I have a question concerning Solenopsis thief ant species I hope someone can answer. I have recently collected some slightly brownish colored thief ants, a little darker than the typical bright or pale yellow. The collection was made in the South Alabama area and all were found in sparse leaf litter and soil collections.
Under the microscope they have the peduncle flange, or petiolar tooth, not sure what it is called exactly, but it is similar to the one on Solenopsis pergandei. The ones I collected are smaller than Solenopsis pergandei and are roughly the size of Solenopsis texana. The eyes are a bit larger than S. pergandei's, especially considering they are smaller specimens overall.
I have never collected Solenopsis molesta, which is what I feel they are. I think I remember someone doubting I would find them this far south, but I could be mistaken on that memory.
I will try to post some pictures of the three different species I have in my collection for comparison tomorrow.
