Coelotes sinopensis sp. n

Material: Holotype ♂, Turkey, Sinop Province, Sarıkum District (42°0ʹN, 34°56ʹE), 17.11.2011 . Paratypes: 2♀, 1 juv.♂ and 27 juv: 1♀, Sinop Province, Sarıkum District , 24– 26.5.2012 ; 1♀, Sinop Province, Sivrice hill (41°48ʹN, 35°01ʹE), 08.11.2013 ; 1 juv.♂, same locality, 08.11.2013. (leg. T. Danışman) . 27 immature, Sinop Province, Sarıkum District , 08.11.2013 .

Etymology: The specific name is a noun in apposition taken from the type locality.

Diagnosis: The male of the new species differs from all other congeners by the shape of the palpal tibial apophysis and patellar apophysis. The male of the species is distinguished from other congeners by a finger-like patellar apophysis, a typical tongue-shaped retrolateral tibial apophysis, and a turned up conductor lamella. Likewise, the female of the new species has slightly convoluted distinctive spermatechae and typical vulvae. The female differs by having relatively triangular and relatively long epigynal teeth.

Description: Male (holotype). Total length 8.1, Carapace 4.2 long, 2.1 wide. Abdomen 3.9 long, 2.4 wide. Carapace elongated, reddish brown, moderately narrowed in ocular area ( Figure 1 ). Chelicerae with three promarginal and three retromarginal teeth. Legs yellow, long, and strong. Leg formula IV, I, II, III. Leg measurements (n = 1): I 13 (3.2, 1.6, 3.1, 3.0, 2.1), II 11.1 (2.9, 1.3, 2.2, 2.8, 1.9), III 10.6 (2.7, 1.3, 2.2, 2.8, 1.6), IV 14 (3.5, 1.5, 3.4, 3.9, 1.7). Anterior eye row slightly procurved and posterior eye row procurved. AME smaller than ALE, PME nearly equal PLE. Abdomen gray, with distinct pattern. Palp: tibial apophysis tongue shaped. Median apophysis large, circular and spoon-like, and extended towards the top. Patellar apophysis thin and not blunt, with finger-like appearance. Conductor consists of two parts. Tip of conductor lamella curved upwards, and beak shaped. Dorsal apophysis of conductor triangular. There is a cymbial furrow ( Figures 2–4 ).

Female. Total length 10. Carapace 5.1 long, 2.4 wide; Abdomen 4.9 long, 3.0 wide. Coloration and texture as in the male. Leg formula IV, I, II, III. Leg measurements (n = 2): I 12.5 (3.6, 1.5, 3.1, 2.8, 1.5), II 10.9 (3.1, 1.4, 2.6, 2.5, 1.3), III 9.9 (2.9, 1.3, 2.2, 2.3, 1.2), IV 13.8 (3.9, 1.6, 3.4, 3.4, 1.5). Epigynal median plate (atrium) a little longer and rectangular. Epigynal teeth relatively triangular, short, situated on the side of the atrium. Spermathecae relatively slightly prolonged, articulated, not strongly convoluted. Spermathecal heads touch each other at the top. Fertilization ducts small ( Figures 5 and 6 ).

According to the palp and epigyne conformation, the new species clearly belongs to the genus Coelotes Blackwall 1841 . Coelotes sinopensis sp. n. belongs to the “ atropos group” and is similar to C. atropos (Walckenaer, 1830) and C. phthisicus Brignoli, 1978 . In this group, females have partly reduced epigynal teeth and copulatory ducts; males have a broad patellar apophysis, a small tibial apophysis, and a conductor dorsal apophysis.
