Paraparaba is a genus of land planarians from South America.
Species of the genus Paraparaba have a slender body with nearly parallel margins while creeping. The largest specimens may reach about 8 cm in length. Both sides of the body are slightly convex. The pharynx is cylindrical and the prostatic vesicle is extrabulbar. The copulatory apparatus has a permanent, protrusible, conical penis occupying the entire male cavity, which is unfolded, and the female cavity is rounded and filled with a multilayered epithelium. [1]
Species in the genus Paraparaba were first assigned to a genus named Paraba, of which the chosen type species was Geoplana multicolorGraff, 1899. However, this was based on specimens that are not conspecific with the holotype of Geoplana multicolor. An analysis of the holotype indicated that it matches the definition of the genus Geoplana and not Paraba. This made Paraba become a junior synonym of Geoplana and the new name Paraparaba was chosen to include species previously in Paraba. [2]
Paraparaba means multicolored, with many colors in the Tupi language. It is formed by a reduplication of the word Paraba meaning variegated, and alludes to the name of the species Geoplana multicolor, which was originally chosen as the type species of Paraba. The name could also be interpreted as coming from Greek para, beside, plus the name of the former genus Paraba. [2]
The following species are recognised in the genus Paparaba:
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.
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.
Choeradoplana is a genus of land planarians found in 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 from South America.
Pasipha is a genus of land planarians from South America.
Notogynaphallia is a genus of land planarians from South America.
Barreirana is a genus of land planarians from Brazil, formerly considered a subgenus of Geoplana.
Eudóxia Maria Froehlich was a Brazilian zoologist.
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.
Paraba franciscana is a species of land planarian found in Brazil.
Luteostriata graffi is a species of Brazilian land planarian in the subfamily Geoplaninae.
Matuxia is a genus of land planarians from Brazil.
Paraparaba impositrix is a species of land planarian belonging to the subfamily Geoplaninae. It is found in areas of Atlantic Forest of Brazil and Argentina.
Geoplanini is a tribe of land planarians in the subfamily Geoplaninae.
