The described female has a dusky orange carapace with white hairs.
The back of the abdomen is grey to cream-coloured with dark markings around the rear sides.
The female used to describe Selenops oricuajo measured 10.45 mm long, with an abdomen 6.85 mm long. Its carapace was 3.60 mm long and 3.80 mm wide, slightly wider than long. It lacked terminal abdominal hair tufts.
This spider received a new name after its specimen had long been treated as the female of another species. In 1909, a male and female from Oricuajo, Costa Rica, were described as Selenops bifurcatus; both were illustrated again in 1953. The 2011 revision reassessed that pairing.
Males and different females collected at multiple Central American localities mated and produced offspring in the laboratory, and matched for multiple gene sequences, establishing that pairing as bifurcatus. The female historically associated with that name was instead described as oricuajo. Its external genital plate has a conspicuous angular central division, and large internal ducts branch into two parts.
An extinction-risk assessment has not been added yet.
In the 2011 account, distribution records were limited to the type locality, Oricuajo. Costa Rica’s conservation authority SINAC states a policy of scientifically informed wildlife management to maintain ecological processes inside and outside protected areas. For this spider, surveys near the original locality, with documented identification and habitat observations, would help establish its distribution and conservation needs.
