THE SYSTEMATIC POSITION OF THE IPSVICIIDAE (UPPER TRIASSIC HEMIPTERA) AND SOME NEW UPPER PERMIAN AND MIDDLE TRIASSIC HEMIPTERA FROM AUSTRALIA (INSECTA)

Abstract

AbstractThe Ipsviciidae are a family of Hemiptera, which, up to the present, have been recorded only from Upper Triassic strata in Queensland. The venation of their tegmina is anomalous and has proved difficult to interpret. Consequently, their relationships with other groups of Hemiptera have been uncertain. In a recent publication, China has suggested that the Ipsviciidae are related to an extant family of primitive Homoptera, the Peloridiidae (China 1962). This suggestion is examined, but not accepted. Instead, evidence is given to show that, more probably, the Ipsviciidae belonged to the superfamily Cercopoidea. The affinities of the family Stenoviciidae are discussed and some new Hemiptera of unusual interest described from Australian Upper Permian and Middle Triassic strata.
