LaPolla et al. (2011) - Overall dark brown with rugulose head and mesosoma; SL ≥ 0.9 mm.
Compare with: Nylanderia lepida
This species has one of the longest scapes of any African Nylanderia. It is most likely to be confused with N. lepida, but N. lepida is generally smaller in overall size and its cuticle is typically very smooth and shining.

- impolita. Nylanderia impolita LaPolla & Fisher, in LaPolla, Hawkes & Fisher, 2011: 16, figs. 10-12, 76 (w.) GABON.
Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
Measurements (n = 6): TL: 2.6–3.1; HW: 0.59–0.74; HL: 0.7–0.8; EL: 0.17–0.18; SL: 0.91–0.98; PW: 0.4–0.48; WL: 1.0–1.05; GL: 0.9–1.4
Indices: CI: 83–93; REL: 21–24; SI: 131–161
Overall the worker of N. impolita matches the description of Nylanderia lepida with the following differences: 1) larger overall size (TL: 2.6–3.1); 2) scape length ? 0.9 mm; 3) head and mesosoma rugulose; 4) mesopleuron with distinct rugulae; 5) mesosoma more elongated with lower pronotum than in N. lepida (WL ≥ 1.0 mm); 6) generally with more erect macrosetae present on the scapes (SMC > 20, often exceeding 30).
Holotype worker, GABON: Prov. Ogoové-Maritime: Réserve des Monts Doudou, 24.3 km 307° NW Doussala, 2°13.35’ S, 10°24.35’ E, elev. 350 m; malaise trap, coastal lowland rainforest, forest margin along river; 9–10.iii.2000 (S. van Noort) (California Academy of Sciences) (CASENT0179589); 1 paratype worker, same label data as holotype; 1 paratype worker with same label data as holotype except date: 8.iii.2000; 1 paratype worker with same label data as holotype except date: 6–7.iii.2000 (CASC, National Museum of Natural History)
The specific epithet impolita (L. = unpolished) is in reference to the fact this species possesses a rugulose cuticle on the head and mesosoma.
