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

Abstract

ABSTRACT This paper describes and illustrates a new species of Laboulbeniales (Ascomycota, Laboulbeniomycetes) recovered from Mastoptera guimaraesi bat flies (Diptera, Streblidae) in Ecuador and Panama. Bat fly–associated Laboulbeniales are still unexplored in the Neotropics, with only four described species of Gloeandromyces and one species of Nycteromyces known. Morphological characteristics and phylogenetic analyses support placement of the new taxon in Gloeandromyces and its recognition as an undescribed species. Gloeandromyces hilleri 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 (TEF1) both resolve G. hilleri and G. nycteribiidarum as sister species. We discuss the utility of LSU and TEF1 as secondary barcodes in Laboulbeniomycetes taxonomy.
