Figs. 7–17
Measurements. Body length 228–244 (holotype: 244), body width 104–116 (holotype: 114).
Prodorsum (Figs. 7, 10–13). Rostrum divided by deep median incision. Rostral setae smooth, 13 in length, arched inwards. The costulae long, parallel, widened at their median parts and reaching to the median incision of the rostrum. Lamellar setae 5 in length, arising at the distal end of the costulae, situated closer to rostral setae than to interlamellar setae. Interlamellar setae minute, 2 in length and arising in anterior one-third of the interbothridial protuberance. Lamellar and interlamellar setae smooth. Bothridia well developed. Sensilla with long stalk and little dilated, strongly barbed elliptical heads.
Notogaster (Figs. 7, 10). Oval, but straight anteriorly, with one pair of prominent humeral processes. Ten pairs of notogastral setae, thick and unilaterally barbed.
Ventral side (Figs. 8, 9). Epimeral regions 3 and 4 with polygonal network, but on epimere 2 polygonal network is visible only in median part. Epimeral setal formula 3-1-3-3. Genital plate 26 in length, 28 in width, with five pairs of setae. Form and position of genital setae as shown in Fig. 9. Anal plate 38 in length, 30 in width, with two pairs of setae. Aggenital setae and three pairs of adanal setae short and thin. Distance between genital and anal plates 38. Lyrifissure iad situated in para-anal position. Adanal setae ad 1 in postanal, ad 2 in para-anal and ad 3 in preanal position.
Legs (Figs. 14–17). All legs monodactylous. Setation of leg segments is given in figures 14–17.
Material examined. YÇMP-382, soil from Pinus nigra and Quercus spp. forest, N 39°48.141’, E 034°48.742’, 1498 m, 12 May 2006, holotype, four paratypes; YÇMP-251, soil and litter from Pinus nigra and Quercus spp. forest, N 39° 48.452’, E 034°48.955’, 1455 m, 01 Dec 2005, two paratypes; YÇMP-257, as for the previous sample, N 39°48.460’, E 034°48.935’, 1460 m, 01 Dec 2005, one paratype; YÇMP-258, as for the previous sample, N 39°48.456’, E 034°48.932’, 1461 m, 01 Dec 2005, one paratype; YÇMP-386, soil from Pinus nigra and Quercus spp. forest, N 39°48.189’, E 034°48.713’, 1505 m, 12 May 2006, one paratype; YÇMP-412, as for the previous sample, N 39°48.138’, E 034°48.750’, 1569 m, 12 May 2006, eleven paratypes (three of them in the collection of L. S. Subias, Spain); YÇMP-442, soil from uncovered area, N 39°48.022’, E 34°48.557’, 1548 m; 19 June 2006, seven paratypes.
Etymology. This new species is named in honor of Prof. Dr. M. Özkan, Uludag University, Turkey, for his contribution to the knowledge of Turkish mite fauna.
Remarks. Until now, only three species of the genus Cosmogneta have been described, namely C. impedita Grandjean, 1960 from France, C. kargi Grandjean, 1963 from Germany and C. cassolai Bernini, Baratti and Avanzati, 1991 from Italy (Grandjean 1960, 1963; Bernini et al. 1991; Subias 2004).
These species, and C. ozkani, are all similar to each other but can be identified with the following key.
1. Lamellar setae present ..................................................................................................................................2
- Lamellar setae absent....................................................................................................................................3
2. All notogastral setae thick and barbed; length = 228–244 ................................................ C. ozkani sp.nov.
- The setae c2 and ps series short and thin, the remaining notogastral setae thick, apically enlarged and peni- cillate; length = 270 and 271 ................................................. C. cassolai Bernini, Baratti & Avanzati, 1991
3. All notogastral setae thin and smooth; length = 300–320 ..................................... C. kargi Grandjean, 1963
- The setae c2 and ps series short and thin, the remaining notogastral setae thick, apically enlarged and curved spatula-like; length = 270–310 ............................................................ C. impedita Grandjean, 1960
