Description
The subfamily Microplaninae was defined by Ogren and Kawakatsu (1988)Ogren, R. E. and Kawakatsu, M. (1988). Index to the species of the family Rhynchodemidae (Turbellaria, Tricladida, Terricola) Part I: Rhynchodeminae. Bulletin of Fujis Women's College. 26: 39-91. for land planarians with a short and cylindroid form, an anterior end that is 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. However, recent phylogenetic analyses indicated that both subfamilies are not closely related.{{Cite journal | last1 = Álvarez-Presas | first1 = M. | last2 = Baguñà | first2 = J. | last3 = Riutort | first3 = M. | doi = 10.1016/j.ympev.2008.01.032 | title = Molecular phylogeny of land and freshwater planarians (Tricladida, Platyhelminthes): From freshwater to land and back | journal = Molecular Phylogenetics and Evolution | volume = 47 | issue = 2 | pages = 555–568 | year = 2008 | pmid = 18359250}}
