Laboulbeniales parasitic on American small carrion beetles: new species of Corethromyces, Diphymyces, and Rodaucea.

Ten new species of Laboulbeniales parasitic on small carrion beetles (Coleoptera, Leiodidae, Cholevinae) from the American continent are described: Corethromyces bernardii on Dissochaetus spp. from Bolivia, Costa Rica, Ecuador, and the USA; Diphymyces anthracinus on Ptomaphagus brevior from the USA; D. blackwelliae on Ptomaphagus giaquintoi from Guatemala; D. costaricensis on Adelopsis sp. from Costa Rica; D. dichromus on Adelopsis marinae from Argentina; D. newtonii on Ptomaphagus fumosus from the USA; D. obesus on Ptomaphagus brevior from the USA; Diphymyces perreaui on Ptomaphagus nevadicus from the USA; D. polycarpus on Paulipalpina pillahuata from Peru; and Rodaucea hermanii on Adelopsis sp. from Costa Rica. The hosts for all 10 species have been retrieved from museum collections (1 was collected in the field as well). The following new combination is proposed: Rodaucea bruchii, bringing the number of species in the recently established genus Rodaucea to three.
