Crematogaster nitidiceps  and Crematogaster victima  occur in local sympatry across eastern Paraguay. There is no reason to consider the two forms conspecific, and indeed the two forms are likely not even close relatives. I have not examined type material of either form, but Jack Longino has confirmed the identification of both species in my Paraguayan material and concurs with a change in status for C. nitidiceps  (Longino, pers. comm.). In Paraguay, the two species differ in a number of characters, including: antennal scapes in repose fail to meet posterior cephalic margin in C. nitidiceps  but surpass posterior margin in C. victima  ; head in full-face view longer than broad in C. niticeps  but broader than long in C. victima  ; sculpture of lateral face of pronotum smooth and shining in C. nitidiceps  but punctate in C. victima  ; dorsum of head bearing only one or two pairs of standing setae in C. niticeps  but bearing> 20 standing clavate setae in C. victima  . The two forms show additional differences in eye size, petiolar structure, and mesosomal structure.
