TYPES: Male holotype and female allotype taken in pitfall traps in Polylepis forest at an elevation of 3850 m on the road from Papallacta to Oyacachi in the Reserva Ecológica Cayambe-Coca, 0u169130S, 78u059360W, Napo, Ecuador (Dec. 1–2, 2009; N. Platnick, N. Dupérre´, E. Tapia, Niarchos Exped. ), deposited in QCAZ (PBI_OON 463).

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

DIAGNOSIS: Males resemble those of S. napo but have the embolus tip directed ventrally (figs. 832–836); females have the transverse sclerite at the base of the anterior genitalic projection long and boat shaped (figs. 845, 846).

MALE (PBI_OON 463, figs. 824–836): Total length 1.80. PME oval; ALE separated by more than their diameter; PLE-PME separated by less than PME radius. Endites with anterior projection relatively wide, directed laterally. Leg spination: tibiae III, IV v0-0- 1p. Embolus basally thickened, subdistally bent, producing steplike appearance; bulb elongated (figs. 832–836).

FEMALE (PBI_OON 463, figs. 837–846): Total length 2.40. PME squared; posterior eye row recurved from above, procurved from front; PLE-PME separated by PME radius to PME diameter. Leg spination: tibiae III, IV v0-0- 1p. Transverse bar at base of anterior projection very long, boat shaped; postepigastric scutum with distinct anterior and posterior margins (figs. 845, 846).

OTHER MATERIAL EXAMINED: Ecuador: Napo: Reserva Ecológica Cayambe-Coca, road from Papallacta to Oyacachi, 0u169130S, 78u059360W, Dec. 1, 2009, litter, elev. 3850 m (N. Platnick, N. Dupérre´, E. Tapia, Niarchos Exped., AMNH, MACN, QCAZ PBI _OON 425), 5 -.

DISTRIBUTION: Known only from a high elevation Polylepis forest in the Reserva Ecológica Cayambe-Coca of Napo province, Ecuador.
