Mesoveliidae

Mesoveliidae is represented in Argentina by two species of Mesovelia (Coscarón 2017); the genus Mesoveloidea was recorded from this country (Andersen 1982), but no species have been mentioned until now. Estévez et al. (2003) and Poi de Neiff (2003) previously reported both species of Mesovelia from INR, one of which was not collected during this study: M. bila Jaczewski, 1928 .
