Niarchos loja , new species Figures 453–475

TYPES: Male holotype and female allotype taken under mossy stones at an elevation of 2100 m at Celica , 4.09896uS, 79.97994uW, Loja, Ecuador (Feb. 25, 2010; E. Tapia), deposited in QCAZ (PBI_OON 449) .

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

DIAGNOSIS: Males can easily be recognized by the deeply bifid embolus accompanied by a long, basal process (figs. 461–465), females by the heavily sclerotized, Y-shaped anterior genitalic process (figs. 474, 475).

MALE (PBI_OON 449, figs. 453–465): Total length 1.72. Posterior eye row straight from above; PLE-PME separated by PME radius to PME diameter. Sternum surface finely reticulate. Endites with anterior projections distally situated, small, at apex of longitudinal ridge. Leg spination: tibiae: III v0-0-1p; IV v0- 0-2. Embolus darkened, narrowed at tip, accompanied for full length by long, dark, narrow, basal projection (figs. 461–465).

FEMALE (PBI_OON 449, figs. 466–475): Total length 2.22. Leg spination as in male. Anterior genitalic process heavily sclerotized, Y-shaped (figs. 474, 475).

OTHER MATERIAL EXAMINED: One male and one female taken with the types (AMNH PBI_OON 4082), and one female from Peru: Cajamarca: San Ignacio, Santuario Nacional Tabaconas-Namballe, Oct. 2007 (S. Castro, MELM PBI_OON 15054).
