Eurytoma View in CoL View at ENA belonging to the robusta species group

The group, here considered in its restricted sense ( Lotfalizadeh et al. 2007), can be diagnosed as follows: gena margined posteriorly by raised carina ( Figs 22C View FIGURES 22 , 25D View FIGURES 25 ); back of head with raised postgenal lamina visible even in lateral view and with ventral postgenal depression ( Fig. 22C View FIGURES 22 ); lower face with radiating carinae reaching up to the antennal toruli, interantennal space not projecting ( Figs 22A View FIGURES 22 , 25A View FIGURES 25 ), ventral belt of prepectus with sharp median tooth ( Figs 22D View FIGURES 22 , 24 View FIGURE 24 ); mesepisternum with completely delimited epicnemium and ventral shelf ( Fig. 24 View FIGURE 24 ); propodeum with wide mesal depression with irregular sculpture ( Fig. 22E View FIGURES 22 ); procoxa with oblique depression on anterior side not delimited laterally by carina ( Fig. 22F View FIGURES 22 ); metacoxa basidorsally bare ( Fig. 24 View FIGURE 24 ); gaster subpetiolate with petiole bearing two small anterolateral teeth and a mediodorsal tooth ( Fig. 24 View FIGURE 24 ).

The pair of Eurytoma species associated with asphodels may be separated from the remaining species belonging to the robusta group especially by the aspect of the notauli. The group may be split in two sets, also according to the habitus of the notauli. In the first set, to which belongs E. strigifrons Thomson, 1876 , the notauli are narrow but distinctly impressed with a smooth bottom and step-like margins; in the second set, which especially includes E. robusta Mayr, 1878 and E. inulae Domenichini, 2002 , the notauli are conversely shallow, obliterated by the sculpture of the mesonotum, and with poorly defined lateral margins. In the two Eurytoma associated with asphodels, the notauli show another state: they are also well impressed but partly obliterated by the sculpture of the mesonotum and with blunt lateral margins ( Fig. 25D View FIGURES 25 ).
