Ophiocordycepsaphrophoridarum sp. nov., a new entomopathogenic species from Guizhou, China

BACKGROUND: Ophiocordyceps is the largest genus in the family Ophiocordicipitaceae, including many entomopathogenic species. In recent years, many species have been described in this genus, with a wide range of host insects. Entomopathogenic fungi include ecologically, economically and medicinally i...

Sumario:BACKGROUND: Ophiocordyceps is the largest genus in the family Ophiocordicipitaceae, including many entomopathogenic species. In recent years, many species have been described in this genus, with a wide range of host insects. Entomopathogenic fungi include ecologically, economically and medicinally important species, but a large portion of their diversity remains to be discovered and described. NEW INFORMATION: In this study, a new species, Ophiocordycepsaphrophoridarum sp. nov, parasitising Aphrophoridae sp. (Hemiptera) is proposed from China, based on evidence from morphology and molecular phylogenetic analyses. This species is characterised by fibrous, pigmented stromata, cylindrical asci and filiform ascospores. Compared to its closest relative, O.tricentri, the new species has wider perithecia and longer asci. Molecular phylogenetic analyses of a multilocus dataset (consisting of SSU, ITS, LSU, TEF1, RPB1 and RPB2) confirm its placement in Ophiocordyceps. Ophiocordycepsaphrophoridarum is morphologically described and illustrated with colour photographs. Morphological comparisons with closely-related species are also presented in tabulated format.
