Thyas palustris Koenike, 1912

Records (Table 2): Benthos samples at four springs in Gutland and in Ösling, 9 individuals (Gerecke et al. 2005). E1 17 larvae, E3 67 larvae, parasitic on Limoniidae . Attribution by comparison with Martin (2003).

Description of larvae (Figs. 2, 3): Martin (2003).

Diagnostic characters of larvae: In contrast to the other Hydryphantidae reported here relatively small in dimensions (e.g. length of idiosoma, leg, chelicera).

Remarks: The taxonomic state of T. rivalis Koenike, 1912, proposed as a synonym of T. palustris by Lundblad (1962), is still an unsolved problem (Gerecke, pers. comm.). The larval description of Biesiadka & Cichocka (1990) for T. rivalis does not include details that enable a separation from T. palustris .
