| Summary: | Oxydromus Grube, 1855 Oxydromus Grube, 1855: 98; Villalobos-Guerrero & Harris, 2012: 23. Ophiodromus Sars, 1862: 87; Pleijel, 1998: 137 –143. Type species: Oxydromus fasciatus Grube, 1855, by monotypy. Diagnosis (modified from Pleijel 1998; Parapar et al. 2004): Ophiodrominae with uniform brown pigmentation occasionally with transversal whitish stripes; prostomium rounded to rectangular with facial tubercle, a pair of biarticulate palpi, and bearing three antennae, with the median antenna frontally inserted; six pairs of enlarged tentacular cirri; pharynx without papillae or jaws; prolonged neuropodial lobes; notopodia and notochaetae absent from segments 1 to 5; furcated and capillary simple notochaetae; composed neurochaetae. Remarks. Villalobos-Guerrero & Harris (2012) have reinstated Oxydromus over Ophiodromus because the former was erroneously regarded a junior homonym of Oxydromus Schlegel, 1854 (Aves, Gruiformes, Rallidae), which was an incorrect subsequent spelling of Ocydromus Wagler, 1830.
