Aphaenogaster gibbosa group
- Aphaenogaster gibbosa
- Aphaenogaster gibbosa homonyma
- Aphaenogaster theryi
- Aphaenogaster italica
- Aphaenogaster striativentris
- Aphaenogaster muschtaidica
- Aphaenogaster mauritanica
- Aphaenogaster nadigi
- body colouration from dark brown, reddish black to black;
- head with longitudinal rugae or reticulation at least on its anterior part of head dorsum, sometimes rugae and reticulation replaced or co-occurring with punctuation;
- funicular segments from 1.5 to 2 times longer than wide;
- surface between rugae with dense micropunctuaction or smooth and shiny;
- scape reaches at least 1/5 of its length over the occipital margin of head;
- propodeal spines always present, short, triangular, inclined at an 45° angle, with wide base.
Males of Aphaenogaster gibbosa and Aphaenogaster muschtaidica are also characterized by extremely gibbous mesosoma. Unfortunately, males of other species of the gibbosa group are unknown. Therefore, we are not able to confirm whether this feature is characteristic for all the representatives of this group.
