The terrestrial flatworm (Tricladida, Geoplanoidea), slug (Mollusca, Gastropoda),diplopodan (Myriapoda, Diplopoda), symphilan (Myriapoda, Symphylla) and spider(Chelicerata) faunas of Buenos Aires City (CABA, Argentina) are poorly known. Theaim of the present contribution is to report new records of exotic species belonging to those clades. Collection and observation of specimens were made withouta systematic method. The following species are reported: Rhynchodemus sylvaticus(Tricladida, Geoplanidae; first record for Buenos Aires province and second recordfor tArgentina), Obama nungara (Tricladida, Geoplanidae; CABA), Imbira flavonigra(Tricladida, Geoplanidae; first record for Argentina), Milax gagates (Mollusca, Milacidae; first record for CABA), Cylindroiulus latestriatus (Diplopoda, Julidae; first recordfor Argentina), Ophyiulus pilosus (Diplopoda, Julidae; first record for Argentina),Brachydesmus superus (Diplopoda, Paradoxomatidae; first record for CABA and second record for tArgentina), Symphylella vulgaris (Symphyla, Scolopendrellidae; firstrecord for Argentina), Cylisticus convexus (Oniscidea, Cylisticidae; second record forthe city by most than 90 years), Uloborus plumipes (Arachnida, Uloboridae; secondrecord for CABA and the country), and Leucauge argyra (Arachnida, Tetragnathidae;first record for Buenos Aires province and second record for Argentina). Several authors have indicated that the number of exotic invertebrates in European cities hasbeen dramatically increased in the last years. This pattern should be extrapolated toArgentina. Unfortunately, up to the date we entirely lack information about dispersaland distribution of exotic invertebrates in the city. It is necessary to prioritize thestudy of exotic species, especially those that are potentially problematic for nativeenvironments.
