Assemblages of oribatid mites in ant nests of Acromyrmex spp. (Hymenoptera, Formicidae)
Nests of Acromyrmex spp. exhibit aboveground elevations (tumulus) which maintain a stable microclimate, offering an attractive environment for oribatids and other soil invertebrates. We studied assemblages of Oribatid mites (Acari: Oribatida) in tumuli of two species of Acromyrmex in Integral Reserve Laguna de Los Padres, Buenos Aires province. Samples from nests of Acromyrmex lundii and A. ambiguus, and from their surrounding soil revealed the presence of 1440 oribatids belonging to 18 families, 25 genera and 34 species. Three of the species had not been previously described. Oribatid mites was the most abundant group and were more abundant on tumulus than in the surrounding soil. Conversely, its richness, diversity and evenness did not differ between sites or between ant species. The species composition varied between sites but the most abundant species were the same in tumuli and soil. We found an inverse relationship between density of substrate (tumulus or soil) and density of Oribatida. Potential myrmecophilous species were identified.

Nests of Acromyrmex spp. exhibit aboveground elevations (tumulus) which maintain a stable microclimate, offering an attractive environment for oribatids and other soil invertebrates. We studied assemblages of Oribatid mites (Acari: Oribatida) in tumuli of two species of Acromyrmex in Integral Reserve Laguna de Los Padres, Buenos Aires province. Samples from nests of Acromyrmex lundii and A. ambiguus, and from their surrounding soil revealed the presence of 1440 oribatids belonging to 18 families, 25 genera and 34 species. Three of the species had not been previously described. Oribatid mites was the most abundant group and were more abundant on tumulus than in the surrounding soil. Conversely, its richness, diversity and evenness did not differ between sites or between ant species. The species composition varied between sites but the most abundant species were the same in tumuli and soil. We found an inverse relationship between density of substrate (tumulus or soil) and density of Oribatida. Potential myrmecophilous species were identified.

Los hormigueros de varias especies de Acromyrmex presentan sobre el suelo una elevación (túmulo), que posee condiciones micro climáticas estables y ofrece un ambiente atractivo para ácaros oribátidos y otros invertebrados edáficos. Estudiamos los ensambles de oribátidos (Acari: Oribatida), otros ácaros y artrópodos en túmulos de dos especies de Acromyrmex en la Reserva Integral Laguna de Los Padres, Provincia de Buenos Aires. A partir de muestras del túmulo de hormigueros de Acromyrmex lundii y A. ambiguus y del suelo circundante, encontramos 1440 oribátidos pertenecientes a 18 familias, 25 géneros y 34 especies (tres de ellas no habían sido descriptas antes). Los oribátidos fueron el grupo más abundante y su abundancia fue el único parámetro que resultó mayor en los túmulos que en el suelo circundante. En cambio, su riqueza, diversidad y equitatividad no se diferenciaron entre sitios o entre especies de hormiga. La composición de especies de oribátidos varió entre sitios pero las especies más abundantes fueron las mismas en el túmulo y el suelo. Se halló una relación inversa entre la densidad del sustrato (túmulo o suelo) y la densidad de Oribatida. Se sugieren posibles especies mirmecófilas.
