Etymology. The specific epithet is a Latin adjective in reference to the turquoise color of the abdomen.
Diagnosis. Males and females can be distinguished from all Ochyrocera by their bright turquoise abdomen, apically with purplish chevrons (Fig. 18). Furthermore males can be diagnosed from all Ochyrocera by their unique horn-shaped cymbial apophysis (Fig. 19); females can be diagnosed by their dark spermathecae and median thumbshaped projection (Fig. 22).
Description. Male: Total length: 0.7; carapace length: 0.3; carapace width: 0.3.
PROSOMA: Carapace ovoid; narrowing gradually anteriorly; shiny, light yellow, lateral sides with purplish pattern (Fig. 18); fovea not visible. Sternum light yellow, 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 eight teeth attached to the lamina; retromargin without teeth. EYES: Six contiguous eyes surrounded by black pigmentation about equal size; PME elongated oval; ALE rounded; PLE rounded. OPISTHOSOMA: Oval; turquoise, apical end with purplish chevrons; tracheal spiracle half way between epigastric furrow and spinnerets. LEGS: Light yellow; leg formula: 4123; total length: I: 1.6; II: 1.4; III: 1.1; IV: 1.7. GENITALIA: Palpal femur long; palpal tibia with two dorsal trichobothria (Fig. 19). Cymbium extension not observed, rounded dorsally, with wide horn-shaped apical apophysis bearing cuspule at tip (Figs 19, 20). Bulb oval (Fig. 20). Embolus elongated, spine-liked, flexed at base and projecting upward; sperm duct narrowing 1/2 from beginning to the tip of embolus, with two loose loops (Figs 19, 20).
Female: Total length: 0.9; carapace length: 0.4; carapace width: 0.3.
PROSOMA: Carapace as in male. Chelicerae, light yellow; promargin with a series of seven teeth reaching the lamina; retromargin without denticles. Sternum, endites and labium: as in male. OPISTHOSOMA: As in male. LEGS: As in male; leg formula; 4123; total length: I: 1.5; II: 1.4; III: 1.2; IV: 1.7.

Internal genitalia with semi-transparent, thumbshaped projection, spermathecae dark with transparent apical end (Fig. 22).
Distribution. Ecuador: Cotopaxi and Santo Domingo de las Tsáchilas Provinces.
Natural history. Collected in moss and sifting litter between 1209–1888 m.
