Matuxia is a genus of land planarians from Brazil.
The genus Matuxia is characterized by having a slender body with nearly parallel margins, reaching up to 12 cm in length, and being slightly convex on both dorsal and ventral sides. The eyes are arranged along the body margins, not occupying the dorsum. The copulatory apparatus has an apparent penis papilla, a structure similar to a true penis papilla, but having an ejaculatory cavity instead of an ejaculatory duct. The female cavity is rounded and filled with a multilayered epithelium. [1]
Matuxia is a portmanteau of the specific epithets of the two first species of the genus to be described, matuta and tuxaua, and the first name of Eudóxia Maria Froehlich, who described both M. matuta and M. tuxaua. [1]
There are three species assigned to the genus Matuxia:
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.
Supramontana is a genus of land planarians from South America.
Cephaloflexa is a genus of land planarians from Brazil.
Paraba is a genus of land planarians from South America.
Imbira is a genus of land planarians found in South America.
Cratera is a genus of land planarians found in South America.
Geoplana is a genus of land planarians found in South America.
Pasipha is a genus of land planarians from South America.
Notogynaphallia is a genus of land planarians from South America.
Issoca is a genus of land planarians from Brazil.
Endeavouria is a monotypic genus of land planarians from the Pacific region. It contains a single species, Endeavouria septemlineata.
Eudóxia Maria Froehlich was a Brazilian zoologist.
Amaga is a genus of land planarians from South America.
Luteostriata abundans is a species of Brazilian land planarian in the subfamily Geoplaninae. It is a common species in human-disturbed areas in Brazil's southernmost state, Rio Grande do Sul.
Imbira guaiana is a species of land planarian in the subfamily Geoplaninae. It is the type species of the genus Imbira and is found in Brazil.
Luteostriata ceciliae is a species of Brazilian land planarian in the subfamily Geoplaninae.
Choeradoplana iheringi is a species of land planarian in the subfamily Geoplaninae found in Brazil.
