Genus Oribatula S. Str. Berlese, 1896 (Oribatida, Oribatulidae) In Romanian Fauna Author Ivan, O. text Acarologia 2013 2013-06-28 7 2 175 184 http://dx.doi.org/10.1051/acarologia/20132086 journal article 7310 10.1051/acarologia/20132086 cc8ef700-464e-4ede-9ea0-7b94b7ce3bb9 2107-7207 4667216 Oribatula sitnikovae Iordansky, 1991 ( Figure 6 ) Literature — Iordansky (1991) , Weigmann (2006) . Material examined — 3 specimens from Rodna Mountains , 5 specimens from Calimani Mountains ( Eastern Carpathians ) (subalpine shrubs, mountain meadow respectively) .

FIGURE 5: Oribatula interrupta ( Willmann, 1939 ) : a – dorsal view; b – ventral view; scale bar: 100 µm. FIGURE 6: Oribatula sitnikovae Iordansky, 1991 : a – dorsal view; b – ventral view; scale bar: 100 µm. Diagnosis — Medium sized species (Table 1), with elongated body. Cuticle smooth, colour light yellowish. Prodorsum with narrow lamella; short thickened lines oriented medially are present at the apex of each lamella. Prodorsal setae robust and finely barbed. Sensillus short, with distal part globulous. Notogaster oval, elongated, the breadth/length ratio having a comparatively low value. The 13 pairs of notogastral setae are relatively long ( Table 2 ). Areae porosae are small, oval, typically positioned. Ventral side has the aspect and chaetotaxy characteristic for the genus. Remarks — At present, this species is considered synonym of O. interrupta ( Subias 2004 , 2012). However, a number of characters differentiate the two taxa, such as: shape of sensillus, width of lamella, absolute and relative length of notogastral setae (twice as long in O. sitnikovae ) ( Table 2 ). Distribution — NW of the former USSR ( Subias, 2004 ). O. sitnikovae has been recorded in mountain habitats, as meadows and subalpine shrubs from Calimani, and respectively Rodna Mountains (Eastern Carpathians).
