Revision of Acesines Stål and Dunnius Distant, resurrection of Mycterizon Breddin (Hemiptera, Heteroptera, Pentatomidae, Pentatominae), and description of a new species from India.

The genera Acesines Stål, 1876 and Dunnius Distant, 1902 (Hemiptera: Heteroptera: Pentatomidae: Pentatominae) were revised and redescribed with the description of Dunniusbarpetensis Salini & Rabbani, sp. nov., based on specimens from Assam and Meghalaya, northeastern states of India. The genus Mycterizon Breddin, 1909 is reinstated from Dunnius, removed from the tribe Menidini, and redescribed. Consequently, the following new combinations are proposed: A.sordida (Kirby, 1891), comb. nov., Dunniuslaticeps (Zheng & Liu, 1987), comb. nov., D.tridentatus (Xiong & Liu, 1995), comb. nov., and D.trifasciatus (Xiong & Liu, 1995), comb. nov. A lectotype is designated for Araductabella (Distant, 1900a). Acesinesbambusana Distant, 1918, and Mycterizonbellusstat. rev. are redescribed based on both male and female genitalia and Dunniusfulvescens (Dallas, 1851) is redescribed based on female genitalia.
