TYPES: Male holotype, male paratype, female allotype, and female paratype from Berlese sample of overflow of debris on ground from split tree hole 6 ft up on the trail to the dam on Nigua Creek, Almirante, Bocas del Toro, Panama (Mar. 25, 1959; H. Dybas), deposited in FMNH (PBI_OON10395) .

DIAGNOSIS: Males resemble those of the Costa Rican species R. lucha in having a triangular palpal apophysis, but have a much more sinuous embolus (figs. 263–266); females also resemble those of R. lucha in having an asymmetrical anterior genitalic process, but that process is shorter and is situated on a much shorter base (figs. 272, 273).

Sternum with anterior channels, surface smooth, without pits, microsculpture; setae densest laterally. Labium anterior margin deeply incised. Endites with bipartite terminal lobe, proximal portion with two modified setae. Palpal apophysis triangular, basal portion of embolus highly sinuous; cymbium not fused with bulb.

FEMALE (PBI_OON 10395, figs. 270–273): Total length 1.17. Labium anterior margin indented at middle. Anterior genitalic process asymmetrical, situated on short base.
