Type material.

Holotype female: Chamela, Jalisco, México, 1.X.1989, sea level, W. Eberhard (AMNH).

Etymology.

This species is named after the type locality, Chamela, and is to be treated as a noun in apposition.

Diagnosis.

Females can be separated from all other species by the epigynum which has a median septum and epigynal pockets, and internally, the ducts are coiled at least 5 times (Figs 73-74). Males unknown.

Remarks.

It is unclear whether this is a new species or is the female of Selenops lepidus . See abover under 'Remarks' of the latter species.
