Microplaninae is a subfamily of land planarians. [1]
The subfamily Microplaninae was defined by Ogren and Kawakatsu (1988) [2] 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. [2] However, recent phylogenetic analyses indicated that both subfamilies are not closely related. [3]
Eight genera of Microplaninae are known: [1]

Dugesia is a genus of dugesiid triclads that contains some common representatives of the class Turbellaria. These common flatworms are found in freshwater habitats of Africa, Eurasia, and Australia. Dugesia is best known to non-specialists because of its regeneration capacities.
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms.
Continenticola is a clade that includes the land planarians (Geoplanidae) and the freshwater triclads.
Dugesiidae is a family of freshwater planarians distributed worldwide. The type genus is Dugesia Girard, 1850.
Girardia is a genus of freshwater planarians belonging to the family Dugesiidae.
Schmidtea is a genus of freshwater triclads. Species of the genus Schmidtea are widely used in regeneration and developmental studies.
Geoplanoidea is a superfamily of freshwater and land triclads that comprises the species of the Geoplanidae and the Dugesiidae families.
Cura is a genus of freshwater flatworm (triclads) belonging to the family Dugesiidae.
Bdellouridae is a family of Maricola triclads.
Microplana is a genus of land planarians found in Europe and Africa.
Neppia is a genus of dugesiid triclad that is found in South America, Subantarctic region, Africa, Tasmania and New Zealand.
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. Members of this family are sometimes referred to as the Neotropical land planarians. However, one species, Obama nungara has been introduced in Europe.
The reproductive system of planarians is broadly similar among different families, although the associated structures can vary in complexity.
Bipaliinae is a subfamily of land planarians found mainly in Madagascar, the Indian subcontinent and Southeast Asia, although some species have been introduced worldwide.
Rhynchodeminae is a subfamily of land planarians with a worldwide distribution.
Rhynchodemini is a tribe of land planarians in the subfamily Rhynchodeminae.
Caenoplanini is a tribe of land planarians in the subfamily Rhynchodeminae mostly found throughout the Australasian and Oceanian realms.
Gigantea is a genus of land planarians from the Neotropical realm.
Pelmatoplaninini is a tribe of land planarians in the subfamily Rhynchodeminae.
Novibipalium is a genus of land planarians of the subfamily Bipaliinae.
