Gibsonnema nom. n., a new name for the nematode genus Paraseuratoides moravec, Salgado-Maldonado et Aguilar-Aguilar, 2002.

We have found that the generic name Paraseuratoides Moravec, Salgado-Maldonado et Aguilar-Aguilar, 2002 is a junior homonym to Paraseuratoides Wang, 1984. Therefore, a new name, Gibsonnema nom. n., is proposed to replace it (the new genus is named in honour of David I. Gibson, a wellknown English helminthologist). These two genera are monotypic, belonging to the seuratoid family Quimperiidae Gendre, 1928, and both their type species are parasitic in swamp-eels (Synbranchidae, Synbranchiformes). However, they are well separated morphologically. In contrast to Gibsonnema, the genus Paraseuratoides is characterised mainly by a toothless buccal cavity, a bulbously inflated anterior end of the oesophagus and the presence of caudal alae in the male.
