is a genus within Ophiocordycipitaceae, primarily parasitising insect groups such as ants (Hymenoptera), moth larvae (Lepidoptera) and beetle larvae (Coleoptera). The genus is characterised by cylindrical stipes, subglobose to globose fertile heads with immersed perithecia, hyaline, multi-septate ascospores and irregularly branched conidiophores with flask-shaped phialides and cylindrical to fusiform conidia. is globally distributed, primarily inhabiting tropical and subtropical locations; however, it has also demonstrated adaptability to temperate climates. This study introduces two novel species and reports one asexual morph of from China, providing detailed descriptions, illustrations and molecular phylogenetic analyses. Morphological examination reveals clear distinctions between the new species and previously described taxa. Multi-locus phylogenetic analyses (LSU, ITS, SSU, -1α, 1 and 2) corroborate their uniqueness, offering new insights into the diversity and evolutionary dynamics of the genus.
是蛇形虫草科的一个属，主要寄生于昆虫群体，如蚂蚁（膜翅目）、蛾幼虫（鳞翅目）和甲虫幼虫（鞘翅目）。该属的特征是菌柄圆柱形，产孢头近球形至球形，子囊壳埋生，子囊孢子透明、多隔膜，分生孢子梗不规则分枝，具瓶形瓶梗和圆柱形至梭形分生孢子。全球分布，主要栖息于热带和亚热带地区；然而，它也表现出对温带气候的适应性。本研究介绍了两个新物种，并报道了来自中国的一个无性型，提供了详细的描述、插图和分子系统发育分析。形态学检查揭示了新物种与先前描述的分类群之间的明显区别。多位点系统发育分析（LSU、ITS、SSU、-1α、1和2）证实了它们的独特性，为该属的多样性和进化动态提供了新的见解。
