Figures 05, 14, 15, 20, 25 and 26E

Diagnosis (worker): Mesoscutum pale (brown to black in N. costaricana , N. minor , N. mirandula and N. batistai sp. nov.) coloration predominant yellow to yellowish-brown with yellow spots on frons and mesonotum, poorly contrasted. Anterior third of mesoscutum yellowish-brown. Apical third of metatibia with posterior half yellowishbrown. Paraocular spot not completely surrounding the antennal socket. N. rosariae sp. nov. is apparently very close to N. butteli , due the smooth and shiny integument of head, but the new species differs in the shorter body length, narrower metatibia, paraocular spot not surrounding the antennal socket, and light brown coloration in the anterior third of the mesoscutum (totally yellowish in some specimens) in relation to the dark brown of N. butelli , besides having the apical third of the terga yellowish to reddish brown.

Coloration: integument predominantly yellow to yellowish-brown. Paraocular area with the yellow spot more than 2x the diameter of the flagellum, reaching the antennal socket and the upper edge of the compound eye. Clypeus, supraclypeal area, malar area, labrum, radicle and gena yellow. Mandible yellow with apical margin reddish, condyles yellow. Scape yellow with apical half of posterior surface yellowish-brown. Pedicel dark brown. Pronotal lobe yellow. Mesoscutum yellowish-brown with yellow lateral lines. Axilla yellow. Posterior margin of scutellum yellow. Propodeum, mesepisternum and metepisternum yellow. Proleg yellow with protarsi slightly darker than the rest of the leg. Mesoleg, metacoxa, metatrochanter and metafemur yellow. Metatibia yellow with brown spot on posterior half of apical third. Metabasitarsus dark brown with yellowish-brown margins. Metatarsi yellow slightly darker than on metacoxa. Tegula yellowish-brown. Pterostigma and wing venation dark brown. T1 yellow with apical third dark brown. T2 yellowish-brown with basal third dark-brown. T3–T5 yellowish-brown. T6 and S1–S5 yellow.

Punctation: predominantly smooth and shiny; propodeum with lateral side rugose.

Pubescence: frons only with simple hairs (0.04 mm); some hairs behind genal area with curved apex (0.16 mm); lateral area of antennal socket with some hairs with two branches; simple hairs on labrum (0.15 mm) and simple setae on vertex (0.13 mm); simple hairs on coxae (0.16 mm: 0.2 mm: 0.21 mm = procoxa, mesocoxa and metacoxa, respectively); some hairs with curved apex on metacoxa; some hairs on trochanters with curved apex (0.13 mm: 0.19 mm: 0.14 mm = protrochanter, mesotrochanter and metatrochanter, respectively); femora with yellow and simple hairs on basal ventral face and with yellowish-brown short setae on apical dorsal surface (0.13/ 0.03 mm: 0.16/ 0.06 mm: 0.11/ 0.1 mm = profemur, mesofemur and metafemur, respectively); metatibia with corbicular hair (0.58 mm), almost as long as the length of scape (there are two other long hairs on corbicula: 0.53 mm and 0.32 mm, the last hair is closest to the posterior margin); posterior margin of metatibia with yellowish setae (0.22 mm); hairs of ventral surface of metatibia uniformly distributed posteriorly, leaving just a very narrow margin glabrous; basitarsi with yellowish and simple setae (0.23 mm: 0.1 mm: 0.19 mm = probasitarsus, mesobasitarsus and metabasitarsus, respectively); mesoscutum with erect setae (0.07 mm) 2.3x length of decumbent setae (0.03 mm); propodeal triangle glabrous; lateral sides of propodeum with long and simple hairs (0.13 mm, some with curved apex), short simple (0.05 mm) and branched hairs (0.05 mm); hair with more branches around the propodeal spiracle (0.09 mm); lateral area of mesepisternum with erect hairs (0.09 mm) and decumbent hairs (0.04 mm); inferior half of mesepisternum with long simple hairs (0.25 mm); metepisternum with decumbent and simple hairs or with one branch (0.04 mm); scutellum with simple hairs (0.21 mm) on dorsal surface and simple and branched setae (0.12 mm) on posterior surface; pronotal lobes with long and simple hairs (0.12 mm) and short branched hairs (0.06 mm); T1 glabrous; T2 almost completely glabrous, with more visible setae on lateral sides (0.04 mm); simple setae on T3 (0.06 mm), T4 (0.09 mm), T5 (0.08 mm) and T6 (0.09 mm: 0.15 mm = disc and lateral area, respectively); Sterna with simple hairs (0.23 mm: 0.21 mm: 0.16 mm: 0.14 mm: 0.09 mm = length of S1, S2, S3, S4 and S5, respectively).

Structures: length of compound eye 3.67x its width; inner orbits of compound eyes concave, slightly converging downward; interorbital distance shorter than length of compound eye (1.14 mm: 0.95 mm: 1.13 mm: 0.89 mm = length of compound eye and upper, median and lower interorbital distances respectively); malar area linear (0.05 mm), its length less than half width of the flagellum; clypeus length slightly less than half its width (0.38 mm: 0.83 mm = clypeal length and width, respectively), clypeus gently convex in lateral view; interalveolar distance slightly larger than diameter of antennal sockets, and much shorter than alveolorbital distance (0.19 mm: 0.24 mm: 0.15 mm = interalveolar and alveolorbital distance, and diameter of antennal socket respectively); frons slightly depressed along median line; vertex slightly convex, without postocellar carina; interocellar distance equals to the ocellorbital distance (0.19 mm); posterior margin of head slightly concave, without preoccipital carina; scape length 5,4x its width (0.54 mm: 0.1 mm); pedicel slightly larger than the ninth flagellomer (0.12 mm: 0.11 mm); anterior margin of pronotum slightly concave; scutellum paraboloid slightly projected backward; length of propodeal spiracle 4.6x its width (measured from the inner margin); metatibia subtriangular with posterior distal margin slightly angulated; length of hind tibia 2.5x its width (1.3 mm: 0.52 mm); metabasitarsus 2x longer than broad (0.67 mm: 0.33 mm) with posterior angle projected downward, overcoming the encounter line with the following tarsus; vein separating first and second submarginal cells (Rs) and separating second and third (2 nd rs-m) virtually absent.
