Sympotthastia macrocera Serra-Tosio 1973

Sympotthastia macrocera Serra-Tosio, 1973 Material examined. 2 pupal exuvia, Rika River (S 6) in Soimy village, 7 May 2018. Distribution. Palaearctic. For a long time, known only from Western Europe (France, Germany; Ashe and O’Connor 2009). More recent data comes from the Drava River in Croatia (Kresonja 2018). Our record is evidence for the current easternmost occurrence in Europe, but there are indications that the distribution of this species may extend as far as the Ural Mountains (Krasheninnikov 2012). Habitat. Generally, larvae of the genus Sympotthastia inhabit cold running waters and springs (Sæther and Andersen 2013). A few data indicate that S. macrocera is probably a rheophilic species. Remarks. Sympotthastia macrocera appears to be a relatively rare species with little known ecology.
