Hygrobates norvegicus (Thor, 1897)

Records ( Table 2): Benthos samples at four spring sites in Gutland and in Ösling, 12 individuals ( Gerecke et al. 2005). E3 88 larvae, E6 1 larva, parasitic on chironomids. Attribution by comparison with Martin (2003).

Descriptions of larvae ( Fig. 41 ): Walter (1922b), Viets (1923), Ullrich (1976), Martin (2003). Larvae of Hygrobates norvegicus (see Fig. 41 ) were found as chironomid parasites in the emergence traps.

Diagnostic characters of larvae: See characters of the genus. Martin (2003) pointed out that the characteristic distal notch on the Expp of H. norvegicus is absent in other described Hygrobates larvae.
