Female

Length of body (excluding gnathosoma) 277, width 183.

Dorsum

Dorsal shields with oval and polygonal dimples, each dimple generally contains 16–25 vacuoles, a few with eight vacuoles. Fossettes on dorsal shields as illustrated. Propodosomal shield pointed anteriorly, 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, recurved and bushy. Dimensions of setae as follows: υi 5 υe 5 sci 23, sce 5 c 1 20, c 2 27, d 15 d 2 23, e 15 e 2 27, f 1 40, h 15 h 2 30. Distance between setae: υi–υi 33, υe–υe 70, υi–υe 33, sci–sci 133, υe–sci 37, sce–sce 167, sci–sce 37, c 1 –c 1 70, d 1 –d 1 60, c 1 –d 2 63, c 1 –d 1 50, d 2 – d 2 177, d 1 – d 2 60, e 1 –e 1 67, e 2 –e 2 143, e 1 – e 2 50, d 1 – e 2 53, d 2 – e 2 57, f 1 –f 1 70, e 1 –f 1 30, e 2 –f 1 73, h 1 –h 1 37, h 2 –h 2 73, h 1 –h 2 17.

Venter

Humeral setae c 2 similar to other dorsals. Humeral regions without callosities. Humeral and suranal shields with similar patterns. Coxisternal shields completely fused, reticulate with punctations, except central region of posterior coxisternal shield which has only punctations. Coxisternal shields bearing 1a, 3a and 4a. Aggenital shield without dimples, with three pairs of setae, ag 2 and ag 3 subequal in length, but ag 1 slightly shorter than others. Pseudanal covers with three pairs of setae, subequal in length, ps 1 with spinules.

Legs

Leg I 177, leg II 160, leg III 153, leg IV 167. 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. v 1. v 2. v 3, v 4 absent, femur II with four setae.

Male

Not observed.

Distribution

Taiwan ( Tseng 1982).

Remarks

Oval, rectangular and triangular dorsal dimples, bushy dorsal body setae, and femur II with four setae are diagnostic characters of E. kentingensis . This species closely resembles E. anauniensis ( Canestrini, 1889) , but can be distinguished from the latter by the shape of dimples on dorsum, E. anauniensis with polygonal dimples. In the Turkish specimens, the coxisternal shields are also reticulate with punctations, as in the type species, except for central region of posterior coxisternal shield where there are only punctations. This species is a new record for the Turkish fauna.
