xi. Crematogaster tetracantha- group

1. Pronotum antero-laterally with distinct sharp margins or denticles ( Fig. 38 ) or spinose protuberances ( Fig. 39 ). 2. Petiole in dorsal view either greatly flared ( Fig. 17 a) and transversely convex, or suboval ( Fig. 18 a).

This group comprises all members of the previous subgenus Xiphocrema and some additional species from Crematogaster , and thus to date has the following members: C. dahlii Forel , C. tetracantha Emery , C. recurva Emery , C. elegans Smith , C. flavitarsis Emery , C. weberi Emery , C. elysii Mann , C. abrupta Mann and C. tarsata Smith.
