Etymology. The specific epithet is a patronym in honor of the collector of the type specimen, Italo Tapia. Diagnosis. Males are distinguished from most Ochyrocera by their color pattern ( Fig. 23 ), from O. bicolor and O. caffeeicola by the curved tip of the embolus ( Fig. 25 ).

Description. Male: Total length: 1.9; carapace length: 0.8; carapace width: 0.78.

PROSOMA: Carapace pyriform, narrowing abruptly anteriorly; shiny, yellow-green with grayish-brown longitudinal bands laterally and a small speck behind the PLE; pars cephalica slightly elevated; fovea greenish ( Fig. 23 ). Sternum light yellow-green, with wide, grayish-brown lateral bands; as long as wide; with extremely long setae. Endites light yellow apically suffused with grayish-brown; labium light yellow, suffused with dark gray; notch. Clypeus sloping with grayish-brown sputter medially; high (4x PME). Chelicerae light yellow; apically with blueish tinge; promargin with one large tooth apically, followed by a series of five teeth attached to the lamina; retromargin without denticles ( Fig. 26 ). EYES: Six eyes surrounded by black pigmentation about equal size; PME rounded, contiguous; PME-ALE slightly separated; ALE rounded contiguous with PLE; PLE rounded ( Fig. 23 ). OPISTHOSOMA: Elongated-oval; light yellow with dark brownish pattern ( Fig. 23 ); with long whitish setae; tracheal spiracle half way between epigastric furrow and spinnerets. LEGS: Greenish; tip of appendages dark greenish-blue; metatarsus and tarsus with white rings pigmentation appearing as pseudosegmentation; leg formula 1423; legs total length: I: 11; II: 7; III 5.8; IV: 8.1. GENITALIA: Palpal femur long; palpal patella greenish-blue; palpal tibia not enlarged basally; with two dorsal, two retrolateral trichobothria ( Fig. 25 ). Cymbium conical with squared extension prolaterally ( Fig. 25 ); apical apophysis triangular bearing cuspule at its apical end ( Figs 24, 25 ). Bulb oval ( Fig. 24 ). Embolus elongated, flexed at base and projecting forward, flagellum-liked; apically dark and bent ( Fig. 25 ); sperm duct narrowing 1/3 from beginning to the tip of embolus, with one loose loop ( Figs 24, 25 ).

Female: Total length: 1.9; carapace length: 0.7; carapace width: 0.6. PROSOMA: Carapace as in male; pars cephalica slightly less elevated. Sternum, endites, labium and clypeus as in male. Chelicerae whitish; apically with purplish tinge; promargin one large tooth apically, followed by a series of six teeth attached to the lamina; retromargin without denticles. EYES: As in male. OPISTHOSOMA: As in male. LEGS: As in male; leg formula 1423; legs total length: I: 7.1; II: 4.6; III: 4.1; IV: 5.6; palpal patella, distal half of tibia half and tip of tarsus purple. GENITALIA: Epigynal area somewhat swollen, with two dark marks ( Fig. 27 ). Internal genitalia with two rounded spermathecae, V-shaped sclerotization and a membranous middle section ( Fig. 28 ).

Distribution. Ecuador: Cotopaxi, Santo Domingo de las Tsáchilas and Los Ríos Provinces.

Natural history. Collected in cloud forest, a low evergreen montane forest and a humid tropical forest, altitudinal range from 100–2000m.
