The plant bug family Miridae is the largest group in Heteroptera, and is one of the most important insect groups economically in agriculture and in forestry, because it contains insect pests and predators. Among the subfamilies, Deraeocorinae represents the predatory group including some members which can be used as a biological control agent. This group comprises a total of six tribes in whole regions with their own unique morphology. However, the monophylies and relationships of tribes and genera within this subfamily are not still explored phylogenetically. In this talk, the first phylogenetic analyses of Deraeocorinae are presented based on total evidence data. Major questions including monophylies and relationships of each taxa on the basis of the results are discussed.
