Panisus michaeli Koenike, 1896

Records ( Table 2): Benthos samples from three springs in Ösling, 2 individuals ( Gerecke et al. 2005). No larvae found in traps.

Descriptions of larvae ( Figs. 2, 3 ): Lundblad (1927), Martin (2003).

Diagnostic characters of larvae: The setation of the Expp (only one pair of setae) and of the leg segments I­L3 and II­L3 enables a separation of P. michaeli larvae from the other Hydryphantidae known from Luxembourg springs.
