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.
