Cotyloplana Borneensis
''Cotyloplana'' is a genus of land planarians in the tribe Rhynchodemini. Description The genus ''Cotyloplana'' is characterized by a flat body with a wide creeping sole. There is one sucker located ventrally at the anterior end, in front of the creeping sole. The copulatory apparatus has a large spacious male atrium, with a small and obtuse penis papilla. A diverticulum opens into the common atrium from its posterior wall. Species The genus ''Cotyloplana'' currently contains two species: * '' Cotyloplana borneensis'' de Beauchamp, 1933 * '' Cotyloplana pilcata'' Whitehouse, 1914 * ''Cotyloplana punctata ''Cotyloplana'' is a genus of land planarians in the tribe Rhynchodemini Rhynchodemini is a tribe of land planarians in the subfamily Rhynchodeminae.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Land Planarians
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. They lack water-retaining mechanisms and are therefore very sensitive to humidity variations of their environment. Because of their strict ecological requirements, some species have been proposed as indicators of the conservation state of their habitats. They are generally animals with low vagility (dispersal ability) and with very specific habitat requirements, so they can be also used to accurately determine the distribution of biogeographic realms. Today the fauna of these animals is being studied to select conservation priorities in the Atlantic rainforest in Brazil. At the other extreme, one species in this family, ''Platydemus manokwari'' has become an invasive species in both disturbed and wild habitats in the ...

Rhynchodemini
Rhynchodemini is a tribe of land planarians in the subfamily Rhynchodeminae. Description The tribe Rhynchodemini is defined as containing land planarians with an elongate, cylindroid form, two eyes near the anterior end and strong subepithelial musculature in which the longitudinal fibers are grouped into large bundles. The copulatory apparatus lacks a penis papilla or has it greatly reduced. Genera The tribe Rhynchodemini contains six genera: *'' Anisorhynchodemus'' Kawakatsu, Froehlich, Jones, Ogren & Sasaki, 2003 *'' Cotyloplana'' Spencer, 1892 *'' Digonopyla'' Fischer, 1926 *'' Dolichoplana'' Moseley, 1877 *''Platydemus'' von Graff, 1896 *''Rhynchodemus ''Rhynchodemus'' is a genus of land planarians Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms.

Reproductive System Of Planarians
The reproductive system of planarians is broadly similar among different families, although the associated structures can vary in complexity. All planarians are hermaphrodites, so their reproductive system has a male and a female part. Both parts communicate with the surface of the body via a single opening called gonopore, which is located on the ventral side of the posterior half of the body. Male part of the reproductive system The male part of the reproductive system in planarians has a set of several testicles, distributed throughout the body in two or more rows. They are usually concentrated in the anterior two thirds of the body, although they can reach close to the posterior end. The testicles are connected to a pair of sperm ducts which run posteriorly towards the gonopore. In some groups, the sperm ducts met in their distal part, forming the ejaculatory duct, which then opens in a cavity called “male atrium”. In others, like land planarians, both open in the ...
