New hemipteran insects (Hylicellidae, Ipsviciidae, Heteroptera) from the Triassic Cow Branch Formation of Virginia and North Carolina, USA

Abstract Four new hemipteran insects are described from the Triassic (Norian) Cow Branch Formation of Virginia and North Carolina (USA), including one pair of isolated wings belonging to Hylicellidae (Hylicelloidea: Cicadomorpha), one complete specimen assigned to a distinctive new genus of Ipsviciidae (Scytinopteroidea: Cicadomorpha), and two heteropterans belonging to unknown families. Only the ipsviciid is preserved with enough morphological detail for systematic study and is herein described as Solitivicia reducta new genus new species due to its highly reduced forewing venation. The peculiar distribution of hemipterans in the Cow Branch Formation, namely the paucity of cicadomorphans and coleorrhynchans which are both otherwise abundant in Triassic deposits, is discussed.
