Diagnostic description

Diagnosis of worker among Antkey species

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; armed with small denticles and no apical fork. Pronotal spines absent. Propodeum armed with spines or teeth. Waist 2-segmented. Postpetiole with distinct spongiform. Appressed circular hairs do not cover face, mesosoma and waist segments. Strumigenys gundlachi can be separated from other introduced and commonly intercepted Strumigenys species by the following combination of characters: (1) mandibles linear; (2) mandibles with denticles, lacking apical fork; (3) appressed circular hairs do not cover face, mesosoma and waist segments; and (4) spongiform on postpetiole. Strumigenys eggersi appears similar, but S. gundlachi is distinguished by the presence of spongiform on the postpetiole (versus complete lack spongiform present on the waist).
