The specimens were collected at altitudes from 370 m to 2000 m. Further characteristics of sampling sites are given in Englmaier et al. (2020) . In Saudi Arabia, the species occurs in aquatic vegetation in still reaches of small to medium-sized streams with sandy substrate ( Gattolliat et al. 2018 ). Distribution. Ethiopia (Fig. 2b ), Saudi Arabia ( Gattolliat et al. 2018 ) and potentially Iran ( Tahmasebi et al. 2020 ).
