Miridae, commonly plant bugs, is the most diverse group in Heteroptera, with more than 11,000 species, and is widely distributed in the world. This group has a great attention by taxonomists, applied entomologists, and evolutionary biologists because of their great morphological diversity, high biodiversity as well as association with host plants. However, there have been a few phylogenetic studies within this family to date. In this talk, we present the first phylogenetic analyses of the largest tribe Mirini in the family Miridae based on nuclear (18S rRNA and 28S rRNA) and mitochondrial (COI and 16S rRNA) sequence data, based on the results, we discuss on the phylogenetic relationships and classifications within the tribe.
