Abstract

Species of the genus Colocasiomyia de Meijere feed/breed on inflorescences/infructescences of the plants from the families Araceae, Arecaceae and Magnoliaceae. Although most of them utilize plants from the subfamily Aroideae of Araceae, three species of the recently established C. gigantea species group make use of plants of the subfamily Monsteroideae. We describe four new species of the gigantea group found from Yunnan, China: Colocasiomyia longifilamentata Li & Gao, sp. n., C. longivalva Li & Gao, sp. n., C. hailini Li & Gao, sp. n., and C. yini Li & Gao, sp. n. The species delimitation is proved in virtue of not only morphology but also DNA barcodes, i.e., sequences of the partial mitochondrial COI (cytochrome c oxidase subunit I) gene. Some nucleotide sites with fixed status in the alignment of the COI sequences (658 sites in length) are used as “pure” molecular diagnostic characters to delineate species in the gigantea group.
