Type species: Araneus rhinura Pocock, 1899 (removed from the synonymy of Neoscona Simon, 1864 by Grasshoff, 1986: 4)

Diagnosis. Representatives of the genus Eriovixia are small to medium-sized orb-weaving spiders. This genus differs from all other araneid genera by the following combination of characters: absence of macroseta in the male pedipalp patella; absence of male coxa I hook; epigyna nearly triangular, with copulatory openings wide and opening dorsally; and by the female abdomen which extends beyond the spinnerets, and appears as a “tail”.

Description. Total length: 3.00–5.70 (females), 2.60–3.90 (males). Carapace piriform, slightly longer than wide, narrow in eye region, covered with white seta, cervical groove deep in females and inconspicuous in males, cephalic region slightly elevated in females (Figs 1, 9, 17, 25). Legs yellowish with dark annuli (Figs 1–2, 9–10, 17–18, 25–26). Abdomen triangular, pointed posteriorly (Figs 1–2, 9–10, 17–18, 25–26). Epigyna subtriangular, with rimmed scape (Figs 3–4, 11–12, 19–20, 27–28); copulatory openings situated on the dorsal surface of the scape, copulatory ducts twisted; spermathecae touching (Figs 5, 13, 21, 29–30). Pedipalpal of male with small paracymbium, median apophysis large, with one or two pointed spurs; conductor usually wide; embolus slender and short (Figs 6–7, 14–15, 22–23, 30–31); terminal apophysis present (Figs 14, 31) or fused with embolus (Figs 6, 22).
