Entomopathogenic fungi comprise an ecologically important group of specialized pathogens infecting other fungi, invertebrates, and plants. These fungi are species-rich with high diversity and broad distribution worldwide. The majority of entomopathogenic fungi belong to clavicipitoids, which consist of the hypocrealean families, Clavicipitaceae, Cordycipitaceae, Ophiocordycipitaceae, and Polycephalomycetaceae. The latter is a newly established entomopathogenic family that recently separated from the family Ophiocordycipitaceae to accommodate the genera, , and . In recent years, Polycephalomycetaceae has been enriched with parasitic and hyperparasitic fungi. With 16 species spread across China, Ecuador, Japan, and Thailand, is the most speciose genus in the family. In this study, we expand the number of taxa in the genus by introducing four new species from China, namely, , and . We provide detailed descriptions and illustrations and infer genus-level phylogenies based on a combined 6-loci gene sequence dataset comprising the internal transcribed spacer gene region (ITS), small subunit ribosomal RNA gene region (SSU), large subunit rRNA gene region (LSU), translation elongation factor 1-alpha gene region (TEF-1α), RNA polymerase II largest subunit gene region (RPB1), and RNA polymerase II second largest subunit (RPB2). This study contributes to knowledge with regard to the diversity of specifically and entomopathogenic more broadly.
昆虫病原真菌是一类在生态上具有重要意义的特殊病原体,可感染其他真菌、无脊椎动物和植物。这些真菌种类丰富,具有高度的多样性,在全球分布广泛。大多数昆虫病原真菌属于麦角菌科类群,其中包括肉座菌目下的麦角菌科、虫草菌科、蛇形虫草菌科和多顶孢菌科。多顶孢菌科是一个新建立的昆虫病原真菌科,最近从蛇形虫草菌科分离出来,以容纳[具体属名缺失]属。近年来,多顶孢菌科不断有寄生和重寄生真菌加入。[具体属名缺失]属是该科中物种最为丰富的属,在中国、厄瓜多尔、日本和泰国分布有16个物种。在本研究中,我们从中国引入了4个新的[具体属名缺失]物种,即[具体物种名缺失],从而增加了该属的分类单元数量。我们提供了详细的描述和图示,并基于一个包含内部转录间隔区基因区域(ITS)、小亚基核糖体RNA基因区域(SSU)、大亚基核糖体RNA基因区域(LSU)、翻译延伸因子1-α基因区域(TEF-1α)、RNA聚合酶II最大亚基基因区域(RPB1)和RNA聚合酶II第二大亚基(RPB2)的6个基因座的组合基因序列数据集,推断了该属水平的系统发育。本研究有助于更具体地了解[具体属名缺失]属的多样性,并更广泛地了解昆虫病原真菌的多样性。
