Paratrechina

Paratrechina contains a single species, P. longicornis. This is a widespread tramp in many tropical countries, being introduced through human activity. While primarily an environmental pest, it can sometimes be a household nuisance as well.

Identification
Upper surface of the head and body with pairs of large, stout, dark hairs. Node of petiole strongly inclined forward and with the anterior face much shorter than the posterior face. Scapes lacking erect hairs. Mandibles with 5 teeth. Erect hairs absent from propodeum. Erect setae on front of head scattered across surface and not forming pairs. Legs with numerous erect hairs.

Paratrechina is most often confused with Nylanderia and Paraparatrechina. It can be separated from Nylanderia by the lack of erect hairs on the scapes and in having only 5 mandibular teeth (6 or 7 teeth are present in Nylanderia). It can be separated from Paraparatrechina by the lack of erect hairs on the legs. It differs from both of these in having much longer scapes.
