Genus Euryopis Menge, 1868

Type species: Micryphantes flavomaculatus C. L. Koch, 1836 (= Euryopis flavomaculata)

Diagnosis. Euryopis differs from Dipoena, Lasaeola and Phycosoma by the absence of carapace spherical or rounded and by the absence of distinct cervical grooves. Euryopis presents carapace oval (Figs 1A, 2A, 3A, 4A), not modified. Differs from Guaraniella by the cymbium without deep apical notch. Differs from Audifia by the abdomen without a sclerotized ring around the spinnerets and pedicel and differs from Audifia by the not elongate carapace. Euryopis has an oval (Figs 1A, 2A, 4A, 5A) or subtriangular abdomen (see Levi 1963, Fig. 9), dorsoventrally flat (Fig. 7D), sometimes project over the carapace; blackish brown to black (Fig. 1A), sometimes with silver dots and males with sclerotized scutum on the dorsum (Figs 7A, D). The females of Euryopis have the epigynum with an oval depression (Fig. 9C); and males have a distal cymbial projection (Fig. 8A), however there are some species lacking such projection (Fig. 8D) or having it little pronounced (Figs 8B, C).
