Anisorhynchodemus is a genus of land planarians of the tribe Rhynchodemini. It was erected to include species lacking sufficient morphological information to allow them to be classified in the appropriate genus. [1]
Many species of land planarians described during the second half of the 19th century and the first half of the 20th century were classified based solely on external characters. Currently, land planarian genera are highly based on internal anatomy, especially the anatomy of the copulatory apparatus. Consequently, species with old descriptions that were never redescribed, so that their internal anatomy remains unknown, cannot be assigned to the correct genus. Thus, the genus Anisorhynchodemus was erected to temporarily accommodate species of the tribe Rhynchodemini whose anatomy of the copulatory apparatus is still unknown. [1]
The name of Anisorhynchodemus is derived from the genus Rhynchodemus and the Greek άνισος (ánisos), meaning "unusual, different, irregular, dissimilar". [2]
The genus Anisorhynchodemus currently contains the following species:
Bipalium is a genus of large predatory land planarians. They are often loosely called "hammerhead worms" or "broadhead planarians" because of the distinctive shape of their head region. Land planarians are unique in that they possess a "creeping sole", a highly ciliated region on the ventral epidermis that helps them to creep over the substrate. Several species are considered invasive to the United States, Canada, and Europe. Some studies have begun the investigation of the evolutionary ecology of these invasive planarians.
Platydemus is a genus of large predatory land planarians in the tribe Rhynchodemini.
Microplaninae is a subfamily of land planarians.
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.
