- Dorsum and sides of mesosoma rugoreticulate to vermiculate; posterior surface of petiolar node mostly smooth, granulatepunctate to rugoreticulate, but lacking subparallel longitudinal rugae (

2 Small (HW =
0.90–1.17 mm
); posterior surface of petiolar node viewed from behind and above broadly fan-shaped and about as wide as long; in dorsal view, petiolar node about as wide as postpetiolar node (PW/PPW = 0.87–1.03); anterior surface of petiolar node mostly smooth and shining, forming a noticeably obtuse angle with peduncle of petiole; dorsum of postpetiole and first gastral tergum smooth and shining to partly or completely punctate, weakly shining.....................
schmitti
- Larger (HW = 1.11–1.35); posterior surface of petiolar node viewed from behind and above elongate, clearly longer than wide; in dorsal view, petiolar node notably narrower than postpetiolar node (PW/PPW = 0.78–0.90); anterior surface of petiolar node partly to completely sculptured, dull to weakly shining, forming a right to weakly obtuse angle with peduncle of petiole; dorsum of postpetiolar and first gastral tergum strongly punctate, dull.......................................
