Pampa plain is extended between ca. 33° to 39°S and 57° to 66°W and shallow lakes arethe dominant aquatic ecosystem of the region. These water bodies are mainly influencedby inter-annual variations in rainfall, and constitute great biodiversity reservoirs. TheChironomidae (Diptera) have so far received limited attention in terms of their ecologicallyand taxonomically knowledge, in contrast to other regions of Argentina where they arebeen widely studied as bioproxy or complementary indicators in paleoenvironmentalreconstructions, and in environmental quality studies. In this opportunity, we present thefirst checklist of the Chironomidae from the Pampa plain. The cataloged fauna contains19 genera and 3 subfamilies for modern fauna and 16 morphotypes in 13 genera and 3subfamilies for subfossil Chironomidae, based on non- intensive samplings of Chironomidaelarvae and adults, from 22 shallow lakes and the surrounding habitats in the central-southarea of Pampa Plain.
