Novibipalium is a genus of land planarians of the subfamily Bipaliinae (hammerhead flatworms).

Description

Species of Novibipalium are very similar to those of the related genus Bipalium . The main difference occurs in the copulatory apparatus, which in Novibipalium lacks a well-developed penis papilla, while in Bipalium a penis papilla is present. Novibipalium has a set of folds in the copulatory apparatus that are everted during mating and create a temporary penis. ^[1]

• Novibipalium alterifuscatum Kawakatsu, Ogren & Froehlich, 1998
• Novibipalium falsifuscatum Kawakatsu, Ogren & Froehlich, 1998
