Identification

Terayama (1999) - Total length around 4 mm in mmor workers, and 5.5 -6 mm in major workers. In major workers: head, mesosoma, and legs reddish brown; 1st gastral tergite yellowish brown excepting posterior margin blackish brown to black; 2nd to terminal segments blackish brown to black (2nd tergite with a pair of small yellow spots in a few individuals). Dorsum of mesosoma moderately convex in profile; pronotal dorsum with several relatively short erect hairs; mesonotal dorsum with 4-6; propodeum with more than 10 erect hairs; petiolar scale thin and high. In minor workers: head, mesosoma, and legs light yellowish brown; coloration of gaster as in major worker.
