Description
Medium to large spiders characterized by an anteriorly truncated carapace that is highest in the region of the posterior lateral eyes. The lateral sides are steep, and the chelicerae are large, much longer than the clypeus width. The cheliceral furrow bears three teeth. The sternum is longer than wide, and the labium is longer than wide.4
The legs are strong, with the front leg being the thickest and strongest. The tarsi and metatarsi have thick scopulae on the last three leg segments.4
