Key to the genera of Myrmicinae occurring in the UAE (workers)
1 Postpetiole attached mediodorsally to the first gaster tergite ( Fig. 19View Figures 19–27. 19); gaster heart-shaped from above ( Fig. 20View Figures 19–27. 19) ........................................................................... Crematogaster Mayr
– Postpetiole attached medioventrally to the gaster ( Fig. 22View Figures 19–27. 19) which is pear-shaped in dorsal view ( Fig. 21View Figures 19–27. 19) .................................................................................................................... 2
2 Antennae 10-segmented, the two apical segments forming a distinct club ( Fig. 23View Figures 19–27. 19). .......... ........................................................................................................... Solenopsis Westwood
– Antennae 11- or 12-segmented with a three segmented club ( Fig. 24View Figures 19–27. 19) or with a less well defined club of five thickened segment ............................................................................. 3
3 Mandibles, in full-face view, broadly rounded or flat ( Fig. 25View Figures 19–27. 19). Workers polymorphic with head width increasing allometrically with increasing body size .................... Messor Forel
– Mandibles, in full-face view, triangular ( Fig. 26View Figures 19–27. 19). Workers monomorphic or dimorphic. 4
4 Clypeus longitudinal bicarinate ( Fig. 27View Figures 19–27. 19). Propodeum without spines or teeth ( Fig. 28View Figures 28–35. 28) ..... .............................................................................................................. Monomorium Mayr
– Clypeus with median portion rounded or flat ( Fig. 29View Figures 28–35. 28). Propodeum bituberculate or with distinct spines or teeth ( Fig. 30View Figures 28–35. 28) ........................................................................................ 5
5 Clypeus raised into a ridge in front of antennal insertions ( Fig. 32View Figures 28–35. 28) ..... Tetramorium Mayr
– Clypeus not raised into a ridge in front of antennal insertions .......................................... 6
6 Dimorphic species; major workers have greatly enlarged incavate heads broad, threetoothed mandibles ( Fig. 31View Figures 28–35. 28). Minor workers have narrow heads with long multidentate mandibles ( Fig. 33View Figures 28–35. 28) .............................................................................. Pheidole Westwood
– Monomorphic species; all workers in a colony of more or less even size and shape, having mandibles of five teeth. ...................................................................................................... 7
7 Postpetiole enlarged, in most species wider than long in dorsal view and cordiform ( Fig. 34View Figures 28–35. 28). Mid body entirely without dorsal hairs ..................................... Cardiocondyla Emery
– Postpetiole not conspicuously enlarged ( Fig. 35View Figures 28–35. 28). Body hairs present over whole dorsum. ................................................................................................................. Leptothorax Mayr
