Figures 7, 13, 22, 26, 33, 34, 38, 42, 218–241; map 5

TYPE: Male holotype from Campo de Provas Brigadeiro Velloso ( Serra do Cachimbo , 09°21′39″S 55°02′01″W), Novo Progresso, Pará, Brazil, 07–17 Sep. 2003, A.B. Bonaldo, D.R. Santos-Souza and D.D. Guimarães ( PBI OON 14295 View Materials , MPEG 13671 View Materials ) GoogleMaps   .

ETYMOLOGY: The specific name refers to the Boi-Bumbá folkloric festival, which takes place annually in north and northeastern Brazil and is especially appreciated in the state of Pará.

DIAGNOSIS: Males differ from those of other species without developed carapace spikes by the combination of smooth carapace (figs. 219, 222), well-developed denticles on the anterior end of dorsal scutum (figs. 224, 226) and rounded embolus (figs. 228, 231), not elongated as in N. barreirosi   . The shorter pedicel, inserted in parallel to postepigastric scutum (fig. 224), further separates this species from N. hispidus   .

MALE (holotype): Total length 1.88. Carapace orange-brown, posterolateral surface without spikes, with a pair of large blunt tubercles near the posterior margin, surface of elevated portion of pars cephalica and sides smooth, lateral margins with small, inconspicuous 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, microsculpture absent, furrows shallow, inconspicuous, anterior margin unmodified; setae evenly scattered, originating from small tubercles. Chelicerae, endites, and labium orange-brown. Book lung covers large, ovoid. Pedicel tube long. Dorsal scutum orange-brown, surface of middle and sides smooth, anterior half with projecting denticles. Postepigastric scutum orange-brown. Legs pale orange. Spine formula: tibia I v2-4-0, metatarsus I v2-3-0. Tarsi I to IV superior claws tooth not examined in detail. Genitalia: epigastric region with sperm pore small, narrow, slitlike, situated between anterior and posterior spiracles. Palp proximal segments pale orange, cymbium and bulb yellow. Embolus rounded, without prolateral prong or prolateral lamella (figs. 227–235).

FEMALE: Unknown.

DISTRIBUTION: Known from the type locality, Serra do Cachimbo , State of Pará, Brazil (map 5)   .
