Sperchon clupeifer Piersig, 1896

Records ( Table 2): Benthos samples at one spring site in Gutland, 1 individual ( Gerecke et al. 2005). No larvae found in traps.

Descriptions of larvae ( Fig. 16 ): Tuzovskij (1977), Ullrich (1976), Wainstein (1980).

Diagnostic characters of larvae: In contrast to the other three Sperchon species that bear a seta C3 ( S. thienemanni Koenike, 1907 , S. longissimus K.Viets, 1920 and S. denticulatus Koenike, 1895 ), S. clupeifer has legs without lineation.
