- Selenops bifurcatus Muma, 1953: 20, fig. 35 (misidentification: ♀ only).
Holotype female: Oricuajo, Costa Rica, Biolley and Tristan (MCZ).
This species is named after the type locality, Oricuajo, and is to be treated as a noun in apposition.
Females can be separated from other species by the epigynum which has a conspicuous angular median septum located in the center of the epigynal plate, and by the epigynal pockets, and the internal ducts which have two branches (Figs 85–86). Males unknown.
Holotype female: Color: carapace dusky orange with white setae; sternum light yellow; chelicerae same color as carapace, with dusky longitudinal lateral stripes and one dusky area in the center, not extending all the way to the top of the chelicerae; maxillae dusky yellow brown, darker on sides; abdomen dorsally grey to cream-colored with dark laterocaudal festoon; legs light yellow, darkening distally, with annulations on anteroventral faces of anterior femora. Carapace:0.95 times longer than broad. Eyes:AER nearly straight; PER recurved; PME larger than AME, PLE largest, ALE smallest; eye diameters, AME 0.15, ALE 0.03, PME 0.18, PLE 0.30; interdistances AME-PME 0.10, PME-ALE 0.28, ALE-PLE 0.30. PME-PME 1.00. ALE-ALE 1.83; ocular quadrangle AME-AME 0.38, PLE-PLE 1.80. Legs:leg formula 4321 (Muma, 1953); spination not available, legs completely disarticulated. Mouthparts:chelicerae with stout setae medially and anteriorly; maxillae longer than broad, with tuft of conspicuous setae distally; labium distally rounded. Abdomen:without terminal setal tufts. Epigyne:angular to quadrate median lobe, truncate posteriorly, epigynal pockets present, genital openings located at anterolateral margins of median lobe; internally, ducts large, branching into two heavily sclerotized lateral branches, fertilization ducts located posterolaterally and directed posteriorly, small posterodorsal fold present, does not cover ducts (Figs 85–86). Dimensions: Total length 10.45. Carapace length 3.60, width 3.80. Abdomen length 6.85, width 4.65.
All that is known of this species' natural history is that it has been collected with Selenops bifurcatus.
Known only from the type locality (Map 8).
