Maroninaaustraliensis Hafellner & R. W. Rogers. Type. AUSTRALIA (Fig. 3). Queensland, Tandora about 25 km ENE of Maryborough, sea level, 25°27'S, 152°52'E, mangroves, on Rhizophorastylosa, 23 August 1986, J. Hafellner 17823 & R. W. Rogers (holotype GZU).

Based on molecular and phenotypical evidence, we propose Maronina s.str. to be a strictly Australian genus, comprising M.australiensis and M.hesperia Kantvilas & Elix only, as was suggested by Kantvilas and Elix (2007)) and Kantvilas et al. (2010). The genus Maronina contains depsides instead of depsidones as found in Neoprotoparmelia. Paraphyses in Maronina are slender and mostly simple, whereas those in Neoprotoparmelia are branched and anastomosing.
