Specimen Labels

V. brevis appears to nest in dead twigs on the surface of the ground in rainforest. It has also been retrieved from leaf litter samples and has been discovered foraging on low vegetation.


Very similar to, and mostly matching the description of, Vitsika producta, but with an obviously 3-segmented antennal club, in which funiculus segment 8 is only 1.00–1.25 times longer than broad, and funiculus segment 9 is relatively elongated, 1.70–2.00 × longer than funiculus segment 8. The antennal scape is relatively shorter in brevis, SI 99–111, than in producta, SI 115–129. In addition, the head capsule of producta averages relatively slightly narrower, CI 75–80, as opposed to CI 79–85 in brevis.

Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.

Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.



Known only from the worker caste.
