is entomopathogenic and the largest studied genus in the family . Many species in this genus have been reported from Thailand. The first new species introduced in this paper, , differs from other species based on its smaller perithecia, shorter asci and secondary ascospores and additionally, in parasitising fly species. Phylogenetic analyses of combined LSU, SSU, ITS, TEF1α and RPB1 sequence data indicate that forms a distinct lineage within the genus as a new species. The second new species, , is distinguished from closely related species by infecting larvae of insects (Coleoptera, Elateridae) and by producing white to brown sporangia, longer secondary synnemata and shorter primary and secondary phialides. We introduce based on its significant morphological differences from other similar species, even though phylogenetic distinction is not well-supported.
具有昆虫致病性，是该科中研究最多的属。该属的许多物种已在泰国被报道。本文介绍的第一个新物种，与其他物种的不同之处在于其较小的子囊壳、较短的子囊和次生囊孢子，此外，它寄生于蝇类物种。对 LSU、SSU、ITS、TEF1α 和 RPB1 序列数据进行联合系统发育分析表明，作为一个新物种，在该属内形成了一个独特的谱系。第二个新物种，通过感染昆虫（鞘翅目，叩头虫科）的幼虫以及产生白色至棕色的孢子囊、更长的次生分生孢子梗和更短的初生和次生瓶梗，与近缘物种区分开来。尽管系统发育差异没有得到充分支持，但基于其与其他相似物种的显著形态差异，我们介绍了 。
