Pabuonqedidae is the most recently erected extinct family of Blattaria, with only a type genus and species reported from the Cretaceous. Pabuonqed magna sp. n., based on a well-preserved specimen from mid-Cretaceous Kachin amber, can be definitely attributed to the genus, but differs from the type species, Pabuonqed eulna VRSANSKY, 2019, mainly by large body size, filiform bases on antennae, smaller, round eyes, standard pronotum (all plesiomorphies), absence of arolium on mesotarsus (autapomorphies), developed R and narrow cubitus in forewing, and developed Sc and R in hindwing. As the second species of Pabuonqedidae, our new find provides more information on the phylogenic position of Pabuonqedidae and augments the biodiversity of the Cretaceous wood-boring and/or rotten wood-burrowing mole roaches.
