Aphaenogaster texana

Nests under stones, in moist, rocky soil.

Identification
Aphaenogaster texana was described as similar to Aphaenogaster carolinensis, but with longer spines and directed further upwards. This research finds overlapping morphological characters with both Aphaenogaster texana and Aphaenogaster rudis. DNA data indicates that A. texana occurs west of the Mississippi River.
