On the morphology and classification of larval water mites (Hydrachnidia, Acari) from springs in Luxembourg Author Martin, Peter text Zootaxa 2006 1138 1 44 journal article 10.5281/zenodo.172007 bd92c31d-534c-4bb2-a395-fb69e7ab01a9 1175­5326 172007 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.
