Sperchonopsis verrucosa (Protz, 1896)

Records (Table 2): Benthos samples at two spring sites in Gutland, 9 individuals (Gerecke et al. 2005). E7 22 larvae, parasitic on chironomids. Attribution by comparison with Martin (2000).

Descriptions of larvae (Fig. 15): Protz (1896), Martin (2000).

Diagnostic characters of larvae: As in Sperchon setiger Thor, 1898 and S. insignis (Walter, 1906) (see below), and in contrast to the other Sperchontidae larvae reported here, the larva of Sperchonopsis verrucosa lacks setae C3. The larva of Sperchonopsis verrucosa differs from that of Sperchon insignis in, for example, their larger dorsal plate and short seta C4.
