ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males can easily be recognized by the apically prolonged palpal bulb (figs. 371, 372), females by the relatively heavy sclerotization of the entire epigastric scutum (fig. 379) and the diamond-shaped anterior receptaculum (figs. 380, 381).

Palpal spination: femur v0-0-1, patella p1-1-1, tibia p1-0-0, v0-1-0, tarsus v1- 1-2. Anterior receptaculum diamond shaped; posterior receptaculum rectangular, with distinct lumen (figs. 379–381).
