Pale-yellow with REL: 19–23 and SI2: 15–19.
Compare with: Nylanderia guatemalensis.
Workers of Nylanderia lucayana and N. guatemalensis are very similar but can be best separated another using eye size. The eye of N. lucayana is generally smaller and it has a relative eye index 19–23. In N. guatemalensis, the relative eye index is above 21, with most specimens in the mid-20s and some approaching 30. The SI2 index also effectively separates the two species (measured range in N. lucayana: 15–19; measured range in N. guatemalensis: 18–26). There is also a color difference between the two but it is difficult to appreciate it until one has looked at many specimens of N. guatemalensis. Nyladeria guatemalensis is never as pale yellow as seen in N. lucayana. Finally, N. lucayana is putatively an endemic to the Lucayan Archipelago so it is likely only in this area that separating N. guatemalensis and N. lucayana is necessary. Gotzek et al. (2012) clearly show this species (listed as Nylanderia n.sp. 83) to be quite distinct phylogenetically from N. guatemalensis (Gotzek et al. 2012 and unpublished data).
