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

DIAGNOSIS: Males can be recognized by the reduced abdominal scuta (figs. 867, 873) and the relatively short distal portion of the embolus (figs. 875–879), females by the procurved transverse bar situated anteriorly of a much wider epigynal atrium (figs. 888, 889).

MALE (PBI_OON 464, figs. 867–879): Total length 1.32. PME oval; ALE separated by less than their radius; PLE-PME separat- ed by less than PME radius. Endites with anterior projections beaklike, directed laterally. Leg spination: tibiae IV v0-0- 1p. Embolus relatively short, bent prolaterally at about 2/3 its length, tip bent, directed posteriorly; bulb tapering apically (figs. 875–879).

FEMALE (PBI_OON 465, figs. 880–889): Total length 1.56. Posterior eye row straight from above, procurved from front. Leg spination: tibiae IV v0-0- 1p. Transverse bar at base of anterior projection relatively short, procurved, situated anteriorly of widely oval atrium (figs. 888, 889).
