Abstract
Taxonomic inventories are the basis of several ecological studies and they enable a better understanding of the local and regional biodiversity. This paper aimed to survey the aquatic insect fauna in a subtropical island, as well as to generate information on the habitats used by the taxa found. Two regions showing a good state of environmental conservation in the Santa Catarina Island, in Santa Catarina, Brazil, were selected: “Lagoa do Peri” Municipal Park and “Desterro” Environmental Protected Area. Aquatic invertebrates were collected by using a Surber sampler (in a lotic environment) and an Eckman-Birge dredger (in a lentic environment) between 2009 and 2012. Sixty taxa were found, belonging to eight taxonomic orders. Thus, there were 19 new registers of aquatic insect families for Santa Catarina. At the sites of this study, 13 families already known for Santa Catarina were not observed, according to a comparison with articles published until July 2014. As for the habitat, richness differed between the types of the habitats sampled, with lower richness in the substrate “sand”. The study represents a significant contribution to knowledge on aquatic insects in Santa Catarina, especially regarding the biodiversity in islands.

Summary
O estudo foi realizado em duas áreas em bom estado de conservação da Ilha de Santa Catarina, SC. Estas áreas estão compreendidas pelo Parque Municipal da Lagoa do Peri (PMLP), na porção sul da ilha, e pela Unidade de Conservação Ambiental Desterro (UCAD), na porção norte da ilha (Figura 1). É o maior manancial de água doce da Ilha de Santa Catarina e apresenta um espelho d’água de 5,7 km rodeado por morros cobertos por Mata Atlântica e uma restinga típica de vegetação litorânea, que está 3 m acima do nível do mar separando a lagoa do mesmo (LISBOA et al, 2011). O ambiente lêntico foi representado pela Lagoa do Peri, cujas, coletas foram realizadas no período de março 2008 a junho de 2009 com draga de Eckman-Birge (0,0625 m2), em cinco áreas que melhor representam os diferentes biótopos da lagoa, totalizando 16 amostras. Para identiicação dos insetos aquáticos no nível taxonômico de família foi utilizada bibliografia especializada (DOMÍNGUEZ; FERNÁNDEZ, 2009; MUGNAI et al, 2010) e auxílio de especialistas
