Abstract
This study aims to review the species of Oribatula s. str. Berlese recorded in Romanian fauna, according to the most recent monographs and catalogues, but taking the original description and/or subsequent mentions into account, as well. Rich faunistic material was examined for this purpose, collected from various ecosystem types and from most regions of the country. Six species are analyzed from a morphological and biometrical point of view. In this context, reasons to consider Oribatula amblyptera Berlese, 1916 and O. sitnikovae Iordansky, 1991 as valid species are pointed out. A brief description and illustration of each species are given, along with data on their local distribution and ecology. An identification key is proposed.
Highlights
Oribatula Berlese, 1896 is a cosmopolitan genus, about 70 % of its species having a wide or limited distribution within the Palaearctic region (Subias 2004, 2012)
More data regarding the examined material are given for each species
As in other studies of comparative morphology, classical methods were used in this case
Summary
Oribatula Berlese, 1896 is a cosmopolitan genus, about 70 % of its species having a wide or limited distribution within the Palaearctic region (Subias 2004, 2012). More than 60 % of Oribatula species were described in the last three decades. Balogh (1972), Bulanova-Zachvatkina (1975), Balogh and Balogh (1992), Weigmann (2006), Bayartogtokh (2010) consider Oribatula and Zygoribatula Berlese, 1916 as distinct genera. According to Berlese (1916) and Subias (2004, 2012) Zygoribatula and Oribatula s. Were listed, two of them being currently synonyms (Subias 2004, 2012) of other previously described species (O. venusta Berlese, 1908 and Zygoribatula saxicola Kunst, 1959, included in the genus Oribatula). In this study a comparative analysis of Oribatula species recorded in Romanian fauna is carried out, using biometrical characters in addition to morphological characters
