Notes on the Brazilian species of Purenleon Stange (Neuroptera: Myrmeleontidae), with description of two new species

摘要

This study focuses on the Brazilian species of the genus Purenleon Stange (Neuroptera: Myrmeleontidae). A total of five species are herein reported to Brazil: Purenleon clavatus (Navas), Purenleon fernandezi Miller & Stange (first record for Brazil), Purenleon cautus (Walker) comb. n., and two new species: Purenleon limeirai sp. n. and Purenleon rafaeli sp. n. The taxonomical status of other two species was reevaluated: Formicaleo bipunctatus Navas was synonymized under P. cautus and Feinerus nebulosus Navas was revalidated and transferred to Purenleon. A key to the South American species of Purenleon is also presented.
