Abstract
The presence of <i>Thinocorus rumicivorus bolivianus</i> is confirmed, from the extreme north of Argentina to the Northwest of Mendoza, where a pair was taken during the breeding season. The geographieal distribution of <i>Thinocorus orbignyianus ingae</i> is extended further to the south, in Northwestern Mendoza, and we show that the typical subspecies ranges from the south of Argentina to the south center of that province
