Key to the subfamilies of ants of the United Arab Emirates (workers)

1 Eyes absent ( Plate 1View Plates 1–6. 1, Fig. 3View Figures 3–14.3). Minute ants; length generally less than 2 mm and head width less than 0.25 mm in all castes ...................................................................... Leptanillinae 

– Eyes present ( Plate 2View Plates 1–6. 1, Fig. 5View Figures 3–14.3) ............................................................................................. 2

2 Peduncle with a single node or scale ( Plate 3View Plates 1–6. 1, Fig. 4View Figures 3–14.3) ....................................................... 4

– Peduncle with two distinct segments, the petiole and the postpetiole ( Plate 4View Plates 1–6. 1, Fig. 6View Figures 3–14.3) ..... 3

3 Clypeus projects back between the frontal ridges ( Plate 5View Plates 1–6. 1, Fig. 7View Figures 3–14.3); tarsal claws simple. Ocelli absent in worker caste. In most species eyes small to medium sized ... Myrmicinae 

– Clypeus does not project back between frontal ridges but bends vertically downwards in front of the head. Eyes large, at least one third head length ( Plate 6View Plates 1–6. 1, Fig. 8View Figures 3–14.3) ........................ ............................................................................................................. Pseudomyrmecinae

– Gaster without a projecting sting. First and second gaster tergites not separated by a distinct constriction ( Plate 8View Plates 7–11. 7, Fig. 10View Figures 3–14.3) ................................................................................ 6

5 Pygidium (last visible gaster tergite) rounded without short projecting teeth or spines. Antennal insertions concealed by frontal laminae in dorsal view ( Plate 9View Plates 7–11. 7, Fig. 11View Figures 3–14.3) ............. ............................................................................................................................. Ponerinae 

– Pygidium flattened, armed with very short spines or peg-like teeth. Antennal insertions exposed ( Plate 10View Plates 7–11. 7, Fig. 12View Figures 3–14.3) ........................................................................ Cerapachyinae 

6 Gaster with a fringe of hairs on the ultimate gastral segment (acidopore) ( Plate 11View Plates 7–11. 7) ........... .......................................................................................................................... Formicinae 

– Gaster without a fringe of hairs on the ultimate gastral segment ............... Dolichoderinae
