Birmaniaespina robustispina gen. et sp. nov., a new yuripopovinid bug from Cenomanian Kachin amber, Myanmar (Hemiptera, Pentatomomorpha)

Abstract

The true bug family Yuripopovinidae was first reported in Lower Cretaceous amber of central Lebanon, and subsequently documented in the Lower Cretaceous of northeastern China and Cenomanian Kachin amber of Myanmar. Based on one well-preserved bug fossil trapped in Kachin amber, we herein describe and illustrate another new yuripopovinid taxon, Birmaniaespina robustispina gen. et sp. nov. The new genus and species can be easily distinguished from known yuripopovinids by bearing a series of deviant autapomorphic characters: one horn arranged on each lateral margin of head behind compound eye, pronotal posterior lobe surface reticular, and ovipositor extremely long and apparently extending beyond pygofer. The new bizarre yuripopovinid further evidences that this extinct pentatomomorph lineage once diversified multi-dimensionally and was flourishing in the late Mesozoic.
