Key to workers and queens of Malagasy Odontomachus  HNS  (modified from Brown [ 1:117]

1. Head narrow behind eyes; mandible with long, acute apical and preapical teeth; vertex of head coarsely, transversely striate............................... coquereli  HNS 

Head only slightly narrower across vertex than across eyes, with distinct extraocular furrows and temporal ridges; apical and preapical teeth of mandible short and blunt; vertex finely striate longitudinally, diverging behind ............... 2

2. Metasternal process acute, forming paired, slender spines, often unequal in length (Fig. 13a). Petiole spine notably bent posteriorly at base...................... troglodytes  HNS

Shortest distance between lateral ocellus and margin of compound eye distinctly greater than maximum length of ocellus. Antenna with very short appressed to decumbent setae; declivitous surface of propodeum with distinct rugae directed towards margins ............................... 2

2. Body brownish yellow. Tarsal claw with small subapical tooth (Madagascar) ......................... troglodytes  HNS
