Mideopsis willmanni (K.Viets, 1920)

Records ( Table 2): Benthos samples at three spring sites in Gutland and in Ösling, 5 individuals ( Gerecke et al. 2005). E4 1 larva, parasitic on a chironomid. Attribution by comparison with Viets (1928) and Smith (1978).

Descriptions of larvae ( Figs. 55, 56 ): Viets (1928).

Diagnostic characters of larvae: As given for the genus.

Remarks: The state of the single specimen was too poor for a description of the species. However, since the crenobiontic Mideopsis willmanni is the only species of the genus in the Luxembourgian springs ( Gerecke et al. 2005), the assignment of the specimen to M. willmanni seems to be certain.
