SUBFAMILY FORMICINAE View in CoL View at ENA   HNS LEPELETIER

Workers and queens with ventral apex of gaster (hypopygium) produced into a conical structure terminating in a circular acidopore fringed with hairs. Petiole a large scale or distinct node. Gaster with 5 distinct tergites visible in dorsal view. Males have semi-erect hairs on dorsum of alitrunk.
