The discovery of a remarkable new palm bug species on Norfolk Island brings into question its systematic position within the family Thaumastocoridae, and the validity and biogeography of the three extant subfamilies. Latebracoris norfolcensis gen. nov., sp. nov. is described from remote Norfolk Island in the Southwest Pacific. The species was found on the native Norfolk Island palm Rhopalostylis baueri. The formal description of the species includes fine details of external non-genitalic and genitalic characters, supported with images from light and scanning electron microscopy. Details of the egg are described, including the shape and micropylar configuration. All nymphal stages are diagnosed morphologically and morphometrically, with the segregation of the five instars using the Brooks–Dyar Rule. The natural history of the Norfolk Island Palm Bug is documented, including the oviposition site of eggs, and microhabitat of nymphs and adults on palm infructescences, with hypotheses about development in relation to reproductive succession of the palm host. The systematic position of the Norfolk Island Palm Bug is assessed through a phylogenetic analysis of a selection of taxa of the superfamily Miroidea, using the parsimony criterion. The phylogenetic analyses were partitioned into Recent and fossil taxa, revealing monophyly of the Thaumastocoridae, and the subfamilies Thaumastocorinae and Xylastodorinae, with synapomorphy and significant resampling support. The Thaicorinae are verified as synonymous with the Xylastodorinae. The monotypic fossil subfamily Thaumastotinginae is removed from the Thaumastocoridae and treated as incertae familiae. Suprageneric relationships were corroborated in the two taxon partition analyses. An overview of host associations is given verifying palm specialism for the Xylastodorinae. The natural history, palm specialism, biogeography, morphology and systematics of the Xylastodorinae and allies are discussed in light of the discovery of Latebracoris norfolcensis.

Wing polymorphism and asymmetric male genitalia are intriguing morphological phenomena occurring in insects. Among Emesinae, or thread‐legged bugs, the tribe Metapterini Stål exhibits these two interesting morphological attributes. Nonetheless, evolutionary interpretations of these phenomena cannot be put forward because phylogenetic hypotheses for Emesinae are lacking. Thread‐legged bugs are easily recognized among assassin bugs due to their elongated and seemingly delicate body. The tribe Metapterini has 28 genera and approximately 280 described species. The only available phylogenetic hypothesis among Emesinae tribes was proposed by Wygodzinsky (1966), and it hypothesized Deliastini Villiers as the sister group of Metapterini, although this hypothesis has never been tested with cladistic approaches. Recent analyses using character sets of genitalia and prolegs suggest that Metapterini might not be monophyletic. In order to test these ideas, we compiled a morphological dataset of 138 characters that includes external morphological characters, detailed features of prolegs and genitalia of both sexes for Metapterini, which were analysed cladistically including 55 terminals, comprising 24 genera (85.7% of the generic diversity), 43 species of Metapterini and 12 outgroups. Metapterini was recovered as paraphyletic by the inclusion of Bergemesa Wygodzinsky, Palacus Dohrn and Stalemesa Wygodzinsky, all currently assigned to Deliastini. Gardena Dohrn (Emesini) was recovered as the sister group of Metapterini + Deliastini as suggested by Wygodzinsky (1966). Based on these results, we synonymize Deliastini syn. n. with Metapterini sensu n. and propose two new genera: Bacata Castro‐Huertas & Forero gen. n., for three Andean species previously placed in Liaghinella Wygodzinsky, and Valkyriella Castro‐Huertas & Forero gen. n. for Ghilianella borgmeieri Wygodzinsky. Ancestral state reconstruction of wing polymorphism indicates that males and females were fully winged in the ancestor of Metapterini sensu n. with two independent evolutionary transitions to the apterous and brachypterous conditions. The analysis of the symmetry of the male genitalia shows an ancestor with symmetric male genitalia and two independent emergences of asymmetrical male genitalia in Metapterini.
