Passos and Leal (2019) - This species was found attending extrafloral nectaries of the plant Turnera subulata in northeastern Brazil (12°16′24″S 38°57′20″W / 12.27333°S 38.95556°W / -12.27333; -38.95556) Caatinga vegetation. Pseudomyrmex termitarius was classified as a subordinate species and was infrequently observed.
