A subgeneric revision of Crematogaster and discussion of regional species-groups (Hymenoptera: Formicidae) Author Blaimer, Bonnie B. text Zootaxa 2012 3482 47 67 journal article 10.5281/zenodo.209409 b98d4ae1-2d1a-4707-848d-1f4841755f22 1175-5326 209409 42F5ABE3-37EC-48D6-AB1A-357BCC93DF68 iv. Crematogaster kneri- group 1. Petiole moderately to sharply flared, or suboval ( Figs 14 a, 16a) 2. Postpetiole globular, with at most weak posterior impression ( Figs 24, 25 ). 3. Pronotum often with angular or tuberculate lateral margins ( Fig. 30 ). 4. Mesonotum often postero-laterally angulate or denticulate ( Fig. 31 ). This group will probably contain a large part of the former subgenus Sphaerocrema , but this remains to be tested. At the moment the following species are assigned to this grouping: C. kneri Mayr , C. bequaerti Forel , C. concava Emery , C. luctans Forel and C. chlorotica Emery.
