Illustrations of two similar Dacetine ant species showing profile and full-face views of dealate queens: (A) Strumigenys subnuda (MacGown and Hill) and (B) Strumigenys margaritae Forel. Both of these minute ants (the scale bars represent 0.5mm) are slightly atypical for the genus in that they are likely semi arboreal rather than living underground or in leaf litter. Strumigenys subnuda, recently described by me and JoVonn Hill, differs from S. margaritae by the mid portion of the mesosoma (the mesopleuron) and the dorsum of the petiole and postpetiole being smooth and shiny, rather than sculptured; by having only a few erect, slightly coarse to clavate hairs present, whereas S. margaritae has numerous longer, distinctly clavate hairs present; the propodeal spines of S. subnuda are much shorter than in S. margaritae; and the first gastral tergite of S. subnuda is shiny instead of having a roughened texture as in S. margaritae.
Tremendous! Having IDed wee hymenopterans before, I know how the tiniest details can be the difference between species and I really appreciate how much effort must have gone into the placement of each seta and patch of micro-sculpture in this piece! Awesome work!
yep, you got that right! Little buggers! That, and with all the movement of exotic species around the globe these days, you pretty much have to know the worldwide fauna of the groups you work on. Crazy.
