Choeradoplana is a genus of land planarians found in South America.
Species of the genus Choeradoplana are characterized by the presence of a cephalic retractor muscle associated with cephalic glands, forming a cephalic musculo-glandular organ in a way similar to the one found in the genera Luteostriata and Issoca . The head of Choeradoplana is highly rolled backwards and the ventral area thus visible has two "cushions" formed by the musculo-glandular organ. [1] This peculiar head shape makes it easy to identify a species as belonging to this genus.
The name Choeradoplana comes from Greek word χοιράς (scrofula) and the Latin word plana (flat) due to the two cushions on the ventral side of the head that resemble the neck swellings in patients affected by scrofula. [2]
The genus Choeradoplana currently includes the following 24 species: [3] [4]
Girardia is a genus of freshwater planarians belonging to the family Dugesiidae.
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.
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.
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.
Obama nungara is a species of land planarian in the family Geoplanidae. It is native to South America, but has been introduced in Europe.
Gigantea is a genus of land planarians from the Neotropical realm.
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.
Matuxia is a genus of land planarians from Brazil.
Geoplanini is a tribe of land planarians in the subfamily Geoplaninae.
Sarcoplanini is a tribe of land planarians in the subfamily Geoplaninae.
Choeradoplana agua is a species of land planarian belonging to the subfamily Geoplaninae. It is known from specimens found in Desengano State Park in Brazil.
