Niarchos keili , new species Figures 121–133

TYPE: Male holotype from Berlese sample of rain forest litter taken at an elevation of 1700 ft at a site 4 km E of Santo Domingo, Santo Domingo de Los Tsáchilas, Ecuador (June 22, 1975; S. Peck), deposited in FMNH (PBI_OON 10534) .

ETYMOLOGY: The specific name is a patronym in honor of Clifford Keil, Director of the Museum of Invertebrates at the Pontificia Universidad Católica del Ecuador, in recognition of his vital collaboration in the planning and execution of the Niarchos Expedition.

DIAGNOSIS: Males can easily be recognized by the distinct anterior projections on the chelicerae (fig. 126), the rounded protrusions just behind the anterior process on the endites (fig. 128), and the basally narrowed embolar region (figs. 129–133).

MALE (PBI_OON 10534, figs. 121–133): Total length 1.58. Posterior eye row straight from above; PLE-PME separated by PME radius to PME diameter. Sternum surface finely reticulate. Endites with posterior directed process shaped like duck’s beak, followed posteriorly by rounded protuberance (fig. 128). Leg spination: tibiae III, IV v0-0- 1p. Embolar region basally narrowed, distally expanded, preceded by dorsal protrusion; bulb with strong basal projection on retroventral side (figs. 129–133).

FEMALE: Unknown.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Western slopes of the Andes, in the Santo Domingo region of central Ecuador.
