Comments. This species was collected in oligotrophic and shallow water, at various height. Most species live in springs and streams with muddy substrate or in lentic habitats with aquatic plants, but a few specimens were also collected in lotic habitats. This species was first recorded from Tunisia by Ferrari (1884).

Distribution. Palearctic region (Polhemus, 1995; Carapezza, 1997; Fent et al. 2011; Aukema et al. 2013).
