Niarchos facundoi , new species Figures 656–678

TYPE: Male holotype taken at an elevation of 3400 m at Shoupshe , Yumate, Molleturo, 2.76961uS, 79.42543uW, Azuay, Ecuador (Jan. 20, 2010; E. Tapia), deposited in QCAZ (PBI_OON 446) .

ETYMOLOGY: The specific name is a patronym in honor of Facundo Labarque, in recognition of his many contributions to the success of the Niarchos Expedition.

DIAGNOSIS: Males resemble those of N. palenque but have a much longer translucent tip on the embolus (figs. 664–668); females have a distinctive, oval sclerotization between the epigastric and postepigastric scuta (figs. 677, 678).

MALE (PBI_OON 446, figs. 656–668): Total length 1.83. Posterior eye row straight from above; PLE-PME separated by PME radius to PME diameter. Sternum surface finely reticulate. Endites with anterior processes narrow, very long, with tip directed laterally. Leg spination: tibiae: III v0-0-1p; IV v0-0-2; metatarsi III, IV v0-0-2. Embolus relatively long, distal portion translucent (figs. 664–668).

FEMALE (PBI_OON 448, figs. 669–678): Total length 1.83. Posterior eye row recurved from above. Leg spination: tibiae III, IV v0- 0- 1p. Area between epigastric and postepigastric scuta occupied by wide, oval sclerotization (figs. 677, 678).

DISTRIBUTION: Known only from Azuay province, Ecuador.

UNPLACED SPECIES

The three species described below are known only from females; based on their unusual genitalic morphology, we suspect that they represent at least one additional species group for which no males are currently known.
