This is a very small ant, almost the same size as the Ghost Ant (Tapinoma melanocephalum) except that its body is much slender and it usually moves in a straight line instead of erratic movement as that seen in the Ghost Ant. The picture below showed its size (the smaller ants) when compared to the Black Crazy Ant (Paratrechina longicornis).
