Material examined.

• 26 pupal exuviae, Lake Buhaescu 2 (R 10), 5 July 2023 • 22 pupal exuviae, Lake Buhaescu 3 (R 11), 5 July 2023 .

Distribution.

Palaearctic. Widespread in Europe including the Canary Islands ( Langton and Visser 2003); also recorded in Morocco ( Kettani and Langton 2011).

Habitat.

Traditionally, the species is considered cold stenothermic and polyoxybiontic ( Säwedal 1976). It has been documented in mountain, boreal and woodland springs and spring brooks ( Orendt 2000; Ilmonen et al. 2009; Lencioni et al. 2012), as well as alpine lakes and ponds ( Bitušík et al. 2006; Oertli et al. 2010; Lods-Crozet et al. 2012). However, data from low-altitude streams suggest a wider temperature tolerance ( Móra and Szivák 2012). Its presence in temporary habitats, such as fountains ( Oboňa et al. 2017) and temporarily flooded wetlands ( Lundström et al. 2010), indicates a high distribution potential of females.

Remarks.

The presence of M. notescens in Romania has already been reported by Säwedal (1976) based on two males collected by Andrzej Kownacki from the Fagaras Mts. However, the species is not listed in the latest checklist of Romanian Chironomidae ( Tatole 2023).
