Hello, this specimens was collected with Malaise trap on the Black Sea coast, in Romania, in October 2022. I think it is Camarota sp, maybe C. curvipennis (this is the only species of Camarota from Europe, am I right?)

Chloropidae, Chloropinae, Camarota curvipennis (Latreille, 1805) as the single Palaearctic species is correct; aristae are broken off in the images. A revision of the genus was published 2018 by Riccardi & von Tschirnhaus in Zootaxa 4526(2): 221-231. In this forum already seven further links are available for C. curvipennis.
