| Abstract: | Two new palaeoleontid species, Baisopardus escuilliei sp. nov. and Baisopardus pumilio sp. nov., are described, based on compression fossils from the Crato Formation in northeastern Brazil. The external morphology, particularly the wing venations, are analysed and compared with all genera of Palaeoleontidae. The previously proposed synonymy of Baisopardus with Neurastenyx is discussed. Neurastenyx, proven to be a poorly known genus based on an incomplete type fossil, is limited to its sole type species as a Myrmeleontoidea incertae sedis nov. sit. Consequently the genus Baisopardus is restored and all the other species previously included in Neurastenyx are transferred into Baisopardus. |
