Niarchos baehrae , new species Figures 134–143

TYPE: Female holotype taken by hand collecting from forest litter at an elevation of 1625 m at Otonga, 0u259110S, 78u599410W, Cotopaxi, Ecuador (Dec. 8, 2009, B. Baehr, Niarchos Exped. ), deposited in QCAZ (PBI_OON 429).

ETYMOLOGY: The specific name is a patronym in honor of Barbara Baehr, collector of the holotype and many other fascinating oonopids and a participant in the Niarchos Expedition.

DIAGNOSIS: Females can easily be recognized by the triangular epigynal atrium (fig. 141) and the presence of both anterior and posterior apodemes, as well as tubular pockets within the anterior receptaculum (figs. 142, 143). The large size difference makes it unlikely that this could be the female of N. keili .

MALE: Unknown.

FEMALE (PBI_OON 429, figs. 134–143): Total length 2.37. Posterior eye row recurved from above; PLE-PME separated by PME radius to PME diameter. Sternum surface finely reticulate. Leg spination: tibiae III, IV v0-0-1p; metatarsi IV v0-0-2. Genitalia with distinct atrium (figs. 142, 143).

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Known only from the vicinity of the Bosque Integral Otonga on the western slope of the Ecuadorean Andes.
