The distinctive feature of these forms is a deeply invaginated propodeal suture and an elevated and compressed dorsal face of propodeum. From my cursory examination, goeldii, stigmatica, and unciatawere very similar. They were bicolored, with red brown head and mesosoma and contrasting black gaster. The anteroventral petiolar tooth was moderately well developed and the pilosity was much like torosa. The types of chodatiwere uniform red brown, and the setae on the mesosoma and fourth abdominal tergite were longer and less flattened. The types of heathihad the coloration of goeldiiand the pilosity of chodati. The invaginated propodeal suture is itself a variable character, grading into the condition seen in crinosaand torosa, and so the discussion regarding the forms with striate face applies here as well. Crematogaster goeldiiand related forms may be synonyms of other species, multiple distinct species, or one variable species.
