|
Total length of workers 4.5-5.5 mm. Body light brown, the head and gaster slightly darker. Legs yellow. As seen from above a large gap separates the pronotum from the mesonotum. This species is not separable from A. concolor in worker morphology but the two differ in chromosome number (2n=26 in kumejimana, 2n=30 in concolor).

Remarks

|
This species nests in rotting wood, tree holes etc. Workers turn their gasters downwards while foraging, and perform death-feigning behavior.
