Taxonomic notes on social wasps of the groups of Mischocyttarus wagneri (Buysson 1908) and M. barbatus Richards 1945 (Hymenoptera, Vespidae, Polistinae)

摘要

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 Zikan 1949 = Mischocyttarus lanei Zikan 1949 = Mischocyttarus plaumanni Zikan 1949]; [Mischocyttarus declaratus Zikan 1935 = Mischocyttarus confirmatus Zikan 1935 = Mischocyttarus brackmanni Zikan 1949 = Mischocyttarus altematus Zikan 1949 = Mischocyttarus cabauna Zikan 1949]; [Mischocyttarus barbatus Richards 1945 = Mischocyttarus ecuadorensis Zikan 1949 = Mischocyttarus peduncularius Zikan 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.
