Procladius (Holotanypus) simplicistilus Freeman 1948

Procladius (Holotanypus) simplicistilus Freeman, 1948 Material examined. • 1 pharate adult – male, Lake Gargalau 3 (R 5), 6 July 2023. Distribution. Palaearctic. The species was recorded only from a few countries in West and North Europe, but also from the Far East of Russia (Ashe and O’Connor 2009). Habitat. The ecological requirements of this species are not sufficiently known because of the problematic identification of the pre-imaginal stages. Generally, larvae inhabit stagnant waters, they are resistant to low pH values (Murray and Baars 2006; Perova 2008; Baars et al. 2014) and salinity (Kawai et al. 2000). Remarks. An adult male with associated exuviae confirms the presence of the species in Romania.
