Moravecnema is a genus of parasitic nematodes, belonging to the family Cystidicolidae. Species of Moravecnema are parasitic as adults in the gastrointestinal tract of fish. [1][2] According to the World Register of Marine Species, the genus currently (2019) includes a single species, Moravecnema segonzaci,[2] which is a parasite in a deep-sea fish.

Description
editThe genus Moravecnema is characterised by a dorsoventrally elongated oral opening, rudimentary pseudolabia, and four pairs of precloacal and six pairs of postcloacal caudal papillae in the male.[1]
Etymology
editThe name of the genus Moravecnema was created in the honour of Czech parasitologist František Moravec, "in recognition to his outstanding work on systematics of fish nematodes".[1] The gender is neuter. The specific epithet segonzaci refers to Michel Segonzac, from Ifremer, France, who collected the specimens.[1]
Hosts and localities
edit
Moravecnema segonzaci Justine, Cassone & Petter, 2002 is a parasite of the intestine of the eelpout Pachycara thermophilum (Zoarcidae) from the hydrothermal sites Logatchev and Snake Pit-Moose of the Mid-Atlantic Ridge, at depths of 3,000-3,510 m.[1] The fish were caught by slurp gun by the submarine DSV Alvin. The fish is a deep sea fish and this nematode is one of the few species recorded from deep-sea fish.[3]
