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 Genus Tiphys Koch, 1836 Diagnosis (for the family see above): Setae Mp1 posterior, slightly posteromedial, or posterolateral to bases of Lp1; suture line between coxal plates II–III extending to lateral apodeme; a transverse muscle attachment scar present medially at posterior end of coxal plates II–III. Setae E1 located on anterior half of plate. Descriptions of larvae ( Fig. 51 ): Many Tiphys larvae have been described, e.g. Tiphys latipes (Müller, 1776) by Smith (1976) and Wainstein (1980) . Diagnostic characters of larvae: See characters of the genus Tiphys . Remarks: The characters of the larvae and the findings from other spring surveys (e.g. Viets 1923 for lowland springs) suggest that the larva belongs to the genus Tiphys , whose species hitherto cannot be separated. In the Luxembourgian springs, no adults of Tiphys spp. have been reported ( Gerecke et al. 2005 ), but species of the genus were frequently noted from helocrenes in all parts of Europe.
