Microplaninae is a subfamily of land planarians.[1]

Description

The subfamily Microplaninae was defined by Ogren and Kawakatsu (1988)[2] for land planarians with a short and cylindroid form, anterior end blunt, eyes often small and subepithelial musculature weak. The male copulatory apparatus is often complicated and has a well-developed penis. The female apparatus is very variable, with or without a seminal bursa and with or without a connection with the intestine.

It was originally considered, based on morphological evidence, to be the sister group of the subfamily Rhynchodeminae.[2] However, recent phylogenetic analyses indicated that both subfamilies are not closely related.[3]

Genera

Eight genera of Microplaninae are known:[1]
