TYPES: Male holotype from Estação Cientifica Ferreira Penna, FLONA Caxiuana, Melgaço , Brazil (01°44′15.5″S 51°26′42.0″W), 25 Oct 2003, J.A.P. Barreiros ( PBI _OON 14441, MPEG 10369 ). Female allotype same locality and collector, 16 Oct 2003 ( PBI _OON 14442, MPEG 10383 ) .

ETYMOLOGY: The specific name is a patronym in memory of the collector of the holotype, José Augusto Pereira Barreiros, who dedicated his brief life to the study of soil spiders and was an enthusiast of the goblin spiders.

DIAGNOSIS: Males resemble N. hispidus and N. boibumba by the smooth carapace surface, without developed posterior spikes (figs. 243, 246), but differ by the long and slender embolus, with pointed apical projection (figs. 43, 253, 259), and by the absence of abdominal anterior denticles (fig. 250, 251). Females resemble those of N. termitophilus , N. hispidus , N. furtivus , and N. keyserlingi by the wide epigynal atrium, differing by the unique combination of the posteriorly positioned median element (fig. 274) and absence of carapace spikes (fig. 268).

MALE (holotype): Total length 1.49. Carapace orange-brown, posterolateral surface without spikes, surface of elevated portion of pars cephalica and sides smooth, lateral margin with blunt tubercles. Clypeus margin unmodified, straight in frontal view. Eyes: ALE separated by less than their radius. Sternum as long as wide, orange-brown, median concavity absent, with a Map 6.

median field of small pits, furrows deep, narrow, anterior margin unmodified, setae evenly scattered, originating from small tubercles. Book lung covers large, ovoid. Pedicel tube medium sized. Dorsal scutum orange-brown, middle and sides surface smooth, anterior half without projecting denticles. Postepigastric scutum orange-brown. Legs pale orange. Spine formula: tibia I v4-4-0, metatarsus I v2-2-1. Genitalia: sperm pore situated at level of anterior spiracles. Palp proximal segments, cymbium, and bulb yellow. Embolus long and slender, with pointed apical projection, without prolateral prong or prolateral lamella (figs. 252–260).
