The Mesozoic family Archegocimicidae and phylogeny of the infraorder Leptopodomorpha (Hemiptera)

Abstract

The Mesozoic hemipteran family Archegocimicidae Handlirsch is newly diagnosed and its fauna in China revised based on abundant new material. The complicated taxonomic history of the family is reviewed and the following taxonomic changes proposed: Propritergum opimum Zhang, Engel, Yao & Ren gen. et sp. nov.; Longianteclypea gen. nov.; Longianteclypea tibialis (Popov), comb. nov.; Mesolygaeus naevius (Hong), comb. nov.; Sinolygaeus Hong, synonym of Mesolygaeus Ping; and Enicocoris manlaicus Popov, Xishania fusiformis Hong, Jiaodongia maershanensis Hong, and Xishania? jiangxiensis Hong all synonyms of Mesolygaeus laiyangensis Ping. Living and fossil representatives of the infraorder Leptopodomorpha are coded for the first comprehensive phylogenetic analysis of the clade. The resulting cladogram supports the recognition of the constituent superfamilies Saldoidea and Leptopodoidea, the former containing Saldidae, Aepophilidae and Archegocimicidae, and the latter Palaeoleptidae, Omaniidae and Leptopodidae.
