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. Lacking ventral notch anterior to eyes. Mandibles linear; armed with apical fork and 1 preapical tooth; very straight with an abrupt attenuation near insertion of preapical tooth. Pronotal spines absent. Propodeum armed with spines or teeth. Waist 2-segmented. Petiole and postpetiole with distinct spongiform. Hairs on petiole, postpetiole and gaster flagellate. Appressed circular hairs do not cover face, mesosoma and waist segments.

Strumigenys lanuginosa can be separated from other introduced and commonly intercepted Strumigenys species by the following combination of characters: (1) mandibles linear; (2) mandibles with apical fork and 1 preapical tooth; (3) hairs on petiole, postpetiole and gaster flagellate; and (4) mandibles very straight with an abrupt attenuation near insertion of preapical tooth. This last character separates S. lanuginosa from the similar appearing S. godeffroyi and S. lewisi.

Lateral view of head, adult worker. The ventral margin of the head is entire and lacks a distinct notch just anterior to the eyes. Used in Antkey to separate Strumigenys godeffroyi , Strumigenys lanuginosa , Strumigenys lewisi and Strumigenys silvestrii from Strumigenys rogeri .
