Etymology. The specific epithet is a noun in apposition taken from the type locality, Los Ríos Province, Ecuador.
Diagnosis. Males are distinguished from most Ochyrocera by their unique color pattern (Fig. 33) and by the two twists in the male embolus (Fig. 35) from O. sandovalae by their shorter embolus not reaching the cymbium (Fig. 34).
Description. Male: Total length: 2.0; carapace length: 0.8; carapace width: 0.8.
PROSOMA: Carapace pyriform, narrowing abruptly anteriorly; shiny, yellow with brownish median bands and two lateral blackish spots; pars cephalica slightly elevated (Fig. 33). Sternum light yellow, suffused evenly with dark gray; as long as wide; with extremely long setae. Endites light yellow; labium light yellow, suffused with dark gray; notch. Clypeus sloping with wide, blueish-gray band medially; high (4x PME). Chelicerae light yellow; apically with blueish tinge; promargin one large tooth apically, followed by a series of seven teeth attached to the lamina; retromargin without denticles. 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. 33). OPISTHOSOMA: Cylindrical; light yellow with dark brownish pattern (Fig. 33); tracheal spiracle half way between epigastric furrow and spinnerets. LEGS: Greenish; apical 1/3 of femur, patella, tibia, metatarsus and tarsus dark greenish-blue; metatarsus and tarsus with white rings pigmentation appearing as pseudosegmentation; leg II and IV missing; legs total length: I: 13; III: 6.5. GENITALIA: Palpal femur long, tip with blueish mark (Fig. 35); palpal patella greenish-blue; palpal tibia not enlarged basally; with two dorsal, two retrolateral trichobothria (Figs 34, 35). Cymbium conical with lobed extension prolaterally (Fig. 35); retrolateral apophysis elongated bearing cuspule at its apical end (Figs 34, 35). Bulb spherical (Fig. 35). Embolus elongated, flexed at base and projecting forward, flagellum-liked, with two twists basally, apically darker (Fig. 35); sperm duct narrowing 1/2 from beginning to the tip of embolus with one loose loop (Figs 34, 35).
