Measurements (n=5) : TL: 1.94–2.53; HW: 0.45–0.56; HL: 0.55–0.63; EL: 0.14–0.15; SL: 0.63– 0.74; WL: 0.61–0.75; GL: 0.78–1.20. SMC: 19–27; PMC: 3–4; MMC: 2. Indices: CI: 83–88; REL: 22–26; SI: 112–148; SI2: 19–24. Head : sides of head in full face view slightly rounded; posterolateral corners rounded or angled; posterior margin slightly rounded; anterior clypeal margin convex; three ocelli present; eye well-developed. Mesosoma : in lateral view, pronotum convex; anterior margin of mesonotum more or less even with posterior pronotal margin; metanotal area without short flat area before spiracle; dorsal face of propodeum slightly convex to nearly flat; dorsal face of propodeum lower than mesonotum in lateral view. Color and pilosity : dark brown, with antennae and legs, especially (except procoxae which are dark brown) lighter yellowish-brown; funiculi and legs become more yellowish distally (typically mesocoxa, metacoxa and trochanters are lighter than femora and tibiae); pubescence sparse to absent except for abundant pubescence on mesonotum and gaster; dorsal face of propodeum with fringe of pubescence.

Etymology: Species epithet, sierra , is Spanish for mountains or mountain range, in reference to the habitats in which this species holotype specimen was collected. Notes: Workers of this species are some of the smallest found in Cuba . The abundant pubescence on the mesonotum and gastral tergites make it fairly easy to separate workers of this species from those of N. xestonota , which is a Cuban species similar in size but it completely lacks pubescence on the mesonotum and gastral tergites.
