This genus was erected for teeth that had previously been included in Ginglymostoma, but which showed a number of morphological differences from other teeth ascribed to this genus. Noubhani & Cappetta (1997) deemed relevant:
1) Laterally compressed and labio-lingually elongated teeth in all file positions (relative to other members of the genus).
2) Low number of lateral cusplets (not exceeding two pairs)
3) A strong medio-vertical crest on the labial face of the cusp.

A single species is attributed to this genus - Delpitoscyllium africanum (LERICHE 1927). Teeth of this species have been reported from the Palaeocene (Danian & Thanetian) of western Africa (Morocco, Cabinda, Zaire) and the Palaeocene (Selandian) and Eocene (Ypresian) of eastern North America (Maryland and Virginia).

In defining the genus, the authors noted that the teeth are longer than broad with a triangular cusp and a pair (2nd pair in lateral positions) of divergent lateral cusplets. The cusplets develop low on the crown face but project relatively high. The apron is long and broadly rounded in anterior files and slightly bifid in lateral files. The strongly projecting medio-lingual protuberance of the crown does not fully cover the root. The root is rather high, labio-lingually elongated with a heart-shaped outline and weakly convex basal face. The central foramen is broad & elliptical and located lingually in the nutrient groove. Small margino-lingual foramina are also present.
