Length of gnathosoma 46 – 48; subcapitulum with two pairs of subcapitular setae (m and n), m 15 – 16, n 9 – 11 and two pairs of adoral setae, or 1 and or 2; palpi five segmented, palp tarsus with five simple setae + one tridentale eupathidium + one solenidion; palp tibia with two setae + one accessory claw + one well-developed claw; palp genu with two setae; palp femora with three setae; palp trochanter without setae.

Dorsum ( Figure 6a ) — Dorsal shields with thick reticulum. Propodosomal shield with three pairs of setae, one pair of eyes located between setae ve and sci. Setae sce located on small auxiliary shields. Central shield with two pairs of setae, c 1, d 1; setae c 2 on humeral shield ventrolaterally; marginal shield with setae d 2; median zonal shield divided and with setae e 1; lateral zonal shields with setae e 2; intercalary shield entire, with setae f 1; suranal shield entire, with two pairs of setae, h 1 and h 2. Dorsal body setae sword shaped with a few faint serrations and all hysterosomal setae terminally expanded and serrated ( Figures 6 h-i). Dimensions of setae as follows: vi 26 – 32, ve 36 – 47, sci 16 – 19, sce 32 – 36, c 1 29 – 33, c 2 30 – 36, d 1 28 – 34, d 2 31 – 35, e 1 31 – 34, e 2 33 – 38, f 1 37 – 44, h 1 17 – 23, h 2 39 – 47; distances between dorsal setae: vi -vi 15 – 17, ve -ve 30 – 41, vi -ve 22 – 25, ve -sci 19 – 24, sci -sce 10 – 12, sci -sci 65 – 76, sce-sce 75 – 99, sce-c 1 23 – 31, c 1 -c 1 42 – 50, c 1 -d 1 35 – 40, c 2 -c 2 129 – 157, d 1 -d 1 39 – 48, d 1 -d 2 36 – 42, d 1 - e 1 22 – 30, e 1 - e 1 31 – 35, e 1 - e 2 22 – 27, e 1 -f 1 19 – 24, f 1 -f 1 50 – 59, f 1 -h 1 21 – 26, h 1 -h 1 20 – 25, h 1 -h 2 8 – 10, h 2 -h 2 40 – 48; ratios vi / vi -vi 1.6 – 1.9, c 1 / c 1 -c 1 0.6 – 0.7, d 1 / d 1 -d 1 0.7 – 0.8, e 1 / e 1 - e 1 0.9 – 1.0, f 1 / f 1 -f 1 0.7 – 0.8.

Venter ( Figure 6b ) — Ventral cuticle transversely striate between coxisternal regions II-III; coxisternal shields I-II and III-IV are surrounded by longitudinal striae. Lengths of setae: 1a 13 – 15, 3a 14, and 4a 12 – 13 and ratio 1a: 3a: 4a 1.2:1.2:1. Aggenital area with three pairs of setae, ag 1 11 – 14, ag 2 12 – 15 and ag 3 18 – 24; anogenital valves with three pairs of pseudanal setae, ps 1 7, ps 2 7 – 9 and ps 3 14 – 17.

Legs ( Figures 6 c-f) — Length of legs: leg I 109 – 116, leg II 90 – 99, leg III 87 – 97, leg IV 98 – 109. Setal formulae of leg segments as follows: coxae 2, 2, 2, 2; trochanters 1, 1, 2, 1; femora 6, 5, 3, 2; genua 3(κ), 3(κ), 0, 0, tibiae 7(’, ’ p), 6(’ p), 6(’ p), 6(’ p); tarsi 15 (2 ω), 11 (2 ω), 9 (2 ω), 9 (2 ω).

Material examined: 5 males from litter and soil under Pinus sp. , Turkey, Hatay, Payas Village (36°45’32"N, 36°11’51"E, 4 m), 22 May 2014 .

This species was described by Akyol and Koç (2007) from litter under Astragalus sp. , Crateagus sp., Quercus sp. Verbascum sp. and Populus sp , in Afyonkarahisar and based on a female ( Akyol and Koç 2007). Male specimens were described from litter and soil under Pinus sp. Males of this species exhibit the same features of the female descriptions, except that the male tarsi I-IV are with two solenidia instead of one solenidion in female; length of body and dorsal setae shorter than those of the female and intercalary shield fused (separate in the female).
