Trichoxys cinereolus was originally described by Bates (1892) in the genus Trichoxys , and subsequently transferred to Tanyochraethes by Chemsak & Linsley (1965). On the other hand, O. octomaculata was originally described by Chemsak & Noguera (2001). The characters that support this synonymy are the frons transverse ( Fig. 4C–D ), the elytral apex oblique-truncate, the mesoventral process moderate elevated; even the pattern of the pubescence on the elytra is the same. This pattern of pubescence on the elytra is similar in Tanyochraethes anthophilus ( Chevrolat, 1860) , T. clathratus ( Chevrolat, 1860) , and T. tildeni Chemsak & Linsley, 1965 . However, the shape of the frons and vertex is totally different. Accordingly, we consider O. octomaculata as a junior synonym of T. cinereolus . We used characters of the type specimens of both species to stablish the new combination for Ochraethes cinereolus .
