Phylogeny and systematics of the subfamily Bryocorinae based on morphology with emphasis on the tribe Dicyphini sensu Schuh,

The classification of the hyperdiverse true bug family M iridae is far from settled, and is particularly contentious for the cosmopolitan subfamily B ryocorinae. 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 B ryocorinae has been analysed based on morphological data alone, with an emphasis on evaluating the tribe D icyphina sensu S chuh, 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 monophyletic subfamily B ryocorinae sensu S chuh (1976, 1995), except for the genus Palaucoris , which is nested within C ylapinae. The tribe D icyphini sensu S chuh (1976, 1995) has been rejected. The subtribe O doniellina is synonymized with the subtribe M onaloniina and the subtribes D icyphina, M onaloniina and E ccritotarsina are now elevated to tribal level, with the D icyphini now restricted in composition and definition. The genus Felisacus is highly autapomorphic and a new tribe – the F elisacini – is erected for the included taxa. This phylogeny of the tribes of the B ryocorinae comprises the following sister‐group relationships: D icyphini (( B ryocorini + E ccritotarsini)( F elisicini + M onaloniini)).
