Resumen:
We analyze the geographic distribution of Leptasthenura platensis and L. aegithaloides in Argentina, with special reference to localities where these two species have been found together. We present the geographical distribution on a dot-map showing known localities of occurrence for L. platensis (147 localities) and for L. aegithaloides (148). Both species are distributed in dry xeric environments. We provide the second record of L. platensis in Mendoza Province, identifying the species through the examination of mist-netted birds and by an analysis of their voice. We confirm previous information about four sympatric localities, and report a new sympatric site. We also present other localities in which these species are probably sympatric. We found that L. platensis and L. aegithaloides are sympatric or potentially sympatric in Espinal and Monte areas, specially in central and east-central Argentina.
