General distribution. Brazil, Paraguay, Argentina ( Herrera 2013).

Habitat. Little information exists regarding the habitat associations of C. schadei . It has been collected in densely vegetated lagoons, marshlands and rivers ( López Ruf 1988, 2004; Estévez et al. 2003; Torres et al. 2007).

At the INR, specimens were collected from the margins of the Iberá Lagoon in shallow waters with emergent and floating vegetation (Estévez et al. 2003) and in Iberá in association with Cabomba caroliniana , Salvinia sp. , Pontederia crassipes , Nymphaea sp. and Lemnaceae ( Poi de Neiff 1993; López Ruf 2004). During the present study, it was collected from unshaded margins with dense floating, emergent and submerged vegetation (mainly Pontederia crassipes , Myriophyllum aquaticum , Nymphoides indica and Salvinia biloba ) in lentic habitats (ponds, Luna Lagoon, Galarza Lagoon, Medina Lagoon and ditches), and lotic habitats (Vizcaychipi channel and Isirí Stream) in standing or slow-moving water.

Remarks. This species was recorded from the Iberá Lagoon by López Ruf (2004).
