Abstract

Metreletus omelkoi sp. nov. (male, female imagines and male, female subimagines, larvae and egg) is described from the fareastern region of Russia. The genus Metreletus Demoulin, 1951 has a trans-Palaearctic distribution and includes two species:the West-European mountain species, M. balcanicus Ulmer, 1920, and the Far-Eastern species, M. micus Bajkova, 1976. Metre-letus omelkoi sp. nov. is the second species from Far-Eastern Russia and the third globally. The larvae of M. omelkoi sp. nov.differ from the other species in their genus by the size of gill I (M. micus) and the form of gills II–VII (M. balcanicus). The male imago of the new species can be distinguished from M. balcanicus by shape, the penis lobes.
