New fossil Juraphididae (Hemiptera: Aphidomorpha) from Burmese amber, with phylogeny of the family

A new aphid genus and species, Prolavexillaphis munditia Liu, Qiao and Yao gen. et sp. nov., is assigned to Juraphididae (Aphidomorpha). The specimen is described from Upper Cretaceous amber from Myanmar. In this study the phylogeny of the extinct family Juraphididae based on 33 morphological characters detailed the status of the new fossil and the relationships within the family Juraphididae. Isolitaphis prolatantennus Poinar, 2017 (Isolitaphidae) from the same deposit was also included in this phylogenetic analysis due to the similarities between two families. Two main clades within Juraphididae are recognized from our cladistic analysis: Prolavexillaphis Liu, Yao and Qiao gen. nov. and Isolitaphis (Poinar, 2017) form a monophyletic lineage; Aphaorus (Wegierek, 1991), Pterotella (Wegierek, 1991), Juraphis (Shaposhnikov, 1979) form a monophyletic lineage. These results indicate that Isolitaphis (Poinar, 2017) belongs to Juraphididae. Therefore, we propose a synonymy of Isolitaphidae with Juraphididae and the type species, Isolitaphis prolatantennus Poinar, 2017, is transferred to the Mesozoic family Juraphididae. A key to all species of Juraphididae is provided.
