Habitat/Ecology. This species was found in primary and/or old/mature secondary forests in Singapore. Individuals were mostly collected from leaf litter.

Remarks. Some specimens examined were observed to have petiole in profile elongate with nearly flat dorsal margin, closely resemblant of Probolomyrmex itoi or P. longiscapus . However, the same specimens in dorsal view each had posterodorsal margin of petiole medially produced into a horn, a feature unique to and diagnostic of P. watanabei .
