Gumovsky, Alex, 2021, Review of the species of Pediobius (Hymenoptera, Eulophidae) having extreme dorsal setation and description of a new species from East Africa, Zootaxa 4999 (5), pp. 423-438 : 424

setigerus species group (new)

Diagnosis. Mesoscutum and/or mesoscutellum with strong, spiky bristles ( Figs 1–7 ), anteromedial margin of mesoscutellum with a notch: small ( P. setigerus and P. multisetis , Figs 3B , 5 ) or deep and bordered by tooth-like projections ( P. erinaceus , Figs 6C , 7B ); antenna with F3 broadly attached to first claval segment, so the funicle is functionally 2-segmented and the clava is functionally 3-segmented ( Fig. 4 ).

Additionally, head wider than mesosoma, faintly sculptured to smooth, with distinct X-shaped frontal sutures ( Figs 2E , 4D ); lower face moderately narrowed, antennae inserted somewhat below or at the level of lower eye margins ( Fig. 2E ); sculpture of dorsum faint to alutaceous.

Species included. Pediobius setigerus , P. multisetis , P. sp. aff. multisetis , and P. erinaceus sp. n.
