A new parasitic fungus on the cleptoparasite of bees Braula coeca (Insecta, Diptera): Dimeromyces braulae (Ascomycota, Laboulbeniales)

摘要

A new species of Dimeromyces (Ascomycota, Laboulbeniales) parasitic on the bee louse Braula coeca Nitzsch (Diptera, Braulidae) is described. The most obvious differences between the new species and the others are the more inflated and more numerous antheridia (up to ten), the longer appendages, and the distinctly truncate perithecial apex. The fungus appears to be relatively common in the Czech Republic, with an infection rate of 12.6% (n = 372).
