Pasipha

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.{{Cite journal | doi = 10.1111/zsc.12019| title = Molecular phylogeny of Geoplaninae (Platyhelminthes) challenges current classification: Proposal of taxonomic actions| journal = Zoologica Scripta| volume = 42| issue = 5| pages = 508| year = 2013| last1 = Carbayo | first1 = F. | last2 = Álvarez-Presas | first2 = M. | last3 = Olivares | first3 = C.

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.{{Cite web |last=Kawakatsu |first=Masaharu |author-link=Masaharu Kawakatsu |date=2009 |title=A List of Nominal Taxa of Planarians and Nemertean Described by Kawakatsu and His Coauthors |url=http://www.riverwin.jp/pl/nominal/Nominal%20Taxa%202009.pdf |website=Kawakatsu’s Web Library on Planarians |page=32 |format=PDF}}
