Traklosia
Traklosia is a genus of nematodes. The genus was originally circumscribed in 1961 under the name "Robertia"; L. Travassos and G. R. Kloss created this genus for their newly-described species "R. leiperi". The nomen novum, "Traklosia", was created for this genus in 2015 — "Robertia" was an invalid name due to a senior homonym. It consists of three species found in Brazil and Cuba, and they are parasites of millipedes. Taxonomic history. In 2015, Ernest C. Bernard and Gary Phillips coined "Traklosia" as nomen novum for "Robertia". The word "Traklosia" comes from the first three letters in the surnames  of L. Travassos and G. R. Kloss. Travassos and Kloss had circumscribed the genus "Robertia" for their newly-described species "Robertia leiperi" in 1961. The generic name "Robertia" was unavailable because a senior homonym, the synapsid genus "Robertia", was named in 1948. "Traklosia" is the type genus of the family Traklosiidae, which was changed from Robertiidae. The genus "Triumphalisnema" is in the same family. Travassos and Kloss initially placed their genus "Robertia" in a new subfamily Robertiinae in the family Thelastomatidae. George Poinar Jr. recognized Robertiidae as its own family in 1977. In 1989, Adamson synonymized Robertiidae with Thelastomatidae. The  family Traklosiidae is thought to be valid according to Gary Phillips and colleagues. Species. , three species are recognized in the genus "Traklosia". All of them were initially described with the generic name "Robertia". The three species are: "T. cubana", "T. leiperi", and "T. longicauda". The type species is "T. leiperi", under its original combination "Robertia leiperi". "T. cubana" was described in 1984 by S. E. Spiridonov of the USSR Academy of Science. "T. leiperi" was described in 1961 by L. Travassos and G. R. Kloss of the Oswaldo Cruz Institute. "T. longicauda" was described in 1995 by Nayla García, Alberto  Coy, and Marianela Álvarez, all parasitologists at the Cuban Academy of Sciences. Diagnosis and description. Females in this genus are very small. The female reproductive system has only one genital tract. Their uteri are parallel and oriented to their posterior. They bear a single egg at a time, and eggs are ovalish. Their vagina points anteriorly and is in the posterior third of their body (excluding the tail). Males have a caudal extremity which suddenly narrows half-way making its end thread-like. Their genital cone is well developed. Distribution. "Traklosia" is found in South America and the West Indies . "T. cubana" and "T. longicauda" are both found in Cuba: "T. cubana" has been recorded in Guantánamo along the "Carretera Central" between Imías and Baracoa, and "T. longicauda" has been recorded in the National Botanical Garden in Havana. "T. leiperi" has been recorded in the Brazilian state of Rio de Janeiro. Hosts. "Traklosia" species infect hosts in the orders Coleoptera and Diplopoda. "T. cubana" and "T. longicauda" have both been found in the millipede genus "Rhinocricus": "T. cubana" has been found in an unspecified "Rhinocricus" species and "T. longicauda" has been found in "R. duvernoyi". "T. leiperi" has been found  in the millipede species "Eurydesmus ruidus".
