Treatment

Smittia Holmgren View in CoL / Parasmittia Strenzke ( Figs 64, 65 View FIGURES 60–65 )

Head capsule yellow to brownish, occipital margin pale or darkened. Antenna reduced, with 4 segments. Blade well developed and as long as flagellum ( Smittia , Fig. 65A View FIGURES 60–65 ) or considerably longer ( Parasmittia ). Premadible with 2 apical teeth and 1 variably developed inner tooth. Mandible with 3 inner teeth and short apical tooth. Mentum with one broad median tooth with projecting nipple (may be domed in Smittia ) and 5 pairs of subequal lateral teeth. Ventromental plates well developed, not extending outermost teeth.

Remarks: Smittia and Parasmittia are indistinguishable in specimens with missing antennae.

In the Tatras, only Smittia edwardsi Goetghebuer, 1932 was determined based on adults ( Bitušík 2004).

Remains of Smittia / Parasmittia were recorded infrequently in the studied lakes. As mentioned above (see Limnophyes / Paralimnophyes ), presence of subfossils of semiterrestrial/ terrestrial taxa such as Smittia / Parasmittia could have indicative value in the reconstruction of water-level oscillation.
