Figs 2–13

Agraecina pr. hodna: Stefanovska et al. 2008: 37 .

Type material. Holotype ♂, FYR Macedonia, Skopje, Maxari (240 m a.s.l.), grass vegetation, 02.X.2004 . Paratypes: 1 ♀, same data as for the holotype ; 1 ♂, 19.IX.2004, also from Maxari ; 1 ♂, Skopje, Karpoš (253 m a.s.l.), grass vegetation, 23.VI.2004 (all leg. D. Stefanovska) .

Etymology. Derived from the Roman name of the city of Skopje - Scupi.

Diagnosis. Somatic characteristics of the new species correspond to those of the genus, but the genitalia differ from all other known species of the genus. Morphologically, the new species most closely resembles A. hodna Bosmans, 1999 and A. lineata (Simon, 1878) , but the male is distinguished by the slender embolus, median apophysis with well-defined hook apically and thicker tibial apophysis ( Figs 4, 5 , 10, 11 ); the female can be distinguished by the median septum strongly narrowing posteriorly, and the distinct curved and oblique spermathecae ( Figs 8, 9 , 12, 13 ).

Description. Male holotype: Total length 4.68; prosoma, length 2.16, width 1.80; sternum length 1.36, width 1.08; opisthosoma, length 2.52.

Carapace yellowish, with anastomosing, radiating stripes ( Fig 2 ). All eyes subequal, except ALE whose diameter is about 30% larger than that of other eyes. AME almost touching, separated from ALE by 1/2 their diameter. Clypeus slightly larger than diameter of AME. Chelicerae yellow, with three teeth along promarginal cheliceral rim, middle one largest, two teeth on retromarginal rim. Abdomen grey to pale grey ( Figs 2, 3 ). Legs yellowish to yellow-brown ( Figs 2, 3 ). Leg spination - fe: I p 2 d 4; II p 1 d 4; III p 1 d 4; IV p 3 d 2 r 3; pt: I d 1; II d 1; III p 1 d 1; IV p 1 d 1; ti: I p 3 v 4; II p 2 v 4; III p 2 d 2 r 2 v 3; IV p 4 d 2 r 2 v 3; mt: I p 2 r 1 v 2; II p 2 r 1 v 2; II p 3 r 3 v 4; IV p 4 r 4 v 4. Leg formula 4123, measurements as in Table 1 .

Male palp ( Figs 4, 5 , 10, 11 ): Tibial apophysis well presented, pointed. Median apophysis with long apical part curved as hook. Embolus oblique, long, thin.

Female paratype: Total length 5.04; prosoma, length 2.52, width 2.16; sternum length 1.26, width 1.08; opisthosoma, length 2.52. All characters as described for male ( Figs 6, 7 ). Leg measurements as in Table 2 .

Epigyne and vulva ( Figs. 8, 9 , 12, 13 ): with well-defined median septum, greatly narrowing posteriorly. Copulatory openings wide, sperm ducts arcuate, spermathecae curved and oblique.

Distribution. Known only from the type series localities within the city of Skopje ( Fig. 1).
