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.^[1]
