Rhogadopsis Brethes, 1913 stat. n. Figs 314-373

Rhogadopsis Brèthes, 1913: 44; Shenefelt 1975: 1212; Wharton 1987: 66(synonymy with subgenus Lissosema). Type species (by monotypy): Rhogadopsis miniacea Brèthes, 1913 [examined].

Lissosema Fischer, 1972a: 359. Type species (by original designation): Opius parvungula Thomson, 1895 [examined].

Diagnosis.

Propodeum with a medio-longitudinal carina anteriorly (Figs 317, 327, 336, 344, 352, 366); vein m-cu of fore wing gradually merging into 2-CU1 and linear with vein 2-M or nearly so; vein 1r-m of hind wing less oblique and 0.7-1.0 times as long as vein 1-M; anterior groove of metapleuron crenulate, but smooth in Rhogadopsis semiplanata; vein CU1b of fore wing medium-sized.

Biology.

Parasitoids of Agromyzidae.

Notes. Lissosema Fischer, 1972, is a junior synonym of Rhogadopsis Brèthes (Wharton, 1987), its type species has a short malar space with no distinct malar suture. Both names have been used as subgenera in the genus Opius (Fischer 1972b; Wharton 1987), but according to the molecular data and the derived wing venation this group forms a separate clade and, therefore, Rhogadopsis is elevated to generic rank.
