Imbira
''Imbira'' is a genus of land planarians found in South America. Description The genus ''Imibira'' is characterized by having a large, slender and flat body with parallel margins, reaching up to 14 cm in length. The eyes are arranged along the body margins, not occupying the dorsum. In comparison to other genera, the body has an additional layer of longitudinal muscles dorsally and ventrally to the intestine. The copulatory apparatus lacks a permanent penis, i. e., the penis is formed during copulation by folds in the male cavity. The female cavity is rounded and filled with a multilayered epithelium. Etymology ''Imbira'' is a word in the Tupi language that refers to a strip of bark peeled off from certain trees. Species There are four species assigned to the genus ''Imbira'': *''Imbira flanovigra'' Amaral & Leal-Zanchet, 2018 *''Imbira guaiana'' (Leal-Zanchet & Carbayo, 2001) *''Imbira marcusi'' Carbayo et al., 2013 *''Imbira negrita ''Imbira'' is a genus of lan ...

Imbira Guaiana
''Imbira guaiana'' is a species of land planarian in the subfamily Geoplaninae. It is the type species of the genus ''Imbira'' and is found in Brazil. Description ''Imbira guaiana'' is a medium-sized land planarian with an elongate body reaching up to in length and in width while crawling. Its dorsal surface has a greyish-olive color and the ventral side is yellowish-olive. The numerous small eyes are arranged long the body margins from the anterior to the posterior tip. Etymology The specific epithet ''guaiana'' refers to the Kaingang people The Kaingang (also spelled ''caingangue'' in Portuguese or ''kanhgág'' in the Kaingang language) people are an Indigenous Brazilian ethnic group spread out over the three southern Brazilian states of Paraná, Santa Catarina and Rio Grande ... (also known as ''guainás'' or ''guaianos'') that in the past inhabited the region where the species is found. Distribution The only known place of occurrence of ''I. guaiana'' is th ...

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 ...

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 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 ...

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 epithe ...

Tupi Language
Old Tupi, Ancient Tupi or Classical Tupi (also spelled as Tupí) is an extinct Tupian language which was spoken by the aboriginal Tupi people of Brazil, mostly those who inhabited coastal regions in South and Southeast Brazil. It belongs to the Tupi–Guarani language family, and has a written history spanning the 16th, 17th, and early 18th centuries. In the early colonial period, Tupi was used as a ''lingua franca'' throughout Brazil by Europeans and aboriginal Americans, and had literary usage, but it was later suppressed almost to extinction. Today, only one modern descendant is living, the Nheengatu language. The names Old Tupi or classical Tupi are used for the language in English and by modern scholars (it is referred to as in Portuguese), but native speakers called it variously "the good language", "common language", "human language", in Old Tupi, or, in Portuguese, "general language", "Amazonian general language", "Brazilian language".
