), the carapace high in lateral view in both sexes, the chaetotaxy formula 1.1.1.1, and the absence of a trichobothrium on metatarsus IV. The male palp is characterized by the modified tibia, the distal suprategular apophysis moderately long, an elongated and often curved radix with a relatively short embolus. The female is diagnosed by the compact, well-sclerotized, protruded epigynum; openings covered by an overhanging ventral plate, the welldeveloped dorsal plate, as well as the subspherical receptacles.
