Zavrelimyia punctatissima (Goetghebuer, 1934)

Material examined.

• 6 pupal exuviae, Taul Stiol (R 4), 3 July 2023 .

Distribution.

West Palaearctic. The species is known from a few European countries: Austria, France, Germany, Italy, Norway, and Slovakia ( Ashe and O’Connor 2009).

Habitat.

It is a cold-stenothermal species adapted to live in oligotrophic waters with high oxygen concentrations ( Boggero and Lencioni 2006). Boggero (2018) considers it strictly rheophilous. The species is a typical inhabitant of the littoral, inlets and outlets of alpine lakes ( Rossaro et al. 2006; Hamerlík and Bitušík 2008; Steingruber et al 2013).

Remarks.

Pupal exuviae closely resemble those of Zavrelimyia hirtimana (Kieffer, 1918) , but all collected specimens exhibit very small plastron plates. The plastron plate diameter to thoracic horn length (0.054 –0.055) aligns with the diagnosis of Langton and Visser (2003) for Z. punctatissima .
