Diagnosis.

Fidiobia vladlubomiri is a distinct species that can be recognized by wide, deeply incised notauli with the lateral margins located medial to the axillular carina, meeting the scutoscutellar sulcus. The transepisternal line is nearly complete and sigmoid in shape. The dorsal mesopleural area has some transverse striae, and between these striae and the transepisternal line there is a large unsculptured area (in F. striatitergitis and F. nipponica this area is transversely striate). The dorsal metapleural area is covered with dense silvery setae that easily distinguish F. vladlubomiri from F. striatitergitis and F. nipponica . The papillary sensillum located at the apex of the distal clavomere (Fig. 277b ) makes F. vladlubomiri unique among the known Palaearctic species of Fidiobia .
