Stigmacros

Stigmacros aemula, copyright Will Ericson/antweb.org.


Belongs within: Melophorini.

Stigmacros is an Australian genus of small, generalist predatory ants found in leaf litter or arboreally. The genus has been divided into subgenera based on spination of the propodeum and petiole, and distinctiveness of the mesonotum, but the significance of these features requires re-evaluation (Heterick 2009).

Characters (from Heterick 2009): Antenna with 10 segments; palps long (palpal formula 6, 4); propodeum with one or more pairs of spines, teeth or protuberances, often including pair over propodeal spiracle; petiolar node often with pair of spines or lateral processes.
