New report of two Nemoleontinae species from the Korean Peninsula (Neuroptera, Myrmeleontiformia, Myrmeleontidae)

Pseudoformicaleo and Paraglenurus are genera belonging to the tribes Nemoleontini and Megistopini of Nemoleontinae, respectively. Prior to this study, Pseudoformicaleo had not been recorded in the Korean Peninsula, while three species of Paraglenurus ( Paraglenurus albiventris Matsumoto, Kikuta & Hayashi, 2021, Paraglenurus japonicus (McLachlan, 1867), and Paraglenurus melanostictus Matsumoto, Kikuta & Hayashi, 2021) have been recorded in the country. In this paper, Pseudoformicaleo nubecula (Gerstaecker, 1885) and Paraglenurus okinawensis (Okamoto, 1910) are reported from the Korean Peninsula for the first time. A diagnosis and supplementary description of both species are provided, together with illustrations of the adult and genitalia. An updated key to species of Korean Nemoleontinae is also provided.
