Remarks. A very distinctive species, belonging to the caesia -group of Lispe (Hennig 1960) . It can be identified with the key by Hennig (1960) to Palaearctic Lispe . It is very similar to Lispe caesia Meigen, 1826 and the characters distinguishing the two species have been given in a key by Vikhrev et al. (2016) who also illustrate the male terminalia ( Vikhrev et al. 2016, figs 8–9).
