Material studied. None.

Remarks. The generic identity of N. sendenhorstensis is uncertain. Tshudy (1993, pp. 285, 370‒371) concluded that the cephalothorax, pleon (with broken pleura) and heavy, isochelous claws were unlike those of Oncopareia , and treated the specimen as “ Nymphaeops” sendenhorstensis .

Range and occurrence. Upper Cretaceous, upper ‘Senonian’ (probably late Campanian) of Sendenhorst, near Münster, western Germany ( Mertin, 1941, p. 180) and lower Maastrichtian of the Liège-Limburg Basin, northeast Belgium and the southeast Netherlands ( Pelseneer, 1886, p. 173).
