/. hispaniolae was also compared with series belonging to 39 Old 
World Iridomyrmex species, including all of the principal species 
groups. It bears an overall resemblance to certain of them, especially 
anceps, emeryi, and pallidus, but differs substantially in various 
combinations of details in the petiole shape, pilosity, eye size, and 
sculpturing. 
Iridomyrmex humiloides, new species 
(Fig. 11) 
Diagnosis {worker). A relatively small species resembling /. 
humilis of South America. With this living form it differs from other 
members of the species, including despertitus and pruinosus, most 
conspicuously in the concave anterior border of its clypeus. It differs 
from humilis (and other contemporary similar species) by the fact 
that its eyes exceed the lateral borders of the head in full-face view, 
whereas in the living species the outer margins of the eyes do not 
reach the lateral borders of the head.
