Five new antlions species from the subtribe Periclystina (Myrmeleontidae: Dendroleontini)

The subtribe Periclystina is restricted to Australia and currently is represented by 63 species. Here I present five new species belonging to this group. Franzenia is known only by one species from Queensland but now a second species from Western Australia is described. Glenoleon and Austrogymnocnemia are the two largest genera of the subtribe and here one new species for each one of them are presented. Riekoleon is a small genera represented by three species all known from the forested areas of Queensland and New South Wales, here I present two new species for this genus, one from the same habitat in Queensland and the second one from Western Australia, expanding the distribution of the genus considerably.
