ETYMOLOGY: The specific name refers to the type locality.

DIAGNOSIS: Males can be recognized by the combination of a relatively short embolus and a single retrolateral tibial apophysis (figs. 133, 134), females by the y­shaped appearance of the posterior epigynal ducts (in ventral view, fig. 135).

Single, small, triangular retro­ lateral tibial apophysis (fig. 134), embolus relatively short, originating prolaterally (fig. 133).

FEMALE: Total length 4.9. Coloration as in O. renmark , except abdominal white spots almost obsolete, all metatarsi and tarsi yellow. Chelicerae, endites, and tarsal cracking as in male. Leg spination: tibiae III p0­0­0, v1p­1p­0, r0­0­0; metatarsi: III p1­0­1, v1p­ 0­1p, r1­0­0; IV p1­0­0, r1­1­0.
