SOME NOMENCLATURAL CHANGES FOR ACARI (IXODIDA AND ORIBATIDA)Abstract : The paper gives remarks on the nomenclatural validity of the subgenus name Segalia Dias, 1968 and the genus name Hammeriella Paschoal, 1989. In addition to this, some junior homonyms were detected among the oribatid mite genus group names and the following replacement names are proposed: Fberninia nom. nov. for Berniniella Özdikmen, 2008; Zetorchella Berlese, 1916 for Chaunoproctus Pearce, 1906 and Salvus nom. nov. for Pterobates Balogh & Mahunka, 1977. Accordingly, new combinations are herein proposed for the species currently included in these genus group names. Two family group names Zetorchellidae nom. nov. and Salvidae nom. nov. are also proposed for Chaunoproctidae Balogh, 1961 and Pterobatidae Balogh & Mahunka, 1977 respectively.
