First Description of <i>Akanthomyces uredinophilus</i> comb. nov. from Hemipteran Insects in America
Filamentous fungi of the genera <i>Lecanicillium</i> and <i>Akanthomyces</i> (Ascomycota: Hypocreales: Cordycipitaceae) have been isolated from a variety of insect orders and are of particular interest as biological control agents for phloem-sucking plant pests. Three aphid-...

| description | Filamentous fungi of the genera <i>Lecanicillium</i> and <i>Akanthomyces</i> (Ascomycota: Hypocreales: Cordycipitaceae) have been isolated from a variety of insect orders and are of particular interest as biological control agents for phloem-sucking plant pests. Three aphid- and whitefly-pathogenic fungal strains that had been isolated from naturally infected <i>Trialeurodes vaporariorum</i> and <i>Myzus persicae</i> in Argentina were assigned to the species <i>Lecanicillium uredinophilum</i> by combined analyses of morphology and ITS, LSU, EF1A, RPB1 and RPB2-based molecular taxonomy, giving rise to both the first description of this fungus from hemipteran insects and its first report from outside South-East Asia, especially from the American continent. A combination of phylogenetic reconstruction and analysis of pair-wise sequence similarities demonstrated that—reflecting recent changes in the systematics of Cordycipitaceae—the entire species <i>L. uredinophilum</i> should be transferred to the genus <i>Akanthomyces</i>. Consequently, the introduction of a new taxon, <i>Akanthomaces uredinophilus</i> comb. nov., was proposed. Moreover, extensive data mining for cryptic <i>A. uredinophilus</i> sequences revealed that (i) the fungus is geographically widely distributed, including earlier unrecognized isolations from further American countries such as the USA, Mexico, and Colombia, and (ii) entomopathogenic and mycoparasitic lifestyles are predominant in this species. |
