 167 OCCURRENCE OF THE SOCIAL PARASITE PSEUDOATTA ARGENTINA (FORMICIDAE: MYR-MICINAE) IN THE STATE OF RIO GRANDE DO SUL, BRAZIL  A. L. M. JÚNIOR1, P. R. V. S. PEREIRA1, T. E. D. MARQUES2, 3, A. F. R.

Between the few social parasites currently known, Pseudoatta argentina Gallardo, 1916 is the one that is known for the longest time, exclusively from northern Argentina. Until now, it was found associated with the fungus-growing ants Acromyrmex lundii (Guérin-Méneville, 1838) and Acromyrmex heeri (Forel, 1899). Recently (29/06/2015), the assemblage of soil-dwelling ants in an oilseed rape (Brassica napus L. var. oleifera, Brassicaceae) plantation was sampled using pit-fall traps on the experimental areas of Embrapa Trigo in the municipality of Passo Fundo, state of Rio Grande do Sul, Brazil. A single specimen of a female of P. argentina was collected. It was preserved in the CEPEC collection under the number #5793 (as oth-er vouchers of the ant species collected during the same experiment). Other Acromyrmex which ap-peared together in the sampling series (but not in the same trap that P. argentina) were Acromyrmex aspersus (Smith, 1858) and Acromyrmex crassispinus (Forel, 1909), but there is no evidence that P. argentina could parasite one or the other of these species. This record extends to the north the known distribution of the ant and suggests that it could be found in association with other species of Acromyr-mex that the ones known until now. (CNPq, EMBRAPA).
