Key to Genera of Malagasy males of subfamily Ponerinae

1. Wings absent................................................................................ Hypoponera (part 02; ergatoid males)

- Wings present.......................................................................................................................................... 2

2. Mandibles stout and fully developed, masticatory margins overlap completely when mandibles fully closed. Antennal scrobe well defined ( Figs. 10 a, b) and extends as long as length of antennal scape. .. .. ................................................................................................................................................ Platythyrea

- Mandibles very reduced in size and “lobate,” the masticatory margins do not overlap completely when mandibles are fully closed. Antennal scrobe absent ( Fig. 7 e); if weakly defined, then length distinctly shorter than length of antennal scape ....................................................................................................... 3

3. Pretarsal claw multidentate to pectinate ( Fig. 7 b) .................................................................. Leptogenys

- Pretarsal claw edentate or with at most two preapical teeth ( Fig. 9 e) .................................................... 4

4. Hind wing with jugal lobe ( Fig. 1 c)........................................................................................................ 5

- Hind wing without jugal lobe (as in Fig. 7 g).......................................................................................... 8

5. Notauli present on mesoscutum ( Fig. 9 h)........................................................... Pachycondyla (part 02)

- Notauli absent ( Fig. 9 c)........................................................................................................................... 6

6. Apical portion of abdominal tergum VIII not forming spine ( Fig. 5 e) ................................... Anochetus

- Apical portion of abdominal tergum VIII forming distinct spine ( Fig. 8 e) ............................................ 7

7. Body usually yellow ( Madagascar), rarely black ( Seychelles); petiole more or less conical in frontal view, with single, narrowly rounded or sharp apex ( Fig. 8 b) .......................................... Odontomachus

- Body black; petiole in frontal view with dorsal margin broadly or bluntly rounded ( Fig. 9 d).................. ............................................................................................................................ Pachycondyla (part 01)

8. Apical portion of abdominal tergum VIII without down-curved spine ( Fig. 6 b) .. Hypoponera (part 01)

- Apical portion of abdominal tergum VIII with down-curved spine ....................................................... 9

9. Hind tibia with one spur (as in Fig. 6 d) ........................................................................................ Ponera

- Hind tibia with two spurs (as in Fig. 7 c).................................................... Pachycondyla (part 0 3 & 04)
