Female

Holotype: length of body (excluding gnathosoma) 367, width 253.

Dorsum

Dorsal shields with almost circular dimples, each dimple consists of 9–12 irregularly scattered vacuoles, a few with four or 15 vacuoles. Surface between dimples with fine punctations. Fossettes on dorsal shields as illustrated. 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 short, subspatulate–spinulate. Dimensions of setae as follows: υi 33, υe 5 sci 30, sce 36, c 1 27, c 2 35, d 1 27, d 2 30, e 1 30, e 2 33, f 1 50, h 15 h 2 40. Distance between setae: υi–υi 43, υe–υe 113, υi–υe 43, sci–sci 180, υe–sci 43, sce–sce 223, sci–sce 50, c 1 –c 1 97, d 1 –d 1 90, c 1 –d 2 77, c 1 –d 1 60, d 2 – d 2 247, d 1 – d 25 e 1 –e 1 77, e 2 –e 2 197, e 1 –e 25 d 1 –e 2 67, d 1 –e 15 d 2 –e 2 73, f 1 –f 1 107, e 1 –f 1 43, e 2 –f 1 80, h 1 –h 1 47, h 2 –h 2 90, h 1 –h 2 20.

Venter

Humeral shields with dimples bearing vacuoles; setae c 2 dissimilar to other dorsals, slender, acute, with short spinules. Humeral regions without callosities. Coxisternal shields completely fused, reticulate with punctations, posterior coxisternal shield with large circle medially, with punctations and striations. Coxisternal shields bearing 1a, 3a and 4a. Surface on coxae punctate and faintly reticulate. Aggenital shield with dimples and vacuoles; with three pairs of setae, ag 1 and ag 3 subequal in length, ag 2 slightly shorter than others. Pseudanal covers bearing three pairs of setae, subequal in length, ps 1 thicker than others, with spinules. Humeral, aggenital and suranal shields with similar patterns.

Legs

Leg I 210, leg II 183, leg III 157, leg IV 200. 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 6-4-3-2, trochanters 1-1-2-1, coxae 2-2-2-2. Lengths of solenidia on tarsi: v 1 20, v 2 13, v 3 7, v 4 absent. Femur II with four setae.

Male

Unknown.

Etymology

The species name erzurumensis refers to the type locality, Erzurum .

Remarks

This species resembles E. anauniensis ( Canestrini, 1889) and E. kentingensis Tseng, 1982 , but differs from them in the dorsal ornamentation and the shape of setae c 2.
