Pasipha

Pasipha is a genus of land planarians from South America.

Description
Species of the genus Pasipha have a slender and flattened body with parallel margins while creeping. The copulatory apparatus lacks a permanent penis, having a long and highly folded male atrium instead. The prostatic vesicle is located outside the muscular coat of the copulatory apparatus and divided in two portions. The female canal enters the genital antrum ventrally.

Etymology
The name of Pasipha is derived from the specific epithet of the type species, Pasipha pasipha, known as Geoplana pasipha prior to the creation of the genus.
