Abstract

A further paper dealing with West Atlantic Gnathostomulida presents the new monotypic genus Tenuignathia. The presence of a full sensorium and a cuticular bursa place the new genus within the order Bursovaginoidea, sub‐order Scleroperalia; the simple jaws and pharynx, the bipartite ciliary pits as well as epithelial characters clearly suggest inclusion in the family Mesognathariidae. Found in Florida, North Carolina and Bermuda so far, Tenuignathia displays an unusually wide range of jaw length even within a narrow geographic range, which will be the subject of a separate study.
