Diagnosis. The male is easily recognized by the shape of the embolus, with a wide base and not forming a full loop. It slightly resembles E. falciger described above, but is larger and may be recognized by the lack of an outgrowth on the ventral surface of the palpal tibia and by the shorter, stouter embolus. The female has wider seminal ducts than in congeners.

Etymology. The specific name refers to the southern distribution of the species.

Description. Measurements (male/female). Cephalothorax: length 1.0/1.1–1.2, width 0.6/0.7–0.8, height 0.4/ 0.4. Abdomen: length 1.0/1.1–1.3, width 0.6/0.8–0.9. Eye field: length 0.4/0.4–0.5, anterior width 0.5/0.6–0.7, posterior width 0.6/0.7–0.8.

Male. General appearance as in Fig. 78 View FIGURES 78–83 . Very small spider. Carapace dark brown to blackish, shining, eye field black, delicately pitted, with a few brownish bristles near eyes. Clypeus clothed in colourless hairs. Chelicerae orange, promargin with two teeth, retromargin unident. Mouth parts and sternum brownish. Abdomen oval, brown, whole dorsum covered with delicate shining scutum, without hairs, venter yellowish grey or blackish with four lines formed by light dots. Spinnerets light. Legs I black with yellowish tarsus. Other legs generally brown, dorsal surfaces of femora slightly lighter, yellowish grey, basal halves of segments lighter than their distal parts. Pedipalps orange to brown, clothed in dark hairs, cymbium and bulb yellow. Tibial apophysis wider than in the majority of congeners ( Figs 81, 83 View FIGURES 78–83 ), bulb oval, without delimited proximal lobe ( Fig. 79 View FIGURES 78–83 ), with meandering spermophore, embolus stiletto-like with broad base ( Figs 80, 82 View FIGURES 78–83 ).

Female. General appearance as in Fig. 84 View FIGURES 84–86 , slightly larger than male. Carapace as in male. Abdomen with typical markings for Euophrys spp. , coloration dark grey with mosaic of small lighter patches and a few (5–6) pairs of larger light spots and chevrons along midline, dark patches fused into irregular transverse streaks on sides, venter yellowish. Legs yellowish, bases of patellae, tibiae and metatarsi brown. Epigyne very weakly sclerotized, with two shallow, slightly procurved depressions, copulatory openings situated laterally ( Fig. 85 View FIGURES 84–86 ). Internal structures simple, as in Fig. 86 View FIGURES 84–86 .
