Bonaldo , J.D. Dias , and D.D. Guimarães ( PBI _OON 14296, MPEG 10181 ). Female allotype from same locality ( 04°51′54″S 65°20′02″W ), S.C. Dias , D.F. Candiani , and N.F. Lo Man Hung ( PBI _OON 14297, MPEG 13809 ) . ETYMOLOGY: The specific name is a contraction of “Petroleum Goblin,” referring to the type locality, which harbors the largest petroleum production facility in Brazilian Amazonia. DIAGNOSIS: As in N. gregoblin , this species has four long carapace spikes (figs. 167–169, 190–192) and, in males, conspicuous abdominal dorsal denticles (figs. 173, 174), but differs by the absence, in both sexes, of large blunt tubercles on carapace dorsal surface (figs. 168, 191). Males are further recognized by the upright embolus, with large prolateral lamella and without prolateral prong (figs. 178–183). Females can be distinguished from those of N. termitophilus by the larger, similarly sized carapace spikes (fig. 192) and narrower epigynal atrium (fig. 197). MALE ( holotype ): Total length 2.11. Carapace dark red-brown, posterolateral surface with 2 pairs of spikes, surface of elevated portion of pars cephalica and sides smooth, lateral margin with blunt tubercles. Clypeus margin slightly rebordered, straight in frontal view. Eyes: ALE separated by less than their radius. Sternum longer than wide, orange-brown, median concavity absent, microsculpture absent, furrows shallow, anterior margin with continuous transverse Map 5.

Dorsal scutum orange-brown, surface of middle and sides smooth, anterior half with projecting denticles. Postepigastric scutum orange-brown. Legs orange-brown. Spine formula: tibia I v4-4-1, metatarsus I v2-3-0; tibia II v2-3-0, metatarsus II v2-2-0. Genitalia: sperm pore situated at level of anterior spiracles. Palp proximal segments pale orange, cymbium and bulb yellow. Embolus upright with large prolateral lamella and without prolateral prong (figs. 175–183). Figs. 175–183.

FEMALE ( allotype ): Total length 2.41. Book lung covers elliptical. Dorsal scutum anterior half without projecting denticles. Spine formula: tibia I v6-2-2, metatarsus I v3-2-1; tibia II v4-4-0, metatarsus II v3-2-0; tibia III p1-1-0, v0-1-0, metatarsus III p1-1-0, r0-1-0. Epigynal atrium narrow, with tubular median element (fig. 197). VARIATION: Some males from Huanuco and Cusco , Peru , present fewer, inconspicuous projecting denticles on the anterior half of abdominal dorsal scutum. DISTRIBUTION: Known from the Amazon Basin, from Brazilian Central Amazonia to eastern Colombia , Ecuador , and Peru (map 5).
