Nylanderia scintilla

Identification
LaPolla et al. (2011) - Head width less than 0.51 mm; brownish-yellow species, with very short, angular propodeal dorsal face; all coxae the same color.

Compare with: Nylanderia boltoni and Nylanderia umbella

This species is most likely to be confused with N. boltoni, however there are several diagnostic morphological features that can be used to separate the two species. In N. scintilla the coxae are all the same color (not with lighter meso/metacoxae), and the head is more quadrate than in ''N. boltoni. Nylanderia boltoni, N. scintilla, and N. umbella'' appear to be closely related based on overall worker morphology.

Overall brownish-yellow, often with slightly darker head and gaster, and always with distinctly lighter antennae and legs; coxae all the same color; cuticle smooth and shining. Head with dense layer of short pubescence; scapes surpass posterior margin by about length of first 2–3 funicular segments; scapes with scattered erect macrosetae (SMC = 13–20); head roughly quadrate in appearance with more angular-shaped posterolateral cornors present; posterior margin slightly emarginate medially. Mesosoma with macrosetae of varying lengths on pronotum (PMC = 2–5; MMC = 2); pubescence sparse with small patches on dorsum of mesonotum and propodeum; metanotal area compact; dorsal face of propodeum short and angular, slightly lower than mesonotum; declivitous face distinctly longer than dorsal face. Gaster with scattered erect macrosetae and dense layer of short pubescence giving gaster a somewhat silky appearance.

Type Material
Holotype worker, IVORY COAST: Palmeraie Lame, no. 86, 13.ii.1976 (T. Diomande) (BMNH); 9 paratype workers same label data as holotype; 3 paratype workers, IVORY COAST: Palmeraie Lame, no. 87; 5.iii.1976 (T. Diomande).

Etymology
The specific epithet scintilla (L. = spark) is in reference to the yellow color, shiny pubescence and small size of this species.
