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

Description

Species of Humbertium are characterized by the presence of a well developed penis papilla in the copulatory apparatus, similar to the one in Bipalium , but with the ovovitelloducts entering the female atrium anteriorly and not posteriorly as in Bipalium. ^[1]

Etymology

The genus Humbertium is named after the Swiss naturalist Aloïs Humbert who described several species from Sri Lanka that are now classified in the genus. ^[1]
