Zavrelimyia punctatissima (Goetghebuer, 1934) View in CoL

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 .
