TYPES: Male holotype and female paratype taken from litter along stream trail at an elevation of 2130 m at the Yanayacu Biological Station , 0u 35.9559S, 77u 53.4319W, Napo, Ecuador (Nov. 25, 2009; Niarchos Exped. ), deposited in QCAZ (PBI_OON 409) GoogleMaps .

ETYMOLOGY: The specific name is Latin, meaning ‘‘armed with a shield,’’ referring to the dorsal abdominal scutum found in males (but not females).

DIAGNOSIS: Males resemble those of N. ramirezi and its relatives, but have a thicker embolar base (figs. 234–238); females resemble those of N. ramirezi and N. bonaldoi in having a thumblike anterior process on the anterior receptaculum, but have a thick transverse sclerite connecting distally narrower apodemes (figs. 310, 311).

MALE (PBI_OON 407, figs. 226–272): Total length 1.41. Posterior eye row straight from above. Sternum surface smooth. Endites with anterior projection triangular, laterally directed. Leg spination: tibiae IV v0-0-2. Embolus on wide base about half as long as rest of bulb, tip bent at right angle (figs. 234–238).

FEMALE (PBI_OON 407, figs. 273–311): Total length 1.76. Leg spination: tibiae IV v0- 0-2. Epigastric scutum with posterior margin only slightly invaginated at middle, postepigastric scutum short, occupying only about half of space between epigastric furrow and posterior spiracles (figs. 310, 311).
