Exotic invertebrates in the city of Buenos Aires. First steps for the monitoring ofpotential biological invasions. Invasive species can cause several problems at thesocio-economic level and for the biodiversity conservation. The early detectionof naturalized species can be of vital importance for the planning of containmentstrategies of the invasion process. The flat worms (Tricladida, Geoplanoidea), landslugs (Mollusca, Limacidae), millipedes (Myriapoda, Diplopoda) and symphillids(Myriapoda, Symphyla) of the Ciudad Autónoma de Buenos Aires it is little studied,and the addition of exotic species transported by human activities complicates thesituation of little knowledge. In this work, we present new records of species of thesegroups that have become naturalized in the urban area of the city and its surroundings (Bipalium kewense, Austroplana sanguinea, Ambigolimax valentianus, Brachyiuluspusillus, Oxidus gracilis y Scutigerella immaculata). The invasive potential of each species was evaluated based on what was registered in other countries. Until the datethere are no published records of terrestrial flat worms, symphillids, or millipedesfor this area, for which the present work constitutes the first contribution on thesegroups. The aforementioned species damage agricultural and horticultural activitiesin different ways. A future task should be the quantification of the damage causedto establish its importance and the cost / benefit of its control or management.
