Etymology. The species name derives from the district where it was found for the first time, Peloponnisos.

Type: GREECE: Peloponnisos, Taygetos Mt , phrygana, 600 m alt: 1 ♂ holotype, 1 ♀ paratype (ptf, 15. III.97 to 06. VII.97, leg. I. Anastasiou, ZMUA G588.3 View Materials (1)) .

Other material: GREECE: Peloponnisos: Taygetos Mt , phrygana, 600 m alt: 1 ♀ (ptf, 15. III.97 to 06. VII.97, leg. I. Anastasiou, ZMUA G588.1 View Materials (1)); 1 ♀ (ptf, 09. V.97 to 05. VII.97, leg. I. Anastasiou, ZMUA G584.3 View Materials (1)); Mainalo Mt, conifer wood, 1400 m alt: 1 ♂ (ptf, 09. V.97 to 05. VII.97, leg. I. Anastasiou, ZMUA) .

Diagnosis: N. peloponnesiaca n. sp. is distinguished from its congeners by the bulging tegulum, the distinct horizontal embolus and shape and size of the tibial apophysis of the male pedipalp. It is also distinguished by the shape of the two-chambered spermathecae and the distinct central pouches that they form.

Description. Measurements ♂ (♀) n = 2 (3): PL: 2.3 (2–2.3), PW: 1.7–2 (1.3–1.5), OL: 2.5–2.9 (2.2–3.2).

♂: Red brown spiders of medium size. Abdomen light grey with characteristic lines along it. Males with large scutum. Eyes round except for slightly oblique PME. AME black, all other white with black surrounding. Anterior and posterior row of eyes straight or slightly procurved. Distance between AME closer than distance between AME and ALE. Posterior eyes equidistantly positioned. Chelicerae with dentated keel at its entire surface.

In both sexes the fourth pair of legs is longer than the first, a character that is shared with N. palaestina but not with all its congeners.

Leg spination: Fe: I d 3; II d 3; III d 5–6; IV d 5–6. Pa: I–II -; III –IV p 1 r 1. Ti: ♂ I v 2; ♀ I v 1–2; ♂ II v 2; ♀ II v 2 p 1; III –IV spinose. Me: ♂ I v 4–5; ♀ I v 4; II v4; III –IV spinose. Ta: all with dense hair .

♂ Pedipalp ( Figs 34–37 View FIGURES 34–37 ): Tegulum robust with prolateral extension of membranous corrugated surface. Embolus large, directed horizontally and with an extra fold at its end. A sclerotized apophysis (l) is situated behind embolus. Tibial apophysis expanding from retrolateral edge of cymbium to more than half its width ( Figs 35–37 View FIGURES 34–37 ). Round and short frontal part, continuing to a groove, adjusted to a lateral furrow of the cymbium ( Fig. 35 View FIGURES 34–37 ) and leading to a bifid end with an upper round lobe and a lower small and pointed tip ( Figs 36– 37 View FIGURES 34–37 ).

Epigyne ( Fig. 38 View FIGURES 38–39 ): Lateral margins oblique, narrow at apical part and widening at basal part. Compared with its congeners with similar shape of epigyne (i.e. N. excerpta , N. exornata , N. recepta , and N. ripariensis ) N. peloponnesiaca n. sp. is different by the general shape of these margins, limiting the central depression to about 2/3 of the total length of spermathecae. Therefore the latter are partly positioned above the frame that these margins form.

Vulva ( Fig. 39 View FIGURES 38–39 ): Spermathecae long with two chambers: one large, round-shaped at anterior part, connected with an extra lateral pouch and one smaller at posterior part, oval-shaped. The two are connected by a cylindrical tube.

Distribution: GREECE, Peloponnisos.
