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

This paper describes and illustrates a new species of Laboulbeniales (Ascomycota, Laboulbeniomycetes) recovered fromMastoptera guimaraesibat flies (Diptera, Streblidae) in Ecuador and Panama. Bat fly-associated Laboulbeniales are still unexplored in the Neotropics, with only four described species ofGloeandromycesand one species ofNycteromycesknown. Morphological characteristics and phylogenetic analyses support placement of the new taxon inGloeandromycesand its recognition as an undescribed species.Gloeandromyces hillerisp. 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 1 alpha (TEF1) both resolveG. hilleriandG. nycteribiidarumas sister species. We discuss the utility of LSU andTEF1as secondary barcodes in Laboulbeniomycetes taxonomy.
