Abstract
A cladistic analysis of the tribe Bryocorini based on 68 morphological characters is conducted. Bryocorini are supported as a monophyletic group with Eccritotarsini as their sister taxon. Based on the phylogenetic analysis, we redefine the tribe Bryocorini to contain the following seven genera: BryocorellaCarvalho, 1956, BryocorisFallén, 1829, BryophilocapsusYasunaga, 2000, CobalorrhynchusReuter, 1906 gen. dist., Diplazicoris gen. nov., HekistaKirkaldy, 1902, and MonalocorisDahlbom, 1851. The genus Bryocorella is transferred to Bryocorini from the tribe Eccritotarsini. The subgenus Cobalorrhynchus is treated as a separate genus. Diplazicoris is described as monotypic to accommodate Diplazicoris lombokianus sp. nov An updated diagnosis of the tribe, a key to genera, and a diagnosis of each recognized genus are presented. Selected photomicrographs, scanning micrographs, and illustrations of the pretarsus, metepisternal scent efferent system, metafemoral trichobothria, and morphology of head, pronotum, and male and female genitalia are provided. Mapping of the host data on the revealed tree shows that Bryocorini represent one of the very few currently known examples of the adaptive radiation of a fairly large insect group on ferns.
