A revision of the Solomonius-group of the stinkbug tribe Halyini (Hemiptera: Pentatomidae: Pentatominae)

The Solomonius-group is a well-defined group of genera nested within the pentatomine tribe Halyini. The group contains 31 species, 20 of which are new to science. Species are classified into seven genera: Anchises Stal, Auxentius Horvath, Babylas Horvath, Brizica Walker, Elemana Distant, Epitoxicoris gen. nov., and Solomonius gen. nov. The genus Neoptolemus Horvath syn. nov. is synonymized with Brizica Walker. All species are described or redescribed and illustrated. Identification keys to all genera and species are provided. New species recognized are: Auxentius clandestinus sp. nov., Au. nigriculus sp. nov., Au. quasimodooides sp. nov., Au. vulgaris sp. nov. Au. zephyrius sp. nov., Brizica flyensis sp. nov., Br. sphaeroides sp. nov., Br. tubercularis sp. nov., Br. vandoesburgi sp. nov., Epitoxicoris allisonae sp. nov., Ep. trimaculatus sp. nov., Solomonius browni sp. nov., S. grossi sp. nov., S. laminaphallicus sp. nov., S. lestoni sp. nov., S. malaitaensis sp. nov., S. micrometallicus sp. nov., S. rideri sp. nov., S. schaeferi sp. nov., and S. viatorius sp. nov. Neoptolemus assimilis Horvath syn. nov. is synonymized with Br. proximus (Schouteden). The following new combinations are proposed within the Solomonius-group: Brizica exiguus (Distant) comb. nov., Br. humeralis (Horvath) comb. nov., Br. proximus (Schouteden) comb. nov., Solomonius foetidus (Signoret, 1861) comb. nov., S. ornatula (Distant) comb. nov., and S. viridula (Distant) comb. nov. A lectotype is designated for Solomonius foetidus (Signoret, 1861). One species is transferred out of the Solomonius-group of genera, resulting in a new combination, Baracellus distinctus (Schoutedon) comb. nov.
