Rhynchodemus is a genus of land planarians in the tribe Rhynchodemini.
Species of the genus Rhynchodemus are characterized by an elongate body that is attenuated at both ends, oval or round in cross section. The creeping sole occupies most of the ventral surface and the anterior end has two large eyes. The copulatory apparatus has a large chamber with folded epithelium in the male atrium, without a penis papilla. [1]
The genus Rhynchodemus includes the following species:
Convolutidae is a family of acoels. It contains more than a third of all known acoel species.
Paul David Gustav du Bois-Reymond was a German mathematician who was born in Berlin and died in Freiburg. He was the brother of Emil du Bois-Reymond.
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. Native to Asia, several species are 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.
Oroperipatus is a genus of Neotropical velvet worms in the family Peripatidae. Species in this genus are found in South America west of the Andes and in Mexico. Velvet worms in this genus can have as few as 22 pairs of legs or as many as 40 leg pairs. This genus is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Microplana is a genus of land planarians found in Europe and Africa.
Acanthozoon is a genus of polyclad flatworms belonging to the family Pseudocerotidae.
Piseinotecus is a genus of sea slugs, aeolid nudibranchs, marine gastropod mollusks in the family Piseinotecidae.
Geoplana is a genus of land planarians from South America.
Pasipha is a genus of land planarians from South America.
Eveline du Bois-Reymond Marcus was a German zoologist and drawer.
Notogynaphallia is a genus of land planarians from South America.
Amaga is a genus of land planarians from South America.
Gigantea is a genus of land planarians from the Neotropical realm.
Othelosoma is a genus of land planarians found in Africa and India.
Kontikia is a genus of land planarians native from islands in the Indo-Pacific region, but several species have been introduced elsewhere.
Dolichoplana is a genus of land planarians in the tribe Rhynchodemini.
Humbertium is a genus of land planarians of the subfamily Bipaliinae.
Incapora is a genus of land planarians in the subfamily Microplaninae.
Pseudogeoplana is a genus of land planarians of the subfamily Geoplaninae. It was erected to include species lacking sufficient morphological information to allow them to be classified in the appropriate genus.
