Review and resolution of some nomenclatural issues regarding the genus Psoroptes (Acari: Psoroptidae), scab-mites of domestic and wild mammals.
Some classifications recognize a number of species in the scab-mite genus, Psoroptes, mites that are of considerable importance in livestock production and veterinary medicine. However, modern studies suggest that populations from some host species are not morphologically or genetically distinct, creating taxonomic confusion with older names, which treated mites from different hosts as separate species. We review the taxonomy and nomenclature of the genus and the two oldest binomens, most recently known as Psoroptes ovis and Psoroptes equi. Prior authors have attributed these names to various authorities, with most attributing both names to Hering (Nova Acta Phys-Med Acad Caesar Leopold-Carol Nat Curios 18(2):573-624, 1838). In particular, the priority between these names was recently a point of contention, with P. ovis being treated as junior synonym of P. equi. A review of all relevant nineteenth and twentieth century publications indicates, however, that these binomens should be cited as P. ovis (Viborg in Veterinair-Selskabets Skrifter 2:139-152, 1813) and P. equi (Raspail in Bull gener Theraput Med Chir 7:169-184, 1834), with the former having priority over the latter assuming their conspecificity. We also clarify attribution of the authorship and the type species of the genus Psoroptes.
