Octostruma petiolata

Identification
This species is known from southern Brazil. Workers can be identified by the combination of strongly transverse petiolar node in dorsal view, mesosoma lacking erect setae, large size (HW 0.85–0.90), and strong laminar transverse carina joining the propodeal spines. I examined a worker from Itajubá, Santa Catarina State (MCZ). (Longino 2013)
