Eustigmaeus jiangxiensis Hu, Chen and Huang 1996, p 319 .

Examined materials

Six females from moss and lichen on bark, Uzunoluk Forest, Oltu , Erzurum, 15 June 2001; 50 females from forest litter, Uzunoluk, Oltu , Erzurum, 25 September 2001 .

Female

Length of body (excluding gnathosoma) 463, width 310.

Dorsum

Reticulations covering dorsal shields consist of polygonal dimples. No visible fossettes on dorsal shields. Propodosomal shield with four pairs of setae and one pair of eyes. Hysterosomal shield with six pairs of setae, suranal shield with two pairs of setae. Dorsal body setae fusiform, apically pointed, slightly spinulated, with axial core and thin hyaline sheath. Setae h 1 and h 2 dissimilar to other dorsal body setae, with more spinules, without axial core and sheath. Dimensions of setae as follows: υi 33, υe 47, sci 20, sce 5 c 1 33, c 2 24, d 1 33, d 2 30, e 15 e 2 33, f 1 53, h 1 40, h 2 37. Distance between setae: υi–υi 33, υe–υe 133, υiυe 73, sci–sci 220, υe–sci 57, sce–sce 270, sci–sce 53, c 1 –c 1 97, d 1 –d 1 163, c 1 –d 2 123, c 1 –d 1 110, d 2– d 2 300, d 1– d 2 83, e 1 –e 1 130, e 2 –e 2 238, e 1 –e 2 67, d 1 –e 15 d 2 –e 2 110, d 1 –e 2 77, f 1 –f 1 80, e 1 – f 1 43, e 2 –f 1 117, h 1 –h 1 37, h 2 –h 2 97, h 1 –h 2 30.

Venter

Setae c 2 similar to other dorsals, placed on humeral shields ornamented with dimples. Humeral regions without callosities. Coxisternal shields completely divided, with polygonal dimples and bearing setae 1a and 3a, but 4a absent. Surface on coxae with polygonal dimples. Aggenital shield with polygonal dimples, two pairs of setae, ag 1 slightly shorter than ag 2. Pseudanal covers with three pairs of setae, ps 3 and ps 2 subequal in length, but ps 1 longer than others, rod-like and with minute spinules.

Legs

Leg I 310, leg II 263, leg III 267, leg IV 290. Number of setae (solenidia in parentheses) on leg segments (I–IV) as follows: tarsi 14(v)-10(v)-8(v)-7, tibiae 7(w, w p)-6(w p)-6(w p)- 6(w p), genua 4(k)-4(k)-1-1, femora 6-5-3-2, trochanters 1-1-2-1, coxae 2-2-2-2. v 1. v 2. v 3, v 4 absent.

Distribution

China ( Hu et al. 1996).

Remarks

This species is similar to E. breυisetosa ( Wood, 1966), from which it can be distinguished by the postocular setae sci which are not very diminutive. General features and details of leg chaetotaxy of Turkish specimens are as in the type species, given by Hu et al. (1996), but the first pair of pseudanal setae (ps 1) with minute spinules. This species is a new record for the Turkish fauna.
