Aphaenogaster huachucana is a rarely collected ant species described from the Huachuca Mountains of Arizona. The sexual forms (males and females) were described for the first time in 1951. Two subspecies are recognized: A. h. huachucana and A. h. crinimera. The species belongs to the spine-waisted ant genus Aphaenogaster, which includes frequent hosts for myrmecophilous beetles in the southwestern United States.
Aphaenogaster tennesseensis
Tennessee Collared Ant, Tennessee Spine-waisted Ant
Aphaenogaster tennesseensis is a medium-sized ant species in the family Formicidae, commonly known as the Tennessee Collared Ant or Tennessee Spine-waisted Ant. It belongs to the genus Aphaenogaster, a diverse group of ants found primarily in temperate and subtropical regions. The species has been documented in the eastern United States, with records from Vermont and other states. Workers have been observed foraging on fungi and scavenging dead or injured insects.
Aphaenogaster texana
Texas Collared Ant
Aphaenogaster texana is a species of ant in the family Formicidae, commonly known as the Texas Collared Ant. It belongs to the genus Aphaenogaster, a diverse group of ants often referred to as spine-waisted ants due to their distinctive petiole structure. The species was described by Wheeler in 1906 and includes two recognized subspecies: A. t. texana and A. t. carolinensis.
Aphaenogaster umphreyi
Aphaenogaster umphreyi is a rarely collected ant species in the genus Aphaenogaster, described in 1998 from Florida. The species belongs to a genus predominantly consisting of ground-nesting species in eastern temperate forests. Like its congener A. mariae, it may exhibit arboreal nesting habits, though this has not been confirmed. The species remains poorly known due to limited collection records.
