LaPolla& S.A. Schneider(USNMENT00753609) ( NMNH); 5 paratype workerswith same locality data as holotype(specimens are from the same nest as holotype) ( NMNH& MCZC).   Worker diagnosis:Head and gaster dark brown, contrasting sharply with yellow antennae, mesosoma and legs; macrosetae on mesosoma dark brown contrasting sharply with yellow mesosoma.  Compare with:  N. semitincta  WORKER. Measurements (n=11): TL: 1.80–2.40; HW: 0.51–0.54; HL: 0.59–0.62; EL: 0.14–0.16; SL: 0.68– 0.72; WL: 0.71–0.78; GL: 0.50–0.99.

SMC: 16; PMC: 3; MMC: 15. Indices:CI: 100; REL: 36; SI: 113. Generally, as in worker with modifications expected for caste and with the following noted differences: mesosoma coloration darker brown than in worker, and with distinct yellow color along segmental margins. MALE. Measurements (n=4): TL: 2.0–2.1; HW: 0.50–0.52; HL: 0.51–0.53; EL: 0.20–0.22; SL: 0.61–0.65; WL: 0.78–0.87; GL: 0.72–0.75. SMC: 4–9; PMC: 0; MMC: 8–9. Indices:CI: 94–102; REL: 36–43; SI: 118–129.  Head: sides of head in full face view distinctly broader posterior to eyes; posterior margin rounded; clypeus evenly rounded anteriorly; mandible with 2 teeth, a long, distinct apical tooth and much smaller subapical tooth adjacent to apical tooth; basal angle sharp and distinct; Mesosoma: in lateral view, dorsal margin of mesoscutum same as height as dorsal margin of mesoscutellum; propodeum without distinct dorsal and declivitous faces. Genitalia: gonopod apex triangular but broadly rounded in lateral view; in dorsal view, gonopod margin curves away from penial sclerite; digitus with pointed apex that bends away from penial sclerite; cuspis tubular, rounded at apex bending sharply toward digitus; anteroventral process of penial sclerite coming to a point; valvura of penial sclerite placed approximately at midline (fig. 105). Color and pilosity: head and gaster dark brown, contrasting strongly with yellow mesosoma and petiole; antennae, mandibles and legs yellow to brown-yellow; mesocoxae and metacoxae often whitish-yellow; smooth and very shiny; scapes and legs with layer of pubescence; head, mesosomal notum and gastral tergites II-IV with dense pubescence.   Other material examined:  DOMINICAN REPUBLIC: Prov.  La Vega: Reserva Cientifica Ebano Verde, elev.  1070m, N 19° 01.95’, W070° 32.59’,  2 December 2003, in leaf litter, M.
