Triplignathia adriatica, a new genus and species of Gnathostomulida in the family Austrognathiidae, is described from two localities in the Adriatic (Mediterranean). Owing to the possession of three rows of jaw teeth the new genus occupies one end of a morphological cline along which the species of Austrognathiidae can be arranged; the other end is occupied by species of Austrognatharia with two rows of teeth one of which has only one tooth. Species of the third genus in the family, Austrognathia, with two full rows of teeth, lie between these extremes.
