Stenamma lobinodus

This species is known only from Winkler or Berlese extractions of sifted leaf litter taken from montane, mesophyll forests. Nests have never been collected. It is likely a mid-elevation specialist given its occurrence between 860 to 1620 m.

At the El Cielo reserve in northern Mexico, Branstetter (2013) found a lone worker that looked like S. lobinodus foraging on a mud/clay bank bordering the main road (specimen viewed with a hand lens). Unfortunately the worker escaped and no nest was located. The presence of the worker on a mud bank suggests that S. lobinodus may nest in banks like the similar-looking Stenamma diversum. Both species have almost the same sculpture, color and propodeal spines.
