Bacotoma Moore, 1885 is reviewed including the description of a new species from Hainan Island, B. hainanensis sp. nov. , based on an analysis that combined morphology and mitochondrial DNA. The following taxonomic changes are proposed: Platamonina Shaffer & Munroe, 2007 , syn. nov. is synonymized with Bacotoma and ten species are included: B. ampliatalis (Lederer, 1863) comb. nov. , B. binotalis (Warren, 1896) comb. nov. , B. camillusalis (Walker, 1859), B. cuprealis (Moore, 1877) comb. nov. , B. hainanensis sp. nov. , B. illatalis (Walker, 1866), B. oggalis (Swinhoe, 1906) comb. nov. , B. poecilura (Hering, 1903) comb. nov. , B. ptochura (Meyrick, 1894) comb. nov., and B. violata (Fabricius, 1787). Syngamia albiceps Hampson, 1912 syn. nov. is confirmed to be a synonym of Bacotoma binotalis , and Platamonia medinalis Snellen, 1900 syn. nov. is synonymized with Bacotoma illatalis. A key to species examined is also provided based on external morphology and male genitalia. [ABSTRACT FROM AUTHOR]
