Figs 7–11

Type species: Myriola gussakovskii Shestakov, 1932 .

Diagnosis. Antenna of female slender submedially, with 20 antennomeres; eyes often glabrous or short setose ( Figs 9C , 11C & K ); maxillary palp with 5 segments; clypeus almost as wide as face ( Figs 7B , 9B , 11C & K ); prepectal carina absent ( Figs 7F , 10A & B , 11I ); medial areola of dorsal face of propodeum narrow ( Figs 8B , 10C & D , 11D ); vein 1-R1 of fore wing completely absent ( Figs 7A , 9A , 10E , 11A ); vein 1-SR of fore wing distinct and slender; second metasomal tergite usually smooth ( Figs 8B , 10D , 11D ); metasomal sutures absent or shallowly impressed and smooth ( Figs 8B , 10D , 11D ).

Distribution. East Palaearctic.

Included species. Myriola aridus Tobias, 1967 , M. ferulae Tobias, 1964 , M. gussakovskii Shestakov, 1932 , M. magna Tobias, 1967 .

Notes. Myriola Shestakov, 1932 , is traditionally included in Adelius Haliday, 1833 ( Yu et al. 2016), but there are several differences between both taxa as listed above in the key to genera. Therefore, we re-instate Myriola as a valid genus.
