Pediobius epigonus species group

Diagnosis. Scutellum at least anteriorly densely longitudinally reticulate, meshes often indistinctly elongate. Female antenna with three funicular segments not clearly separated from clava, which seems funicle 2-segmented and clava 3-segmented (e.g., Fig. 9 g). Male antenna filiform, never with a differentiated clava (e.g., Fig. 9 f). Scrobal grooves in female always meeting below the frontofacial sutures.

Species included. Bouček (1965a) included P. eubius complex and P. metallicus in the epigonus -group, but also divided this group into two subgroups, the eubius- subgroup and the epigonus -subgroup. The eubius- subgroup includes P. eubius complex, P. nigritarsis (Thomson) and P. polanensis Bouček (Bouček 1965a) . The epigonus - subgroup includes P. epigonus (Walker) , P. glabratus Bouček , P. metallicus , P. oviventris Bouček (Bouček 1965a) and also those species described by Dawah (1988) and Dawah et al. (2002). Hansson (2006) included a distinct species, P. sasae Hansson , in the eubius -group. We follow Bouček (1965a) and include them in the epigonus -group despite the possibilities of different separation for its members. Besides, we add a newly described species, P. prominentis , which seems closer to P. eubius .
