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...

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. 2017 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_15145158_v19_n2_p185_CulebraMason http://hdl.handle.net/20.500.12110/paper_15145158_v19_n2_p185_CulebraMason |
