Reassessment of the moth genus Bacotoma, with a new species from Hainan Island (Lepidoptera: Crambidae: Spilomelinae)
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.
