Pheidole drepanon

The type colony was collected in tropical evergreen forest. (Wilson 2003)

Identification
See the description in the nomenclature section.

Distribution
Pheidole drepanon is evidently an endemic of the Dominican Republic; a second collection was made by P. S. Ward 22 km north of Pedernales, 18°09’N, 71°35’W, 1600 m. P. drepanon might also occur in Haiti, especially since the type locality is close to the border. (Wilson 2003)

This taxon was described from Dominican Republic.
