Species: Strumigenys hexamera (Brown, 1958)
Head shape triangular. Antenna 6-sgemented. Antennal club 2-segmented. Antennal scapes not conspicuously short; easily extended beyond eye level. Antennal insertions at least partly covered by frontal lobes. Eyes medium to large (greater than 5 facets); situated on lower margin of scrobe. Frontal lobes do not obscure face outline between mandible and eye. Posterolateral corners of head unarmed, without spines. Mandibles linear but short and strongly tapered; armed with small denticles and no apical fork. Pronotal spines absent. Propodeum armed with spines or teeth. Waist 2-segmented. Petiole and postpetiole with distinct spongiform. Appressed circular hairs cover face, mesosoma and waist segments.
Strumigenys hexamera can be separated from other introduced and commonly intercepted Strumigenys species by the following combination of characters: (1) mandibles linear (although short and strongly tapered); (2) mandibles with denticles, lacking apical fork; and (3) appressed circular hairs cover face, mesosoma and waist segments. Strumigenys emmae is superficially similar because it also has appressed circular hairs, but S. hexamera is easily distinguished by the mandibles armed with many denticles and no apical fork (versus one preapical denticle and an apical fork).
