Abstract: | ABSTRACT The Trachypetidae is a newly recognised family of Ichneumonoidea endemic to Australia and one of the most distinctive wasp groups on the continent based on their large body size and superficial resemblance to some ichneumonids and aculeate wasps. The family is united in the presence of a unique sensory or glandular structure at the base of the mandibles. It is known from three genera: Cercobarcon Tobias, 1979, Megalohelcon Turner, 1918 (= Rhamphobarcon Tobias, 1979) and Trachypetus Guérin de Méneville, 1830, totalling eight described species. Trachypetines are rarely encountered, with very few specimens having been collected or recognised in collections since the group was revised in 1993. Here we report on a newly discovered species from Cape York Peninsula, Queensland, the first to be recognised in more than 25 years, and take much pleasure in naming it after Dr John La Salle, in celebration of his career.http://www.zoobank.org/urn:lsid:zoobank.org:pub:3F0147A8-F628-4869-B7FD-2E1560145734 |
