[[ Crematogaster  HNS  (forms with deep propodeal suture) ]]

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  HNS  , stigmatica  HNS  , and unciata  HNS  were 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  HNS  . The types of chodati  HNS  were uniform red brown, and the setae on the mesosoma and fourth abdominal tergite were longer and less flattened. The types of heathi  HNS  had the coloration of goeldii  HNS  and the pilosity of chodati  HNS  . The invaginated propodeal suture is itself a variable character, grading into the condition seen in crinosa  HNS  and torosa  HNS  , and so the discussion regarding the forms with striate face applies here as well. Crematogaster goeldii  HNS  and related forms may be synonyms of other species, multiple distinct species, or one variable species.
