Genus Halys Fabricius, 1803

Ghauri (1988: 78) removed all species from this genus except four, but he did not mention most species by name, nor did he indicate to which genera they belong. Of the species listed below, he retained only serrigerus and sulcatus in Halys. The remaining species apparently belong in other genera, but are still listed here until their true taxonomic status can be determined. Doyère (1837: pl. 88) designated Cimex mucoreus Fabricius, 1794, the type species of Erthesina Spinola, 1837, as the type species of Halys. The ICZN should be asked to set aside this designation in order to provide stability of the generic names,
