Diagnosis
Male (
Figure
25
) diagnosed by
Gray (
1994
)
. Females can be distinguished by the combination of the following: the enlarged, usually longer than wide, bases of the spermathecae; the lack of a clear distinction between the base and the inner spermathecae; and the rounded outer spermathecae, on the top of a short, laterally directed stalk (

Coloration: carapace cream, with dark brown median pattern and clypeal markings, and light brown median area, with slightly dark submarginal bands; chelicerae cream with an anterior brown patch; labium and endites light yellow; sternum cream with diffuse light brown patches along the anterior border; legs light yellow, with incomplete light brown rings in the base and apex of the femora, tibiae and metatarsi and a prolateral light brown patch on the patellae; abdomen dorsum light brown, clothed with whitish setae, with dark brown chevron with five markings posteriorly; abdomen venter cream, darker posteriorly.
