Diagnoza

Perhaps the poorly preserved, strongly compressed specimen ZPN, AwVW764  belongs here. The species has already been reported by Weyer (1965), who attributed another specimen from an old museum collection to the related N. heterolobatum (Vohringer, 1960), which seems to have, however, a more subacute venter.
