Dorsal prosoma yellow-brown, lateral margins dark, with yellow submarginal transversal light band posteriorly. Fovea and radial furrows distinctly marked. Labium and gnathocoxae yellowish-brown, both with distal parts brighter. Sternum yellowish-brown, with margin brown. Chelicerae deep reddish-brown. Legs yellowish-brown with dark spots. Dorsal opisthosoma dark brown, covered by grey hairs, opisthosoma in posterior half with dark transversal band above spinnerets.
