Caenoplanini is a tribe of land planarians in the subfamily Rhynchodeminae mostly found throughout the Australasian and Oceanian realms. [1]
The tribe Caenoplanini is defined as containing land planarians with multiple eyes along the body, which do not spread dorsally, ventrally located testes and a thick layer of longitudinal muscles. [2]
Based on morphological evidence, species now classified as Caenoplanini were initially considered a subfamily, Caenoplaninae, and sister group of the subfamily Geoplaninae. Both were united by the presence of multiple eyes along the body and distinguished from each other by the presence of dorsal testes in Geoplaninae and ventral ones in Caenoplaninae. [2]
However, molecular studies revealed that this classification was artificial and that Caenoplaninae were actually closely related to Rhynchodeminae. Therefore, recent classification puts the former subfamilies Rhynchodeminae and Caenoplaninae as tribes, respectively Rhynchodemini and Caenoplanini, within an expanded subfamily Rhynchodeminae. This group is supported by molecular phylogeny, but there are no known synapomorphies. [3]
Currently the tribe Caenoplanini comprises the following genera:
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms.
Platydemus is a genus of large predatory land planarians in the tribe Rhynchodemini.
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.
Geoplanoidea is a superfamily of freshwater and land triclads that comprises the species of the Geoplanidae and the Dugesiidae families.
Microplaninae is a subfamily of land planarians.
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region.
Luteostriata is a genus of land planarians from Brazil characterized by a yellow body with dark longitudinal stripes.
Obama is a genus of land planarians from South America. It contains several species adapted to human-disturbed environments, including the only invasive land planarian native to the Neotropical realm, Obama nungara, which has been accidentally 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.
Geoplana is a genus of land planarians found in South America.
Polycladus is a genus of land planarians from South America.
Notogynaphallia is a genus of land planarians from South America.
Rhynchodeminae is a subfamily of land planarians with a worldwide distribution.
Rhynchodemini is a tribe of land planarians in the subfamily Rhynchodeminae.
Anzoplanini is a tribe of land planarians in the subfamily Rhynchodeminae.
Cotyloplana is a genus of land planarians in the tribe Rhynchodemini.
Digonopyla is a monotypic genus of land planarians in the tribe Rhynchodemini. It contains a single species, Digonopyla harmeri.
Pelmatoplanini is a tribe of land planarians in the subfamily Rhynchodeminae.
