Feltria rouxi Walter, 1907

Records (Table 2): Benthos samples at two spring sites in Gutland and in Ösling, 3 individuals (Gerecke et al. 2005). E6 1 larva, parasitic on chironomid. Attribution by cooccurrence.

Description of larvae (Figs. 42, 43): Efford (1966).

Diagnostic characters of larvae: Strong lineation of legs and Dp.

Remarks: No detailed description of Feltria rouxi exists. In the work of Efford (1966, description of the later synonymized F. ro m i j n i), no measurements were given and few drawings are presented. The present larvae almost certainly belong to a species of the genus Feltria . Since in Luxembourgian springs F. ro u x i is the only species of the genus (Gerecke et al. 2005), the Feltria individuals were attributed to this species.
