Not sure about pronotal, but clearly has propodeal teeth, diagnostic for this species. After reviewing, and consulting with colleagues, it appears this is in fact the recently arrived G. trianularis. This is a Neotropical millipede hunter, first reported from Florida about 10 years ago, now apparently in the whole Gulf Coast region. It is larger (5 vs. 4mm), darker in color and has slightly coarser longitudinal grooves than G. hartmanni.

This is from the same colony of ants
I just took the image a while later.

 
Gnamptogenys triangularis is
Gnamptogenys triangularis is a new record for Texas and a short note on this would be appropriate. Also, it would be nice to have some specimens deposited in a museum.
