Humbertium Ogren & Sluys, 2001

Humbertium is a genus of land planarian. Like the rest of Bipaliinae members, their species present a semilunar head and a narrow creeping sole. They also have a continuous sensory groove, a collared pharynx, and a penis papilla. What makes this genus different from the rest of Bipaliinae is the anterodorsal entrance of the ovovitelline ducts into the female organs.

Type species - Humbertium ravenalae (von Graff, 1899).
