A new species of the genus Retiboletus, Retiboletus huanggangensis, collected from Huanggang mountain, Wuyishan Nature Reserve, Yanshan County, Shangrao City, Jiangxi Province, China, is described based on morphological and phylogenetic analysis, nuclear ribosomal large subunit (nrLSU), the translation elongation factor1-α gene (TEF1-α) and the RNA polymerase II second largest subunit gene (RPB2) were used for phylogenetic analysis. Retiboletus huanggangensis is morphologically characterized by
