Gnathosoma. Epistome with denticulate anterolateral margins, median process short and widened, with strong apical serration. Moveable digit of chelicera 55–60 long, with a large subterminal tooth very close to unidentate terminal hook, spermatodactyl 123–135 long, more than double (2.23–2.45) the length of moveable digit, progressively narrowed in distal section, truncated apically, shaped “b” like in all male specimens. Fixed digit with a subdistal tooth, a large subdistal denticle and a terminal hook, pilus dentilis clearly visible (Fig. 22, 34). Palptibiae without any processes.

Legs. Tarsus II with one spur-like seta p11 and opposite anterolateral apophysal spur; apophysal spur robust distinctly larger than pl1 (Fig. 23). Femur II with large and finger-like spur-like process; genu and tibia each with a small ventral distally truncated processes (Fig. 24). Femur IV with two distinct processes on ventral side, smaller one located medially, larger one located terminally (Fig. 25).

Etymology. The species is named after the type locality, Turkey.

Notes. Onchodellus turcicus sp. nov. has characteristic features in the genus Onchedellus, such as two distinct processes on femur IV and well developed distal processes in males. It is similar to O. montivagus Mašán, 2007 in some characters, such as longer dorsal setae, well reticulated ventral shields and 14 pairs of setae on lateral and ophistogastric region, longer and distally tapered spermatodactyl (more than double the length of the moveable digit), telofemur IV with uniform setae in males. There are important differences between these two species, such as larger body size (593¯ 653 in O. turcicus, 515¯ 550 in O. montivagus), length of dorsal setae J4 and J5 (J4 60¯75, J5 45¯ 55 in O. turcicus, J4 56¯62, J5 37¯ 42 in O. montivagus), apical tips of peritremes (reaching base of z 1 in O. turcicus, not reaching base of z 1 in O. montivagus), process of tibia II (truncated in O. turcicus, pointed O. montivagus), spermatodactyl length (more than double the length of movable digit in O. turcicus, three or four times as long in O. montivagus), opposite anterolateral process distinctly larger than pl 1 in O. turcicus (slightly larger in O. montivagus), two distinct processes on femur IV in O. turcicus (absent in O. montivagus).
