Eustigmaeus erzincanensis n. sp.

( Figure 10 )

Type materials

Holotype female and three paratype females from moss, Ahmediye , Erzincan, 28 April 2001.

Female

Holotype: length of body (excluding gnathosoma) 447, width 310.

Dorsum

Dorsal shields covered with circular dimples bearing vacuoles, some vacuoles more distinct than others, faint punctations between dimples. Fossettes on dorsal shown as Figure 10A . 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 smooth, swordshaped, with axial core and thin hyaline sheath, setae f 1 with a few fine and short spinules, setae h 1 similar to other dorsal setae but without core and with spinules, setae h 2 unsheathed, very short and spinulate. Dimensions of setae as follows: υi 72, υe 100, sci 23, sce 87, c 1 83, c 2 39, d 1 97, d 2 83, e 1 113, e 2 100, f 1 93, h 1 57, h 2 43. Setae sci shorter than c 2. Distance between setae: υi–υi 32, υe–υe 133, υi–υe 54, sci–sci 230, υe–sci 63, sce–sce 263, sci–sce 40, c 1 –c 1 110, d 1 –d 1 87, c 1 –d 2 117, c 1 –d 1 93, d 2 – d 2 273, d 1 – d 2 100, e 1 –e 1 153, e 2 –e 2 250, e 1 –e 2 67, d 1 –e 1 130, d 1 –e 2 107, d 2 –e 2 90, f 1 – f 1 112, e 1 – f 1 40, e 2 – f 1 113, h 1 –h 1 43, h 2 –h 2 104, h 1 –h 2 33.

Venter

Setae c 2 placed on triangular dimpled humeral shields. Humeral regions with major callosities, covered with pores, not conjunct to margins of dorsal shields, minor callosities absent. Surface on coxae faintly reticulate and densely punctate. Coxisternal shields completely divided with polygonal dimples and bearing 1a, 3a and 4a. Aggenital shield with polygonal dimples, two pairs of subequal setae. Pseudanal covers with three pairs of subequal setae. Humeral and suranal shields with similar patterns as that of dorsum.

Legs

Leg I 333, leg II 263, leg III 260, leg IV 327. Number of setae (solenidia in parentheses) on leg segments (I–IV) as follows: tarsi 14(v)-10(v)-8(v)-8(v), 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. Lengths of solenidia on tarsi: v 1 28, v 2 18, v 35 v 4 6.

Etymology

The new species name erzincanensis refers to the type locality, Erzincan .

Remarks

The new species is similar to E. erciyesiensis Doğan, Ayyıldız and Fan, 2003 . However, it can be distinguished from the latter by having setae 4a on the metasternal shield and postocular setae sci shorter than humeral setae c 2.
