Specimen Labels

Known only from the holotype worker, it was collected from a Tillandsia.


Bolton (2000) - A member of the Strumigenys tococae-group. Easily recognised within the group by its sculptured gaster combined with the lack of a ventral spongiform crest or curtain on the petiole. Two other species in the group, Strumigenys fairchildi and Strumigenys anthocera, also have the first tergite densely sculptured, but both of these have a ventral petiolar spongiform crest. Also, both these species lack appressed spatulate gastral hairs that are similar to those on the cephalic dorsum; such spatulate gastral hairs are conspicuous in usbensis.

First gastral tergite also with a few fine short-flagellate hairs that are apparently easily lost. Apicoscrobal hair absent. Maximum diameter of eye ca 0.12. Propodeum in profile with a pair of triangular teeth at top of declivity that are slightly longer than the pair at the base of the declivity.
