Synopsis of Australian Calymmochilus Masi (Hymenoptera: Eupelmidae), description of a new Western Australian species associated with a pseudoscorpion, and review of pseudoscorpion parasites

Abstract

The recognised Australian species of the eupelmid genus Calymmochilus Masi are reviewed. Diagnoses are presented for all described species and notes provided on eight potential new species, which are not named due to a lack of material and matched sexes. Calymmochilus longbottomi Gibson from Western Australia, reared from the pseudoscorpion Synsphyronus lathrius Harvey, is described as new, and Eupelmus longifasciatipennis Girault is transferred to Calymmochilus as a result of the previous synonymy of Tasmanastatus Bouček. Information is presented on morphological variation within and between species, their distribution and relationships, as well as a key to all known species, including those which are as yet unnamed. The occurrence of pseudoscorpion parasites (Hymenoptera, Acari and Nematoda) is reviewed, the record of C. longbottomi being highlighted as the first report of a chalcidoid associated with a pseudoscorpion.
