'''''Traklosia''''' is a genus of nematodes. The genus was originally circumscribed in 1961 under the deprecated name ''Robertia''. 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.<ref name="Bernard et al., 2015" /> Travassos and Kloss had circumscribed the genus ''Robertia'' for their newly-described species ''Robertia leiperi'' in 1961.<ref name="Travassos et al., 1961" /> The generic name ''Robertia'' was unavailable because a senior homonym, the synapsid genus ''Robertia'', was named in 1948.<ref name="Bernard et al., 2015" />
''Traklosia'' is the type genus of the family Traklosiidae, which was changed from Robertiidae.<ref name="Bernard et al., 2015" /> The genus ''Triumphalisnema'' is in the same family.<ref name="Bernard et al., 2015" /> Travassos and Kloss initially placed their genus ''Robertia'' in a new subfamily Robertiinae in the family Thelastomatidae.<ref name="Travassos et al., 1961" /> George Poinar Jr. recognized Robertiidae as its own family in 1977.<ref name="Phillips et al., 2016" /> In 1989, Adamson synonymized Robertiidae with Thelastomatidae.<ref name="Adamson et al., 1992" /> The family Traklosiidae is thought to be valid according to Gary Phillips and colleagues.<ref name="Phillips et al., 2016" />
===Species=== {{As of|2015}}, 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''.<ref name="Bernard et al., 2015" /> ''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.<ref name="Travassos et al., 1961"/> ''T. longicauda'' was described in 1995 by Nayla García, Alberto Coy, and Marianela Álvarez, all parasitologists at the Cuban Academy of Sciences.<ref name="Garcia et al., 1995" />
==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).<ref name="Adamson et al., 1992"/> Males have a caudal extremity which suddenly narrows half-way making its end thread-like. Their genital cone is well developed.<ref name="Adamson et al., 1992"/>
==Distribution== ''Traklosia'' is found in South America and the West Indies.<ref name="Adamson et al., 1992" /> ''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.<ref name="Garcia et al., 2002"/> ''T. leiperi'' has been recorded in the Brazilian state of Rio de Janeiro.<ref name="Adamson et al., 1992" /><ref name="Travassos et al., 1961" />
==Hosts== ''Traklosia'' species infect hosts in the orders Coleoptera and Diplopoda.<ref name="Jex et al., 2006" /> ''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''.<ref name="Garcia et al., 2002"/> ''T. leiperi'' has been found in the millipede species ''Eurydesmus ruidus''.<ref name="Travassos et al., 1961" /> <!---The table in Jex et al. 2006 says it also it has hosts in the order Coleoptera based on an examination of the literature -- I haven't seen this elsewhere though. Other sources I've found only mention Diplopoda hosts.--->
