Alienopteridae

Alienopteridae is an extinct family of dictyopterans, known from the Mid-Cretaceous to Eocene. It was originally assigned to its own order Alienoptera by Bai et al, 2016. It was reassigned to the dictyopteran superfamily Umenocoleoidea as sister family to Umenocoleidae by Vršanský et al. (2018),[1] and a more recent analysis similarly places Alienopteridae and Umenocoleidae as sister taxa within Dictyoptera, but placing both lineages outside of Blattodea.[2] The majority of the alienopterid genera are known from the Cenomanian aged Burmese amber found in Myanmar;[3][4][5][1][6][7] though an additional two genera (Apiblatta and Vcelesvab) are from the Albian Crato Formation (Brazil), and the two youngest genera (Chimaeroblattina and Grant) are from the middle Eocene Green River Formation (Colorado, United States). Some taxa have been suggested as mimics of various hymenopterans, including bees and ants.[1] However this was mostly rejected in another study.[8] Some taxa were probably predators adapted to moving through dense foliage.[8]
