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.
