Ant? - Acanthostichus

Ant? - Acanthostichus
Picture Rocks, NW of Tucson, Pima County, Arizona, USA
June 7, 2011
Size: 3 mm

Moved from Cerapachyinae.


Could be a cerapachyine ant
Three species in two genera of this subfamily occur in Arizona. Are any other views available?

Sorry, no
other views. Thank you both for your help. Maybe I'll find another one, it was at my home black light

I concur with James: This is a cerapachyine. A caveat is that male cerapachyines are most easily separated at the genus-level via characters visible in profile view. That being said, I would call this an Acanthostichus given the wing venation. From the cerapachyine male material I have been able to examine Acanthostichus may be separated from the Cerapachys augustae group by the closed 1st or compound 1st + 2nd submarginal cells, which is indeed the case for the imaged specimen. The ideal additional shot, if one is available, would again be in profile view. Good find!



I'm not quite sure
side views really help to see key features on ants...
