Abstract

<jats:sec><jats:title>Abstract</jats:title><jats:p>Lebanoraphidia nana gen. et sp.n. is described from the Lower Cretaceous amber of Lebanon and represents the smallest known Raphidioptera. The new taxon is quite similar in its minute size, large compound eyes and wing venation to Nanoraphidia electroburmica (Mesoraphidiidae) from the Lower Cretaceous amber of Myanmar, as well as to 'Mesoraphidia' luzzii from the Upper Cretaceous amber of New Jersey, and Cantabroraphidia marcanoi from the Lower Cretaceous El Soplao amber of Spain. For the species 'Mesoraphidia' luzzii a new genus, Grimaldiraphidia, is erected, because it would otherwise render the genus Mesoraphidia paraphyletic.
