is distributed from southeastern United States (Florida), the Caribbean and Mexico, south to Argentina.
In the Caribbean region, colonies of P. cubaensis
occupy dead stems of various woody and herbaceous plants (Ward, 1985), often in littoral environments. Mainland populations come from a variety of habitats, including tropical dry forest, savannah, roadside verge, second-growth lowland rain forest, rain forest edge and montane rain forest edge. Nesting habits of these mainland populations are probably also generalized, but unfortunately most records consist of foraging workers rather than nest series.
Among members of the oculatus
group (see Ward, 1989), workers of cubaensis
can be recognized by the following combination of features:
- medium size (HW 0.65-0.78)
- punctate-sublucid head; at least some punctures separated by half their diameters or more, especially between the ocelli and compound eye, and immediately posterior to compound eye
- relatively short eyes (REL2 0.65-0.76)
- moderately broad fore femur (FI 0.41-0.50)
- petiole with rounded dorsolateral margination
can be diagnosed minimally by the combination of medium size (HW 0.65-0.78); a punctate-sublucid head; relatively short eyes (REL2 0.65-0.76); moderately broad fore femur (FI 0.41-0.50); and petiole with rounded dorsolateral margination. The largest workers of P. cubaensis
from South America overlap in size with the smallest workers of P. curacaensis
; they are distinguished from the latter by the possession of a broader fore femur, longer head, flatter occipital margin, shorter funicular segments, and gentler dorsolateral margination of the petiole. At the lower limits of its size range, P. cubaensis can be difficult to distinguish from P. urbanus. Workers of the latter have broader fore femora and longer eyes for a given head width, compared to P. cubaensis (see scatter plots in Ward, 1989). Workers of P. cubaensis differ from those of P. elongatus by their larger average size, shorter eyes and lower petiole height in the region of size overlap, and sublucid head and mesosoma.
