New records of semi-aquatic bugs (Hemiptera, Heteroptera, Gerromorpha) from the South Region of Brazil.

ABSTRACT:

Background

Semi-aquatic bug (Hemiptera, Heteroptera, Gerromorpha) constitute a monophyletic group of predatory insects that play crucial roles in limnic environments. The Oriental and Neotropical regions harbor the richest faunas, but many species from these areas remain undescribed, and large regions are still poorly explored. In Brazil, semi-aquatic bugs have been more thoroughly sampled in the North and Southeast regions, while other regions have been neglected. The Southern Region of the country comprises the states of Paraná, Santa Catarina, and Rio Grande do Sul, from which 20, 44, and 28 species of Gerromorpha have been recorded, respectively. In total, 61 species are known from the region, which is likely far from being an accurate representation of the local fauna.
