Dolichoplana Carvalhoi
''Dolichoplana'' is a genus of land planarians in the tribe Rhynchodemini. Description Species of the genus ''Dolichoplana'' are characterized by a very elongate and flattened body with creeping sole of moderate width. The anterior end is rounded and slightly concave, bordered by glandular and sensory tracts, and has two large eyes. The parenchymal longitudinal musculature is restricted to the ventral region. The copulatory apparatus has a long and folded chamber in the male atrium, without a penis papilla. A prominent diverticulum opens into the common atrium from its posterior wall. Species The genus ''Dolichoplana'' currently contains three species: * '' Dolichoplana carvalhoi'' Corrêa, 1947 * '' Dolichoplana striata'' Moseley Moseley is a suburb of south Birmingham, England, south of the city centre. The area is a popular cosmopolitan residential location and leisure destination, with a number of bars and restaurants. The area also has a number of boutiques and ...

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 ...

Diva Diniz Corrêa
Diva Diniz Corrêa (10 May 1918 – 28 April 1993) was a Brazilian marine zoologist. Life Diva Diniz Corrêa was born in 1918 in Avaré, São Paulo, Brazil, being the younger of three sisters and the only one to attend college. In 1939, she began her studies in Natural History at the Faculdade de Filosofia, Ciências e Letras of the University of São Paulo. During this time, she worked closely with Ernst Marcus and Eveline Du Bois-Reymond Marcus, becoming good friends with them. After graduating in 1941, she apprenticed with Dr. Ottorino de Fiore di Coprani in the Department of Geology and Paleontology. From 1943 to 1945, she taught natural history in a country school near São Paulo, when she was then offered a professorship at the University of São Paulo and started to teach courses in Zoology and Physiology. At this time she made several trips to the coast to collect specimens for her classes and her research. In 1948, Diva completed her doctoral thesis on the embryo ...

Henry Nottidge Moseley
Henry Nottidge Moseley Fellow of the Royal Society, FRS (14 November 1844 – 10 November 1891) was a British natural history, naturalist who sailed on the global scientific expedition of Challenger expedition, HMS ''Challenger'' in 1872 through 1876. Life Moseley was born in Wandsworth, London, the son of Henry Moseley (mathematician), Henry Moseley. He was educated at Harrow School, at Exeter College, Oxford (Arts) and at the University of London (medicine). He married Amabel Gwyn Jeffreys, daughter of the conchologist John Gwyn Jeffreys, in 1881, and they were the parents of the noted British people, British physicist Henry Moseley, Henry Gwyn Jeffreys Moseley. Moseley delivered the Royal Society Croonian Lecture in 1878 and was elected as a Fellow of the Royal Society in 1879. He participated as naturalist in expeditions to Ceylon, to California, and to Oregon, and most notably he was in the Challenger expedition, ''Challenger'' expedition aboard of 1872 through 1876 which ...

Eveline Du Bois-Reymond Marcus
Eveline du Bois-Reymond Marcus (6 October 1901 – 31 January 1990) was a German zoologist and drawer. Life Eveline Du Bois-Reymond was the youngest daughter of Rene and Frieda du Bois-Reymond, as well as a granddaughter of physiologist Emil Du Bois-Reymond. Her father was also a professor of physiology at Berlin University. Her interest in zoology started when she was still a young girl and used to watch small animals in her father's microscope.Corrêa, D.D. (1991) Dr Eveline du Bois-Reymond Marcus. ''Hydrobiologia'', 227: xxiii-xxvi. From 1923 to 1924, she attended zoology courses at the Berlin University, but did not conclude them because she met a professor of zoology, Ernst Marcus and married him. Together, they started a strong collaboration in zoology, including the study of several invertebrate groups, such as protozoans, ctenophores, flatworms, nemertines, annelids, tardigrades, onychophorans, bryozoans, gastropods, and pycnogonids.
