Plagiolepis alluaudi is a tiny Old World ant that has spread to many parts of the world through human commerce. It is a primarily tropical species, apparently native to Madagascar and neighboring islands. It has become a pest on Pacific islands and in European greenhouses (Wetterer, 2013).

There is a single record of this species from Catalina Island, California (collected by William M. Mann; SMITH 1957). Many researchers have made extensive ant collections in California, but have never produced another record of P. alluaudi, suggesting that either the California population has been extirpated or the one record was based on a labeling error. In fact, this one record of P. alluaudi is very suspect: I have been unable to find any other records of ants collected by William M. Mann on Catalina Island (Wetterer 2013).
