Revision of the genus Halys (Hemiptera: Pentatomidae) with description of a new species from India

Abstract

The species of the genus Halys Fabricius, 1803 (Hemiptera: Heteroptera: Pentatomidae: Pentatominae: Halyini) from India are redescribed and revised. Examination of more than 300 specimens collected from all over the country revealed the presence of four species, including a new species: Halys mudigerensis sp. nov., H. serrigera Westwood, 1837, H. shaista Ghauri, 1988 and H. sulcata (Thunberg, 1783). The following synonymies are proposed: H. sulcata (Thunberg, 1783) = Halys sindillus Memon, Meier & Manan, 2006, syn. nov. = Halys spinosus Shaikh, Memon & Shah, 2011, syn. nov. = Halys mulberriensis Memon, Parveen, Ahmad & Shaikh, 2016, syn. nov. = Halys noakoatensis Memon, Parveen, Ahmad & Shah, 2017, syn. nov.; H. serrigera Westwood, 1837 = Halys fabricii Memon, Ahmad & Perveen, 2002. Halys neelgiriensis, Halys rugosa and Halys persa are considered as incertae sedis. The diagnostic characters of species of Halys are compared and keys to males and females of Halys species occurring in India are provided.
