Acromyrmex Mayr (Hymenoptera: Formicidae: Myrmicinae): Species distribution patterns in the province of Buenos Aires, Argentina

The Attini, mainly the genera Atta Fabricius and Acromyrmex Mayr, are called leaf-cutting ants. Acromyrmex has scarce records referring to the geographical distribution of its species in Buenos Aires province. The objective of the present work was to gather existing information, to update these data...

To perform a hierarchical classification of similarities in the distribution patterns of the species, binary data matrices were constructed, analyzed by the weighted average method, calculating squared euclidean distances.

Eleven species of ants of the genus Acromyrmex are present in the province of Buenos Aires: A. ambiguus, A. fracticornis, A. heyeri, A. hispidus, A. hystrix, A. landolti, A. lobicornis, A. lundii, A. rugosus, A. silvestrii and A. striatus. The genus Acromyrmex is characterized by nesting in the soil, whereby anthropic practices for productive, industrial and urban purposes directly affect its pattern of occurrence. © 2017 Museo Argentino de Ciencias Naturales Bernardino Rivadavia.
