Mesovelia bila Jaczewski, 1928

Mesovelia bila Jaczewski, 1928: Ann. Mus. Zool. Polonici, 77–79.

General distribution. Brazil, Argentina (Damgaard et al. 2012).

Habitat. Little information exists regarding the habitat associations of this species. Jaczewski (1928) reported the first collections of M. bila from a very shallow and small pool in a forest. Subsequent reports of collections were made from lentic habitats, on floating aquatic plants in small pools (Harris & Drake 1941) and at the margins of unshaded marshlands with dense vegetation (Torres et al. 2007). This species was also collected from lotic habitats, in standing or slow-moving water along the margins of streams and artificial channels with emergent and submerged vegetation (Fernández & López Ruf 2006) and in shaded streams without aquatic vegetation (Torres et al. 2007).

In INR, specimens were collected from the margins of the Iberá Lagoon in shallow waters with emergent and floating vegetation (Estévez et al. 2003).
