New data on thysanurans preserved in Burmese amber (Microcoryphia and Zygentoma lnsecta)
Abstract
One undeterminable Microcoryphia specimen preserved in burmite, almost certainly belonging to the genus em>Macropsontus, is reported. One new Lepismatidae (Zygentoma), Cretolepisma kachinicum gen. n. sp. n., preserved in the same ca. 100 MY old Albian-Cenomanian amber from Myanmar, is described based upon one female. It is compared with the recent genera in the nominate subfamily as well as with Burmalepisma cretacicum Mendes & Poinar, 2008, the only other species of Zygentoma known to date from the same deposits. Some paleogeographical and phylogenetic data are discussed and one new combination is proposed.
