Materials Examined
Type material. Male holotype from Ecuador, Cotopaxi Province: Otonga Biological Reserve, 04–07 September 2014, sifting litter, Berlese extraction, N. Dupérré, E. Tapia and C. Tapia (QCAZ). Two female paratypes, same data. EXAMINED. Other material examined.Ecuador: Cotopaxi Province, San Francisco de Las Pampas, Casa César Tapia (00.42415°S78.95719 °W), 1426 m, 5 November 2013, 1♂2 ♀, sifting litter, C. Tapia, C. Tapia (MECN).
Etymology
Etymology. The specific epithet is a Latin noun in apposition in reference to the rhinoceros horn-shaped cuspule of the male cymbial apophysis.
Diagnosis
Diagnosis. Males and females can be distinguished from all Ochyrocera by their color pattern (Fig. 15). Males can be diagnosed by their unique horn-shaped cymbial cuspule (Fig. 14); females can be diagnosed by their curved spermathecae (Fig. 17).

Sternum light yellow, slightly suffused with purplish tinge; as long as wide. Endites light yellow suffused with purplish tinge; labium light yellow suffused with purplish tinge; notch. Clypeus sloping; short, diameter of PME. Chelicerae light yellow; promargin with a series of seven teeth attached to the lamina; retromargin without teeth. EYES: Six contiguous eyes surrounded by black pigmentation about equal size (as in female Fig. 15); PME elongated oval; ALE rounded; PLE rounded. OPISTHOSOMA: Oval; uniformely green-purplish color; tracheal spiracle half way between epigastric furrow and spinnerets.

Cymbium with squared extension prolaterally (Fig. 14) and an elongated, curved, apical apophysis bearing horn-shaped cuspule at tip (Figs 13, 14). Bulb oval (Fig. 13). Embolus elongated, flexed at base and projecting forward with basally transparent point and dark spine-like tip; sperm duct slightly narrowing from beginning to the tip of embolus, with one tight loop (Figs 13, 14). Female: Total length: 1.2; carapace length: 0.6; carapace width: 0.4.
PROSOMA: Carapace ovoid; narrowing gradually anteriorly; shiny, light yellow with purplish pattern; pars cephalica flat; fovea not visible (Fig. 15).
