Aphaenogaster punctaticeps

This ant nests in kangaroo rat mounds (Cover, pers. commun.) or in prairie dog towns (Fagerlund, pers. comun.). It apparently steals seeds from the rodents. (Mackay and Mackay 2002)

Identification
The head of this species is elongate (head width /head length 0.71), and nearly completely covered with punctures. Most of the mesosoma has similar sculpture. The propodeal spines are small. This species is similar to Aphaenogaster texana but differs in that the posterior border of the head is moderately pointed (rounded in A. texana) and the dorsum of the head is primarily punctate (rugose with punctures in the intrarugal spaces in A. texana). (Mackay and Mackay 2002)
