A new species of<i>Gloeandromyces</i>from Ecuador and Panama revealed by morphology and phylogenetic reconstruction, with a discussion of secondary barcodes in Laboulbeniomycetes taxonomy

Resumen

This paper describes and illustrates a new species of Laboulbeniales (Ascomycota, Laboulbeniomycetes) recovered from <i>Mastoptera guimaraesi</i> bat flies (Diptera, Streblidae) in Ecuador and Panama. Bat fly-associated Laboulbeniales are still unexplored in the Neotropics, with only four described species of <i>Gloeandromyces</i> and one species of <i>Nycteromyces</i> known. Morphological characteristics and phylogenetic analyses support placement of the new taxon in <i>Gloeandromyces</i> and its recognition as an undescribed species. <i>Gloeandromyces hilleri</i> sp. nov. is easily recognized by 2-3 longitudinal rows of undulations at its perithecial venter. Phylogenetic reconstructions of the large subunit (LSU) ribosomal DNA and the translation elongation factor 1α (<i>TEF1</i>) both resolve <i>G. hilleri</i> and <i>G. nycteribiidarum</i> as sister species. We discuss the utility of LSU and <i>TEF1</i> as secondary barcodes in Laboulbeniomycetes taxonomy.
