Cricotopus (Cricotopus) pallidipes Edwards 1929

Cricotopus (Cricotopus) pallidipes Edwards, 1929 Material examined. 1 pupal exuvium, Rika River (S 8), 7 May 2018. Distribution. Palaearctic. Finland, Norway, France, Portugal, Spain, Germany, Great Britain, Ireland, Romania, Hungary, Russia, Lebanon, and Morocco (Cobo et al. 2002; Soriano and Cobo 2006; Móra et al. 2006; Ashe and O’Connor 2012). Habitat. The ecological requirements of this species are still unclear. It has been found in flowing and stagnant waters in cold climatic zones (Aagaard et al. 1997; Pozdeev 2012) to warm rivers, canals, lakes, and marshes in central and southern Europe, and North Africa (e. g., Laville and Tourenq 1968; Móra et al. 2006; Abbou and Fahde 2017; Moubayed et al. 2019). French authors (Tourenq 1976; Moubayed et al. 2019) consider it a lacustrine species, tolerant of low oxygen content. Remarks. Currently known only from few European countries. It does not seem to be abundant anywhere. In Bavaria and the Sauerland Mountains (Germany), it is listed among possibly endangered species; however, its status is unknown (Orendt and Reiff 2003; Dittmar 2012).
