Matuxia Matuta
''Matuxia'' is a genus of land planarians from Brazil. Description The genus ''Matuxia'' is characterized by having a slender body with nearly parallel margins, reaching up to 12 cm in length, and being slightly convex on both dorsal and ventral sides. The eyes are arranged along the body margins, not occupying the dorsum. The copulatory apparatus has an apparent penis papilla, a structure similar to a true penis papilla, but having an ejaculatory cavity instead of an ejaculatory duct. The female cavity is rounded and filled with a multilayered epithelium. Etymology ''Matuxia'' is a portmanteau of the specific epithets of the two first species of the genus to be described, ''matuta'' and ''tuxaua'', and the first name of Eudóxia Maria Froehlich, who described both ''M. matuta'' and ''M. tuxaua''. Species There are three species assigned to the genus ''Matuxia'': *'' Matuxia matuta'' (E. M. Froehlich, 1955) *''Matuxia tuxaua ''Matuxia'' is a genus of land plana ...

Eudóxia Maria Froehlich
Eudóxia Maria Froehlich (21 October 1928 – 26 September 2015) was a Brazilian zoologist. Life Born in 1928, Eudóxia Maria de Oliveira Pinto was the daughter of Alice Alves de Camargo and the ornithologist Olivério Mário de Oliveira Pinto. Since she was a child, her parents used to take her and her siblings to the wooded areas near São Paulo, which helped her to become interested in zoology, especially small animals.Carbayo, F. (2013) "Vida de Zoólogo: Eudóxia Maria Froehlich." ''Informativo da Sociedade Brasileira de Zoologia'' 106: 7–10. After finishing High School, she spent six months in Rio de Janeiro with an uncle who was a physician and returned home interested in studying medicine. Her father did not approve the idea, considering it an inappropriate career for a woman, and suggested her to study natural history and so she did. During this time she became engaged to Claudio Gilberto Froehlich, one of her colleagues. In 1951 she and Froehlich started their doct ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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. phylogenetic analysis should c ...

Land Planarian
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 ...

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 i ...

Epithelium
Epithelium or epithelial tissue is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue. It is a thin, continuous, protective layer of compactly packed cells with a little intercellular matrix. Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. An example is the epidermis, the outermost layer of the skin. There are three principal shapes of epithelial cell: squamous (scaly), columnar, and cuboidal. These can be arranged in a singular layer of cells as simple epithelium, either squamous, columnar, or cuboidal, or in layers of two or more cells deep as stratified (layered), or ''compound'', either squamous, columnar or cuboidal. In some tissues, a layer of columnar cells may appear to be stratified due to the placement of the nuclei. This sort of tissue is called pseudostratified. All glands are made up of epi ...

Portmanteau
A portmanteau word, or portmanteau (, ) is a blend of wordsGarner's Modern American Usage , p. 644. in which parts of multiple words are combined into a new word, as in ''smog'', coined by blending ''smoke'' and ''fog'', or ''motel'', from ''motor'' and ''hotel''. In , a portmanteau is a single morph that is analyzed as representing two (or more) underlying s. When portmanteaus shorte ...
