Niarchos grismadoi , new species Figures 679–688

TYPE: Female holotype taken by hand collecting from forest litter at an elevation of 855 m at Otongachi , 0u199150S, 78u579060W, Santo Domingo de Los Tsáchilas, Ecuador (Dec. 6, 2009; B. Baehr, Niarchos Exped. ), deposited in QCAZ (PBI_OON 406) .

ETYMOLOGY: The specific name is a patronym in honor of Cristian Grismado, in recognition of his many contributions to the success of the Niarchos Expedition and especially his dedicated sorting of the bulk collections resulting from that fieldwork.

DIAGNOSIS: Females closely resemble those of N. matiasi in having an enlarged but membranous anterior receptaculum that occupies most of the distance between the epigastric furrow and pedicel, but the anterior sclerotization on that receptaculum is much smaller (figs. 687, 688).

MALE: Unknown.

FEMALE (PBI_OON 406, figs. 679–688): Total length 1.57. Posterior eye row straight from above; PLE-PME separated by PME radius to PME diameter. Sternum surface smooth. Leg spination: tibiae: III v0-0-1p; IV v0-1p-2; metatarsi IV v0-0- 1p. Anterior receptaculum enlarged, membranous, with small anterior sclerotization (figs. 687, 688).

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Known only from the type locality in Santo Domingo de Los Tsáchilas province, Ecuador.
