Niarchos foreroi , new species Figures 476–560

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 450) .

ETYMOLOGY: The specific name is a patronym in honor of Dimitri Forero, in recognition of his many helpful contributions to the Niarchos expedition.

DIAGNOSIS: Males can easily be recognized by the sinuous and distally narrowed embolus (figs. 484–488), females by the long, narrow anterior genitalic process (figs. 559, 560).

MALE (PBI_OON 450, figs. 476–519): Total length 1.83. Posterior eye row straight from above. Sternum surface smooth. Endites with anterior projections distally situat- ed, small, at apex of longitudinal ridge. Leg spination: tibiae IV v0-0- 1p. Embolus darkened, narrowed at tip, accompanied by membranous element (figs. 484–488, 515– 519).

FEMALE (PBI_OON 450, figs. 520–560): Total length 1.94. Leg spination: tibiae: III v0-0-1p; IV v0-0-2; metatarsi: III v0-0-1p; IV v0-0-2. Anterior genitalic projection straight, narrow, not distally expanded (figs. 559, 560).

OTHER MATERIAL EXAMINED: Five males and eight females taken with the types (AMNH, MACN, QCAZ PBI_OON 40824).

DISTRIBUTION: Known only from Loja province, Ecuador.
