| abstract | Oppioid oribatids taken from soil samples in Switzerland are recorded. There are 15 species, of which 6 are new for science and one of them also represents a new genus: Paramedioppia gen.n. (Oppiidae). The following 5 new combinations are proposed: Berniniella conjuncta (Strentzke) comb.n. et stat.n. = Oppia sigma conjuncta Strentzke, 1951; Berniniella hauseri (Mahunka) comb.n. = Oppia hauseri Mahunka, 1974; Berniniella serratirostris (Golosova) comb.n. = Oppia serratirostris Golosova, 1970; Dissorhina signata (Schwalbe) comb.n. = Oppia signata Schwalbe, 1989; Lauroppia maritima (Willmann) comb.n. = Oppia maritima Willmann, 1929; 1 species is placed in synonymy: Oppiella rafalskii Opłotna & Rajski, 1983 = Berniniella hauseri (Mahunka, 1974): syn.n. In addition 2 species (still not recorded for Switzerland) are discussed, in this way a total of 17 oppioid species are considered. Morphological and distributional data of 11 species are provided and the nature of relationships and some additional morphological characters are discussed. |
