TYPE: Male holotype from Berlese sample of forest litter taken at an elevation of 700 ft at the Río Palenque Station, 47 km S of Santo Domingo, Los Ríos, Ecuador (June 18–30, 1975; S., J. Peck), deposited in FMNH (PBI_OON 37749) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males resemble those of N. facundoi but have a much shorter translucent tip on the embolus (figs. 568–572); females lack the ovoid sclerotization between the epigastric and postepigastric scuta found in those of N. facundoi , and have a shorter, anteriorly wider anterior genitalic process (figs. 654, 655).

MALE (PBI_OON 37749, figs. 561–611): Total length 1.17. Posterior eye row pro- curved from above; PLE-PME separated by less than PME radius. Sternum surface smooth. Endites with anteromedian projections narrow, distally situated, directed ventrally. Leg spination: tibiae IV v0-0-2. Embolus relatively short, distal portion translucent (figs. 568–572).

FEMALE (PBI_OON 37830, figs. 612– 655): Total length 1.41. Leg spination: tibiae IV v0-0-2. Internal genitalic sclerotizations visible externally in weakly sclerotized area between epigastric and postepigastric scutum (figs. 654, 655).
