Abstract:

Resumen: La fauna de planarias terrestres (Tricladida, Geoplanoidea), babosas (Mollusca, Gastropoda), diplópodos (Myriapoda, Diplopoda), sínfilos (Myriapoda, Symphylla) y arácnidos (Chelicerata) de la Ciudad Autónoma de Buenos Aires (CABA, Argentina) permanece pobremente conocida. En la presente contribución se dan a conocer nuevos registros de especies de estos grupos, naturalizadas en el ámbito urbano de CABA y alrededores. Las colectas y observaciones fueron realizadas sin un método sistemático. Se reportan: Rhynchodemus sylvaticus (Tricladida, Geoplanidas; primer registro para la provincia de Buenos Aires y segundo para Argentina), Obama nungara (Tricladida, Geoplanidae; primera cita para CABA), Imbira flavonigra (Tricladida, Geoplanidae; primer registro para Argentina), Milax gagates (Mollusca, Milacidae; primer registro para CABA), Cylindroiulus latestriatus (Diplopoda, Julidae; primer registro para Argentina), Ophyiulus pilosus (Diplopoda, Julidae; primer registro para Argentina), Brachydesmus superus (Diplopoda, Paradoxomatidae; primer registro para CABA y segundo para Argentina), Symphylella vulgaris (Symphyla, Scolopendrellidae; primer registro para Argentina), Cylisticus convexus (Oniscidea, Cylisticidae; segunda cita para Argentina, luego de 90 años), Uloborus plumipes (Arachnida, Uloboridae; segunda cita para CABA y para Argentina) y Leucauge argyra (Arachnida, Tetragnathidae; primera cita para la provincia de Buenos Aires y segunda cita para Argentina). Diversos autores indican para Europa un rápido incremento en el número de especies invertebradas introducidas, un patrón extrapolable a Argentina. Lamentablemente, hasta la fecha, no se cuenta con datos certeros acerca de los patrones de distribución o abundancia de estas especies. En este sentido es necesario priorizar su conocimiento, incluso de aquellas potencialmente perjudiciales para ambientes nativos.

New or Little Known Exotic Invertebrates (Tricladida, Gastropoda, Diplopoda, Symphyla, Isopoda, Arachnida) in Buenos Aires City, Argentina

Abstract: The terrestrial flatworm (Tricladida, Geoplanoidea), slug (Mollusca, Gastropoda), diplopodan (Myriapoda, Diplopoda), symphilan (Myriapoda, Symphyla) and spider (Chelicerata) faunas of Buenos Aires City (CABA, Argentina) are poorly known. The aim of the present contribution is to report new records of exotic species belonging to those clades. Collection and observation of specimens were made without a systematic method. The following species are reported: Rhynchodemus sylvaticus (Tricladida, Geoplanidae; first record for Buenos Aires province and second record for 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 record for Argentina), Ophyiulus pilosus (Diplopoda, Julidae; first record for Argentina), Brachydesmus superus (Diplopoda, Paradoxomatidae; first record for CABA and second record for Argentina), Symphylella vulgaris (Symphyla, Scolopendrellidae; first record for Argentina), Cylisticus convexus (Oniscidea, Cylisticidae; second record for the city by most than 90 years), Uloborus plumipes (Arachnida, Uloboridae; second record 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 has been dramatically increased in the last years. This pattern should be extrapolated to Argentina. Unfortunately, up to the date we entirely lack information about dispersal and distribution of exotic invertebrates in the city. It is necessary to prioritize the study of exotic species, especially those that are potentially problematic for native environments.
