Synopsis of the New World Blissid Genera (Hemiptera: Heteroptera: Lygaeoidea: Blissidae): Redescriptions of Known Genera, Descriptions of Three New Genera, New Synonymies, New Combinations, Notes on Phylogeny, and a Revised Key to the Genera

Abstract

In this contribution, we provide diagnoses, redescriptions, and habitus images of the type species of the 23 known genera of New World Blissidae (Hemiptera: Heteroptera: Lygaeoidea); and describe three new genera: Brailovskyodemus, new genus to accommodate four species transferred from Extarademus [B. bifida (Slater and Brailovsky, 1990), new combination, and B. indomita (Slater and Brailovsksy, 1995), new combination] and Patritiodemus [B. clavatus (Slater and Ahmad, 1971), new combination (type species); and B. nigellus (Slater and Ahmad, 1971), new combination]; Metafemorademus, new genus, for two species transferred from Extarademus [M. mundus (Slater and Wilcox, 1966), new combination (type species); and E. prunimundus (Slater and Brailovsky, 1990), new combination]; and Prosternademus, new genus, for one species transferred from Extarademus [P. humerus (Slater and Wilcox, 1966), new combination (type species)]. In addition, we synonymize Patritiodemus Slater and Ahmad, new synonymy, with Ischnodemus Fieber, transferring the species with mutic fore femora to Ischnodemus [I. brusai (Dellapé and Montemayor, 2009), revised combination; I. dilutipes Stål, 1860, revised combination; I. minutus (Slater and Ahmad), new combination; I. singularis (Slater and Ahmad, 1971), new combination; and I. unicoloris (Slater and Ahmad, 1971), new combination] and the species with spined fore femora to Extarademus [E. albomaculatus (Slater and Ahmad, 1971), new combination; and E. delicatus (Slater and Wilcox, 1968), new combination]; and transfer five species of Patritius Distant to Riggiella Kormilev [R. alternatus (Slater and Wilcox, 1966), new combination; R. colombianus (Slater and Wilcox, 1966), new combination; R. cubensis (Barber, 1947), new combination; R. englemanni (Slater, 1979b), new combination; and R. osuna (Slater and Brailovsky, 1995), new combination]. Finally, we provide a phylogenetic analysis of the 11 New World genera having closed fore coxal cavities, based on 52 taxa (including outgroup) and 44 characters, resulting in six trees supporting the monophyly of most of the genera, and a revised key to facilitate recognition of the genera.
