The classification of the hyperdiverse true bug family Miridae is far from settled, and is particularly contentious for the cosmopolitan subfamily Bryocorinae. The morphological diversity within the subfamily is pronounced, and a lack of explicit character formulation hampers stability in the classification. Molecular partitions are few and only a handful of taxa have been sequenced. In this study the phylogeny of the subfamily Bryocorinae has been analysed based on morphological data alone, with an emphasis on evaluating the tribe Dicyphina sensu Schuh, 1976, within which distinct groups of taxa exist. A broad sample of taxa was examined from each of the bryocorine tribes. A broad range of outgroup taxa from most of the other mirid subfamilies was also examined to test for bryocorine monophyly, ingroup relationships and to determine character polarity. In total a matrix comprising 44 ingroup, 15 outgroup taxa and 111 morphological characters was constructed. The phylogenetic analysis resulted in a monophylet
