Reclassification of the New World antlion genera formerly included in the tribe Brachynemurini (Neuroptera: Myrmeleontidae)

A cladistic analysis of the New World tribe Brachynemurini has resulted in several new taxonomic designations. The tribe is divided into 3 tribes, 2 of which are newly described. The Brachynemurini s.s. now contains 12 genera of which Argentoleon, Atricholeon, Mexoleon and Venezueleon are newly described. The Gnopholeontini (NEW TRIBE) includes 4 North American genera whereas the Lemolemini (NEW TRIBE) contains 6 South American genera of which Ecualeon. and Galapagoleon are newly described. Descriptions of genera in the 3 tribes, based on adults and known larvae, are given. Keys to the genera in each tribe are provided, as well as a key to the tribes of Myrmeleontidae.
