Orthocladius (Orthocladius) rivinus Potthast, 1914

Material examined.

1 pupal exuvium, left-hand tributary of Zhdenivka River (S 3), 7 May 2018 .

Distribution.

Palaearctic. Norway, Great Britain, Ireland, Austria, Slovakia, Hungary, Poland, Belarus, Germany, Switzerland, France, Italy, Spain, Canary Islands, and Portugal ( Cobo et al. 2002; Ashe and O’Connor 2012; Moller Pillot 2013; Móra et al. 2013; Sołtys-Lelek et al. 2014).

Habitat.

Rheophilic species inhabiting springs and flowing waters from small streams to large rivers, although it has been reported also from lakes ( Langton and Visser 2003). Rossaro et al. (2003) underline its preference for cold waters, but some findings question this (e. g., Langton and Orendt 1996; Móra et al. 2013).

Remarks.

The species is known from a few European countries and is generally considered rare. Like the ambiguous data on its ecology, this may also be the result of misidentification.
