Identification

LaPolla et al. (2011) - Overall brown, gaster with faint dorsal bands of lighter yellowish-brown along segmental lines.

Compare with: Nylanderia luteafra

The faint dorsal bands of lighter yellowish-brown along the segmental lines of the gaster observed in N. incallida make this a fairly easy species to indentify and separates it from N. luteafra, to which it is most likely to be confused.
