Othelosoma is a genus of land planarians found in Africa and India. [1]
The genus Othelosoma is characterized by having an elongate, rounded body, generally only two eyes and a blunt anterior end. The copulatory apparatus has a permanent penis. The bursa copulatrix is large and communicates with the genital atrium by two canals, the vaginal duct and the Beauchamp's canal. [2]
There are 40 species assigned to the genus Othelosoma: [1]
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms.
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 as invasive to the United States and to 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.
Microplana is a genus of land planarians found in Europe and Africa.
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.
