Oribatella (Oribatella) foliata Krivolutsky, 1974

Morphological features ( Figure 4a -h ). Body length: 593 (590–600) μm, body width: 394 (390–400) μm (n = 10). Rostral, lamellar, and interlamellar setae barbed; lamellae large, lamellae cusps extend as far as front end the rostrum; lamellar cuspids contiguous anteromedially, separated posteromedially, leaving prodorsum visible through oval opening; medial dens of lamellar cuspids subequal lateral dens; sensillus hardly thickened bristle-shaped, pointed, rough; notogaster with 10 pairs smooth setae; notogaster with four pairs of porose areas (Aa, A 1, A 2, A 3); femora of legs III and IV with a leaf like expansion on the edge; genito-anal formula: 6-1-2-3; legs with three claws.

Material examined. Turkey, Sakarya, the Kılıçkaya hill: 40°30’293’’ N, 30°28’153’’ E, 1223 m, 19.VI.2015, 12 inds. from soil under Abies sp. (3 of them were used for SEM)

Distribution. Oribatella (O.) foliata Krivolutsky, 1974 is known from the Palaearctic region ( Subías, 2004, updated 2020). This is the first record from Turkey.

Remarks. Oribatella (O.) foliata Krivolutsky, 1974 can be distinguished from congeners by the presence of large contiguous lamellae; inner and outer dens of lamellar cuspids of same length; sensillus hardly thickened bristle-shaped; notogaster with 10 pairs smooth setae. The body length for the species is recorded as 470-545 μm ( Krivolutsky 1974), 420–600 μm ( Weigmann, 2006) and 580-600 μm ( Shtanchaeva and Subías, 2009). In this regard, the dimensions of the type specimen are in the range of the dimensions of the Turkish specimens (590–600 µm).
