最近对多栖食草昆虫的DNA条形码研究发现，在已命名的物种中存在着隐种复合体。根据寄主植物记录和线粒体细胞色素c氧化酶I单倍型多样性，对新几内亚和澳大利亚常见的一种多面手蛾（Homona mermerodes）的物种概念进行了评估。不同寄主树种间的遗传差异远低于同一种间的遗传差异。新几内亚和澳大利亚单倍型之间的遗传差异也小于种间差异。虽然分子物种鉴定方法可能在一些多面体食草动物中发现隐种，但当从多个寄主植物科中培养出相同的单倍型时，这些方法也可能证实多食。本文为该种指定了一种类型，并首次提供了包括雄性生殖器在内的摘要参考书目和插图。
Recent DNA barcoding of generalist insect herbivores has revealed complexes of cryptic species within named species. We evaluated the species concept for a common generalist moth occurring in New Guinea and Australia, Homona mermerodes, in light of host plant records and mitochondrial cytochrome c oxidase I haplotype diversity. Genetic divergence among H. mermerodes moths feeding on different host tree species was much lower than among several Homona species. Genetic divergence between haplotypes from New Guinea and Australia was also less than interspecific divergence. Whereas molecular species identification methods may reveal cryptic species in some generalist herbivores, these same methods may confirm polyphagy when identical haplotypes are reared from multiple host plant families. A lectotype for the species is designated, and a summarized bibliography and illustrations including male genitalia are provided for the first time.
