Neppia Jeanneli
''Neppia'' is a genus of dugesiid triclad that is found in South America, Subantarctic region, Africa, Tasmania and New Zealand. Until 1974 ''Neppia'' was considered a subgenus of ''Dugesia''.Ball, I. R. 1974.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Schmidtea
''Schmidtea'' is a genus of freshwater triclads. Species of the genus ''Schmidtea'' are widely used in regeneration and developmental studies. Until 1991, ''Schmidtea'' was considered as a subgenus of ''Dugesia'', then it was elevated to the genus rank. Etymology The genus was presumably named after Eduard Oscar Schmidt Eduard Oscar Schmidt (21 February 1823, in Torgau – 17 January 1886, in Kappelrodeck) was a German zoologist and phycology, phycologist. Biography He initially studied mathematics and science at University of Halle, Halle, then continued his ..., who described two species within the genus.

Dugesiid
Dugesiidae is a family of freshwater planarians distributed worldwide (except Antarctica). The type genus In biological taxonomy, the type genus (''genus typica'') is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearin ... is '' Dugesia'' Girard, 1850. Description All species of Dugesiidae live in freshwater environments and have a dorsoventrally flattened body. The head usually has a somewhat triangular shape and has two eyes (except for some subterranean eyeless species). The main differences between Dugesiidae and other freshwater planarians are related to the anatomy of the eyes and the copulatory apparatus. The eye cup in Dugesiidae is composed of several retinal cells, while in other freshwater planarians they are composed of a single cell. All freshwater planarians have an accessory organ called copulatory bursa or ''bursa copulatrix'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cura (genus)
''Cura'' is a genus of freshwater flatworm (triclads) belonging to the family Dugesiidae. ''Cura'' was ranked as a subgenus of ''Dugesia'' until 1974, then it was elevated to the genus rank.

Girardia
''Girardia'' is a genus of freshwater Tricladida, planarians belonging to the family Dugesiidae. Distribution The genus ''Girardia'' is endemic to the Americas, from Argentina to Canada, although most species occur in South America. The only two species known to occur naturally in North America, ''Girardia tigrina'' and ''Girardia dorotocephala'', have been introduced in other continents and islands. Description Species of ''Girardia'' are very similar to species of other genera of Dugesiidae and few apomorphy, apomorphies that clearly define the genus are known. One of the few exclusive characteristics is the presence of pigment granules in the outer pharyngeal wall. Until 1991 ''Girardia'' was considered a subgenus of ''Dugesia'', then it was upgraded to the genus rank. However, some works continued to use the old genus for some ''Girardia'' species, mainly for ''Girardia dorotocephala'' and ''Girardia tigrina''.
