, 1948 (off Canary Islands, 540 m; holotype as section series in MOM). Six other species originally classified under Rhopalomenia are herewith transferred to the restored genus, five of which were originally described by Salvini­Plawen 1978 (E. carinata, E tricarinata , E. sertularicola , E. cristata , E. rhynchopharyngeata ) and E. microporata ( Handl & Salvini­Plawen 2002) .

Urgorria García­Álvarez & Salvini­Plawen, 2001 = Rhopalomeniidae with only one pair of foregut glandular organs, characterised by epithelial/intraepithelial glandular cells (so­called type C), and with a common atrio­buccal cavity; other characters as in Rhopalomenia above. Type species Urgorria compostelana García­Álvarez & Salvini­Plawen, 2001 . The genus also includes U. monoplicata Salvini­Plawen, 2003 .

Dinomenia Nierstrasz, 1902 = Rhopalomeniidae with one pair of foregut glandular organs with subepithelial/extraepithelial glandular cells draining through a distinct duct (type A), with a distichous radula and with copulatory stylets; terminal sense organ present. To date only the type species Dinomenia hubrechti Nierstrasz, 1902 , is known.

Driomenia Heath, 1911 = Rhopalomeniidae with one pair of foregut glandular organs with duct and subepithelial/extraepithelial glandular cells (type A), without terminal sense organ, pericardium with a pair of ventro­anterior diverticles; other characters as in Entonomenia above. Only the type species Driomenia pacifica Heath, 1911 , is known.

Pruvotia Thiele, 1894 = Rhopalomeniidae of somewhat uncertain status due to the presence of two (respiratory?) folds in the pallial cavity and a lack of information on foregut glandular organs; other characters as in Driomenia Heath. Only the type species is known, described as Proneomenia sopita Pruvot, 1891 .
