Description
|
|
Total length of workers around 2 mm. Body color yellowish to reddish brown from head to postpetiole; gaster darker. Antennae 11-segmented. Anterior margin of clypeus without median notch. Lateral margin of mesosoma sinuate; mesonotal region expanded laterally in dorsal view. Propodeal spines acute, directed posteriorly. Sculpture somewhat coarse, longitudinally rugulose.

Remarks
|
|
This is the "Xyphomyrmex sp." of Onoyama (1976). T. smithi workers are similar to those of T. kraepelini in general appearance and size, but they are separable by the different number of antennal segments (11 versus 12), the inclination of the propodeal spines, the angulate petiolar node in profile, and the broad and angulate postpetiole in dorsal view. Found in rather open habitats (Onoyama, 1980).
