Description

[edit]

Body size ranges from 18 to 33 mm.[3]

The upper surfaces are brownish-black to reddish-brown with the sternum and coxae of the third and fourth legs paler as well as the lung opercula and spinnerets. The eye area is short. The posterior row of eyes is straight to slightly procurved. The median eyes are almost round with their distance apart at least double their distance from the lateral eyes, which are obliquely oval and a little smaller than the anterior laterals.[3]

The fovea is broad. The chelicerae are anteriorly narrowed with the cheliceral furrow having two rows of teeth. The sternum has four sigilla. The abdomen lacks an abdominal shield. The tibia III is excavated dorsally at the base, saddle-shaped with a bare patch posteriorly among rows of spinules.[3]
