Psectrocladius (Allopsectrocladius) platypus

Psectrocladius (Allopsectrocladius) platypus (Edwards, 1929) Material examined. • 64 pupal exuviae, 1 pharate adult – male, Lake Vartopul 2 (M 4), 1 July 2024 • 1 pupal exuviae, Taul Hardau (R 3), 6 July 2023. Distribution. Palaearctic. Known from several European countries, as well as Turkey and Algeria (Ashe and O’Connor 2009). Habitat. The species is typical of small, acidic, stagnant waters in moorlands and peat bogs. In addition to tolerating low pH, it can withstand low oxygen levels in polyhumic waters; however, larvae are also found in lake littorals and small streams with slow currents (Moller Pillot 2013 and references therein). In the Western Carpathians, pupal exuviae were collected from a small, non-acid sub-alpine lake (Bitušík et al. 2006). The species is frequently recorded in temporary pools and ponds (e. g., Bazzanti et al. 1997; Puntí et al. 2007), as well as ephemeral waters (Moller Pillot 2003), indicating relatively high dispersal potential of females. Remarks. The findings indicate the humic conditions of Taul Hardau and suggest at least partial drying of Lake Vartopul 2.
