Euodynerus (Pareuodynerus) bidentoides ( Giordani Soika, 1953) , sp. resurr.

( Figs 11B, C, E–G ; 14K ; 15B, V )

Odynerus bidentoides Giordani Soika, 1953: 250 , ♀ (in subgenus Euodynerus ) — [ Morocco] “ Midelt ” (? type lost).

Distribution. The Maghreb and the Iberian Peninsula ( Gusenleitner 1997).

Notes. Gusenleitner (2013) synonymized E. bidentoides under E. bidentiformis without providing any information supporting this taxonomic action. Our data clearly show that the two taxa are similar but still welldifferentiated species ( Fig. 10 ), with an average genetic distance of 38.94% confirming the diagnostic value of the morphological characters provided by Giordani Soika (1953) and Gusenleitner (1997).

Numbers adjacent to branches represent bootstrap support (values of <75 are omitted); only the species occurring in the considered area are highlighted. Countries are abbreviated using ISO 3166-1 alpha-2 codes.
