ABSTRACT
Three new species, Nycteromyces orientalis, Dimeromyces capensis, and D. streblidarum, belonging to the Laboulbeniales (Fungi, Ascomycota) and collected on bat flies (Diptera, Streblidae), are described and illustrated. The new species of Nycteromyces is the second described in this rarely collected genus, with the type species, N. streblidinus, previously collected only three times from Venezuela, Panama, and Honduras. The material for our new species comes from Australia, India, Philippines, and Tanzania, and morphological characters of these new collections require emendation of the original generic diagnosis. The distribution of N. streblidinus is also extended with additional collections from Costa Rica and Peru. We describe two new species of Dimeromyces from streblid hosts, the first report of any members of this large, diverse genus on this host family. Newly described taxa are compared with known species and the genera Nycteromyces and Dimeromyces discussed in relation to other known Laboulbeniales taxa.
