Technomyrmex vitiensis is an “accomplished tramp” ant (Bolton 2007) in the family Formicidae that is widespread across Southeast Asia, on the continent and islands from the Indian Ocean to Polynesia, and in some European greenhouses (Bolton 2007; Wetterer 2008).  It is one of two species of the large genus Technomyrmex (90+ species) to have invaded the New World; first reported in the Golden Gate Park Conservatory, San Francisco, California (Bolton 2007).  It has since been collected in two remote inland forest sites in French Guiana, though it is not clear how it got there.  Delabie et al. (2011) hypothesize that it was introduced by way of trade routes through overseas French territories. 

This species (as is the case with closely related T. difficilis) has been frequently misidentified as the very similar T. albipes in museum collections and in the literature (Wetterer 2008; Delabie et al. 2011).

Technomyrmex vitiensis nests and forages in a broad spectrum of locations, on the ground in leaf litter, under rocks, in dead wood and up in vegetation.  Like other ants in the species group Albipes (to which T. difficilis belongs), it uses a technique of colony reproduction that is unique in the Formicidae which involves production of “reproductive worker-queen intercast” individuals allowing colonies to multiply quickly by fissioning into multiple nests and reproducing in large numbers.  Colonies cover large areas, populating diverse ecosystems and negatively impact pollinators, pollination and seed dispersal, and other ant species (Bolton 2007).  Scientists expect that like its close relative, T. difficilis which has spread quickly through the southern United States and West Indies, T. vitiensis will also rapidly disperse from French Guiana, potentially invading Brazil and Surinam (Delabie et al. 2011).

Diagnosis among workers of introduced and commonly intercepted species. Antenna 12-segmented. Antennal scape length less than 1.5x head length. Eyes medium to large (greater than 5 facets); eye length distinctly greater than length of erect hairs on frontal carinae. Antennal sockets and posterior clypeal margin separated by a distance less than the minimum width of antennal scape. Mandible lacking distinct basal angle. Dorsum of mesosoma with metanotal groove, but never with a deep and broad concavity; erect hairs present. Propodeum and petiolar node both lacking a pair of short teeth. Propodeum lacking posteriorly projecting protrusion; with dorsal surface distinctly shorter than posterior face. Waist 1-segmented (may be hidden by gaster). Petiolar node appearing flattened. Gaster armed with ventral slit; with five plates on its dorsal surface. Distinct constriction not visible between abdominal segments 3+4. Dorsum of head lacking erect hair posterior to eye. Pronotum with 1 pair of erect hairs. Mesonotum lacking erect hairs. Propodeum with 1 pair of erect hairs. Color uniformly dull brown with paler antennae, trochanters and tarsi; hind tarsus distinctly lighter in color than hind femur.

Technomyrmex vitiensis can be distinguished from Brachymyrmex species, with which it bears superficial resemblance, by the 12-segmented (versus 9-segmented) antenna, and by the presence of a ventral slit (versus acidopore) on the gaster tip. It can be differentiated from Technomyrmex species by the absence (versus presence) or erect hairs on the mesosoma, and by the gaster which has 4 plates on the dorsal surface and 6 on the ventral surface (versus 5 plates on both surfaces). It is most easily differentiated from Tapinoma sessile by the bicolored with dark head and light body, gaster and appendages (versus uniform brown color). Technomyrmex vitiensis is distinguished from its fellow introduced congeners by the following combination of characters: (1) no erect hairs on head posterior to eye level; (2) 1 pair of erect hairs on pronotum, 1 pair of propodeum, no erect hairs on mesonotum,; (3) hind tarsus distinctly lighter in color than hind femur; and (4) eye length is distinctly greater than length of erect hairs on frontal carinae. The species is most readily confused with T. albipes, and is most reliably distinguished by the larger eye size.
