. The rhyparochromine lygaeid genus Pseudopachybrachius is revised. Four species are recognized in the perplexing vinctus‐gvoup (viz capicola, reductus, vinctus and guttus) based on the genitalia details and external features. One new species, P.concepcioni sp.nov., is described from the West Indies and South America. New distributional records are given for all species. Pamera dubia Reuter 1882 is synonymized with Pseudopachybrachius reductus (Walker, 1872) and a neotype is designated for Rhyparochromus inconspicuus Dallas, 1852. A key and diagnostic characters of seven species are given. Phylogenetic and zoogeographic relationships are discussed. Illustrations of the genitalia, a cladogram and diagnostic external features are included.
