I cannot distinguish this species from torosa on morphological grounds. It appears to be the only crinosa complex species on Jamaica, and it is very abundant there. The workers build large, completely exposed carton nests that wrap around relatively narrow gauge stems on small trees. This nesting behavior is unique and highly distinctive within the crinosa complex. All other crinosa complex nests I have seen have been in dead wood, with at most small carton baffles around nest entrances and forming partitions inside the nest. Thus the population has been on Jamaica long enough to evolve this distinctive nesting behavior (or retained a primitive nesting behavior that has been lost everywhere else).
