Diagnosis: Volkelius belongs to the Odoniella -complex and is recognized by the following characters: ASII incrassate towards apex (as in Fig. 8E ); ASIII–IV distinctly clavate (as in fig. 8F in Namyatova et al., in press); pronotum and scutellum impunctate, with longitudinal and shallow wrinkles ( Figs 10H , 12A ); scutellum only moderately swollen, not vesiculate; tooth on claw long (fig. 3F, I in Namyatova & Cassis, 2014); DLP with sclerotized circle and spermathecal gland placed on right-hand side (fig. 5 in Namyatova & Cassis, 2014).

Description: See Namyatova & Cassis (2014).

Distribution: Known from Australia ( Fig. 24 ).

Host plants: Volkelius carvalhoi was collected from Tephrosia sp. aff. rosea ( Papilionaceae ). Volkelius maculatus was collected from Ficus rubiginosa (Moraceae) ( Namyatova & Cassis, 2014).
