Synendotendipes lepidus

Synendotendipes lepidus (Meigen, 1830) Material examined. • 4 males, 1 female, Lake Gargalau 3 (R 5), 6 July 2023. Distribution. Palaearctic. Widespread in Europe (Ashe and Cranston 1984, Moller Pillot 2009), and it has been reported from Turkey (Ozbek et al. 2018) and the Russian Far East (Orel 2016). Habitat. The species has been recorded mainly from stagnant waters regardless of size and trophic status. Lundström et al. (2010) collected adults from temporary wetlands, and there are data from lowland brooks (Ozbek et al. 2018). Like other species of the genus, it tolerates acid conditions of peatland pools (Plóciennik et al. 2018). According to Moller Pillot (2009), the larvae are miners in the tissues of Nuphar lutea. However, they evidently utilize other types of littoral vegetation, such as sedges, since N. lutea does not occur in the studied lakes. Remarks. Species of the genus Synendotendipes are indistinguishable as pupal exuviae, so it is not possible to confirm if Synendotendipes pupal exuviae recorded in other lakes also belong to S. lepidus.
