TYPES: Male holotype from Colombia: Valle del Cauca, Cali, Chorro de Plata, 1402 m, 3.34472°, -76.60138°, Mar. 04, 2012, Natalia Muriel Triana and Antonella Sardi, deposited in ICN 5269, PBI_OON 42225; same data, 1 male and 1 female paratypes deposited in ICN, PBI_ OON 50043; same data, Jan. 11, 2012, Natalia Muriel Triana and Antonella Sardi, 2 females paratypes deposited in ICN 5268, PBI_OON 42239; same data, 1 male paratype deposited in ICN, PBI_OON 50042.

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males can be distinguished by the shape of the copulatory bulb, with embolus with basal projection in dorsal view (figs. 58D–F, 63C, D). Females are similar to those of O. truncata , O. labarquei , and O. campana but can be differentiated by subtle details of genitalia, such as the shape of the anterior portion of the anterior receptaculum and the internal pockets (figs. 51, 60C, 61C, 64A).

MALE (PBI_OON 42225): Total length 1.24. Habitus as in figure 47A–C. CEPHALOTHO- RAX: Carapace as in figures 47A, B, 48A. Clypeus as in figure 48A, D. Eyes as in figure 48B, C. Labium rectangular. Endites anteriormedian part with one short toothlike projection. ABDOMEN: Pale yellow. LEGS (fig. 50A–D): Patella plus tibia I shorter than carapace. Leg spination, metatarsi: IV d0-0-1; p0-0-1; r0-0-1. GENITALIA: Bulb tapering apically; embolus dark, simple, with one conical projection at base; sperm duct coiled, with many loops (figs. 58D–F, 63C, D).

FEMALE (PBI_OON 42225): Total length 1.28. Habitus as in figure 47D–F. LEGS: Yellow; patella plus tibia I longer than carapace. Leg spination, metatarsi: IV d0-0-2; p0-0-1; tarsal organ, claws, setae as in figure 49. GENITALIA: External pockets absent, internal pockets small; anterior receptaculum with massive lateral projections; posterior receptaculum absent, posterior apodeme formed by entire plate (figs. 60C, 61C, 64A).

DISTRIBUTION: Known from Valle del Cauca and Quindío, Colombia (map 6).
