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°S 78.95719°W ), 1426 m , 5 November 2013 , 1♂ 2♀, sifting litter, C. Tapia, C. Tapia ( MECN ). Etymology. The specific epithet is a Latin noun in apposition in reference to the rhinoceros horn-shaped cuspule of the male cymbial apophysis. 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 ). Description. Male : Total length: 1.0; carapace length: 0.5; carapace width: 0.4. PROSOMA: Carapace ovoid; narrowing gradually anteriorly; shiny, light yellow with purplish pattern (as in female Fig. 15 ); pars cephalica flat; fovea not visible. 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. LEGS: Light yellow; leg formula 4123; total length: I: 2.1; II: 2.0; III: 1.6; IV: 2.4 GENITALIA: Palpal femur long; palpal tibia enlarged basally ( Fig. 14 arrow); with two dorsal trichobothria ( Fig. 13 ). 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. FIGURES 13–17. Ochyrocera rinocerotos sp. n. Male 13–14. Female 15–17. 13. Palp, retrolateral view. 14.

PROSOMA: Carapace ovoid; narrowing gradually anteriorly; shiny, light yellow with purplish pattern; pars cephalica flat; fovea not visible ( Fig. 15 ). Chelicerae, light yellow; promargin with a series of six teeth attached to the lamina; retromargin without denticles. Sternum, endites and labium: as in male. OPISTHOSOMA: Globular; uniformly green-purplish ( Fig. 15 ); tracheal spiracle half way between epigastric furrow and spinnerets. LEGS: same as male; leg formula 4123; total length: I: 2.2; II: 1.8; III: 1.4; IV: 2.4. GENITALIA: Epigynal region swollen with small, curved median sclerotization ( Fig. 16 ).
