Diagnosis. The worker of this species can be recognized by the combination of the following features: mesoscutum and mesoscutellum densely and coarsely foveate; antennal scape with short erect setae, at most 0.5 times the diameter of scape; ocellocular area, between lateral ocellus and inner margin of compound eye, with contiguous punctures similar to those on frons; posterior margin of mesoscutellum with deep and semicircular emargination, about 1.8 times broader than long; and wing membrane, veins and pterostigma light reddish brown contrasting with wing apex dark grayish brown. This species is most similar to N. perilampoides sharing an antennal scape with short setae and punctation of the ocellocular area. However, in N. camargoi the emargination on the posterior margin of mesoscutellum is deeper and the wing membranes, veins and pterostigma are light reddish brown contrasting with wing apex dark grayish brown. In N. perilampoides the emargination on the posterior margin of mesoscutellum is 3.8 times broader than long and the wing membrane, vein, and pterostigma are brownish.
Description. Worker: Total body length 4.5 mm; head width 1.84 mm; maximum width of mesoscutum 1.39 mm; forewing length (including tegula) 4.7 mm. Head 1.2 times wider than long; malar area about 0.7 times width of F3; clypeus about 1.8 times broader than long; intertorular distance 1.3 times torular diameter; torulorbital distance 1.7 times torular diameter; interocellar distance 2.5 times OD, 1.2 times longer than ocellocular distance; ocelloccipital distance about twice as long as OD; scape 5.5 times longer than wide, 0.8 times width of F3; pedicel about as long as broad, shorter than first flagellomere; flagellomeres broader than long, except apical flagellomere longer than broad. Mesoscutellum 1.3 times broader than long, basal fovea V-shaped, about as long as broad, posterior margin with median emargination large, semicircular, about 1.8 times broader than long, tooth lateral to emargination acute.
Color black, except as follows: dark reddish brown on apical two-thirds of mandible; light brown on antennal scape and labrum; bright yellow on lateral margin of mesoscutum, axilla, lateral tooth of posterior margin of mesoscutellum, outer surfaces of pro- and mesotibiae basally, posterior margin of metatibia, except apically; yellowish on antennal flagellum, distitarsi, and anterior and posterior margins of metabasitarsus. Wing membrane, veins and pterostigma light reddish brown contrasting with wing apex dark grayish brown, including apical portion of Rs.
Pubescence light reddish brown, except minutely branched, appressed setae on head and mesosoma whitish. Antennal scape with simple, short (at most half diameter of scape) setae along its inner margin. Mesoscutum with setae as long as those on vertex (1.0× OD); mesoscutum with setae about twice as long as those on mesoscutum (2.0× OD); pro- and mesotibiae with setae about as long as median ocellus diameter.
Clypeus and supraclypeal area with minute, shallow punctures; frons with contigous, coarse punctures as on ocellocular area. Mesoscutum and mesoscutellum foveate, fovea large (0.5–1.0 times OD).
Male. Unknown.

Etymology. The specific epithet is a patronym honoring the late J.M.F. Camargo (1941–2009), distinguished bee specialist, who first recognized the novelty of this species.
Comments. The fovea of the basal area of propodeum are larger in the paratypes from Pichincha and Esmeraldas than in those from Loja.
Distribution. Ecuador (Cotopaxi, Esmeraldas, Loja, Pichincha).
