          Abstract

          ABSTRACT Taxonomic revisionary notes and identification keys are presented for two species-groups of wasps of the genus Mischocyttarus, subgenus Phi. Material of the M. wagneri and M. barbatus groups, including types, was examined in several collections, resulting in description of one new species for the first mentioned group (M. camanducaia sp. nov.), and several new synonymies for both groups as follows (senior synonym in bold): [Mischocyttarus mourei Zikán 1949 = Mischocyttarus laneiZikán 1949 = Mischocyttarus plaumanniZikán 1949]; [Mischocyttarus declaratusZikán 1935 = Mischocyttarus confirmatusZikán 1935 = Mischocyttarus brackmanniZikán 1949 = Mischocyttarus alternatusZikán 1949 = Mischocyttarus cabaunaZikán 1949]; [Mischocyttarus barbatus Richards 1945 = Mischocyttarus ecuadorensisZikán 1949 = Mischocyttarus pedunculariusZikán 1949]. In addition, several cases are demonstrated of changing in group content, with species being moved into and out of groups as required. Both groups are distributed on the highlands of Central and South America, with the M. wagneri group being endemic to southeastern areas of the continent.

            Phylogeny of wasps of the genus Mischocyttarus de Saussure (Hymenoptera, Vespidae, Polistinae)

            A phylogenetic analysis is presented of subgenera and species-groups of Mischocyttarus de Saussure, the largest genus of social wasps. The analysis is based on 62 morphological and nest architecture characters, coded for 71 terminals representing much of the taxonomic diversity within the genus, plus three outgroup terminals representing other polistine tribes. The main conclusions about phylogenetic relationships within the genus are based on parsimony analysis under implied weights. Monophyly of Mischocyttarus is confirmed as well as that of most of the previously recognized subgenera: Mischocyttarus s. str., Clypeopolybia, Monogynoecus, Scytokeraia, Phi, Kappa, Megacanthopus and Omega sensu Richards (1978). Haplometrobius as conceived by Richards (1978) is not a monophyletic taxon, but some of its species-groups are monophyletic. The groups of M.artifex and M.cerberus are raised to subgenus level, and a new concept of Haplometrobius restricts it to the group of M.iheringi (the type species of this subgenus) in the sense of this work. The concept of subgenus Omega is widened to include the species-groups of M.surinamensis and M.prominulus. Besides the new subgeneric classification presented, limits and diagnoses of all species-groups of the subgenera Phi and Haplometrobius sensu Richards (1978) are discussed, and a new key for all subgenera and species-groups of Mischocyttarus is also presented.
