A new Zelotes from Greece 59 Female (Paratype) Measurements. Body length 6.72, prosoma length 3.08, width 2.32, opisthosoma 3.49. Colour. General appearance very similar to male. Legs. Leg spination pattern (only segments bearing spines listed): femur: I d 1-1-0, p 0-0-1; II d 1-1-0, p 0-0-1; III d 1-1-0, p 0-1-1, r 0-1-1; IV d 1-1-0, p 0-1-1, r 0-1-1; patella: III r 0-1-0; tibia: III p 1-1-1, v 2-2-2, r 1-1-1; IV p 1-1-1, v 2-2-2, r 1-1-1; metatarsus: II v 2-0-0; III p 1-2-2, v 2-2-1, r 1-1-2; IV p 1-2-2, v 2-2-1, r 1-2-2. The female shows only some minor differences to the male: 1) Cheliceral dentition as in the male but with left chelicera possessing one additional minute retromarginal tooth situ- ated closer to fang socket (illustrated with a dashed line in Fig. 3c). 2) Leg spination shows a minor deviation from the male with the female possessing one prolateral spine on fe- mur I not seen in the male investigated. 3) Posterior lateral spinnerets with six piriform spigots (one less than in male). Intraspecific variation in these measures is unknown as only one specimen of each sex is available at present. Epigyne/vulva. Anterior epigynal margins with distinct pockets, medially interrupted (Figs 5a, 6a). Lateral epigynal margins slightly curved. Copulatory ducts with transverse dorsal curves and with lateral glandular heads, then medially looped and continuing as vertical tubes towards the recepta- cles (Figs 5b, 6b). Receptacles large, circular, and separated by ¼ of their diameter. Distribution. Mainland Greece, known from the type locality only.
