Niarchos bonaldoi , new species Figures 336–360

TYPES: Male holotype and female allotype from a Berlese sample of litter taken at an elevation of 1005 m in the Parque Nacional Napo-Galeras, 0u449000S, 77u289070W, Napo, Ecuador (Nov. 27, 2009; Niarchos Expedition ), deposited in QCAZ (PBI_OON 440) .

ETYMOLOGY: The specific name is a patronym in honor of Alexandre Bonaldo of the Museu Paraense Emílio Goeldi, in recognition of his enormous contributions to the organization and success of the Niarchos Expedition.

DIAGNOSIS: Males closely resemble those of N. ramirezi but have a distally thicker embolus and a less pronounced projection at the base of the embolus (figs. 344–350); females also closely resemble those of N. ramirezi but lack the median, distal invagination on the anterior receptaculum and have a shorter postepigastric scutum and thicker, less widely separated apodemes (figs. 359, 360).

MALE (PBI_OON 440, figs. 336–350): Total length 1.32. Posterior eye row recurved from above; PLE-PME separated by less than PME radius. Sternum surface smooth. Endites with anterior processes triangular, obliquely oriented. Leg spination: tibiae III, IV v0-0- 1p. Embolus narrowed at tip; distal part of bulb about half as long, half as wide as basal portion (figs. 344–350).

FEMALE (PBI_OON 440, figs. 351–360): Total length 1.32. Leg spination: tibiae III, IV v0-0- 1p. Anterior receptaculum with arched anterior margin not invaginated at middle; epigastric scutum very short; apodemes relatively wide, with relatively thick base (figs. 359, 360).
