Hexarhopalus Fairmaire 1891

List of the species of the genus Hexarhopalus Fairmaire, 1891 Remark. Masumoto & Akita (2022) described Hexarhopalus maoi Masumoto & Akita, 2022 from Laos. According to the description and the photo of habitus provided in their paper I have strong doubts that this species belongs to genus Hexarhopalus due to lacking claviform femorae (present in all known species) and indentation in posterior angles of pronotum which can be quite weakly developed and thus is inconspicuous but always obvious.
