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.^[1]

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.^[2]
