The present taxonomic revision deals with Neotropical species of three entomopathogenic genera that were once included in Hypocrella s. l.: Hypocrella s. str. (anamorph Aschersonia), Moelleriella (anamorph aschersonia-like), and Samuelsia gen. nov (anamorph aschersonia-like). Species of Hypocrella, Moelleriella, and Samuelsia are pathogens of scale insects (Coccidae and Lecaniidae, Homoptera) and whiteflies (Aleyrodidae, Homoptera) and are common in tropical regions. Phylogenetic analyses of DNA sequences from nuclear ribosomal large subunit (28S), translation elongation factor 1-alpha (TEF 1-alpha), and RNA polymerase II subunit 1 (RPB1) and analyses of multiple morphological characters demonstrate that the three segregated genera can be distinguished by the disarticulation of the ascospores and shape and size of conidia. Moelleriella has filiform multi-septate ascospores that disarticulate at the septa within the ascus and aschersonia-like anamorphs with fusoid conidia. Hypocrella s. str. has filiform to long-fusiform ascospores that do not disarticulate and Aschersonia s. str. anamorphs with fusoid conidia. The new genus proposed here, Samuelsia, has filiform to long-fusiform ascospores that do not disarticulate and aschersonia-like anamorphs with small allantoid conidia. In addition, the present study presents and discusses the evolution of species, morphology, and ecology in Hypocrella, Moelleriella, and Samuelsia based on multigene phylogenetic analyses.

昆虫病原属 Hypocrella、Moelleriella 和 Samuelsia gen 的专着。十一月 (子囊菌门,Hypocreales,Clavicipitaceae),以及它们在新热带地区的类似 aschersonia 的无定形。

目前的分类学修订涉及曾经包括在 Hypocrella sl 中的三个昆虫病原属的新热带物种:Hypocrella s。海峡 (anamorph Aschersonia)、Moelleriella (anamorph aschersonia-like) 和 Samuelsia gen。nov(变形为 aschersonia 样)。Hypocrella、Moelleriella 和 Samuelsia 物种是介壳虫(球虫科和 Lecaniidae,同翅目)和粉虱(粉虱科,同翅目)的病原体,在热带地区很常见。来自核核糖体大亚基 (28S)、翻译延伸因子 1-α (TEF 1-α) 和 RNA 聚合酶 II 亚基 1 (RPB1) 的 DNA 序列的系统发育分析和多种形态特征的分析表明,这三个分离的属可以是以子囊孢子的脱节和分生孢子的形状和大小为特征。Moelleriella 具有丝状多隔膜子囊孢子,它们在子囊内的隔膜处脱节,以及具有梭状分生孢子的 aschersonia 样无定形。Hypocrella s。海峡 具有不脱节的丝状至长梭状子囊孢子和 Aschersonia s。海峡 具有梭形分生孢子的无定形。此处提出的新属 Samuelsia 具有丝状至长梭状子囊孢子,它们不会脱节,并且具有小尿囊状分生孢子的类似 aschersonia 的无定形。此外,本研究基于多基因系统发育分析,介绍并讨论了 Hypocrella、Moelleriella 和 Samuelsia 的物种、形态和生态学的进化。具有不脱节的丝状至长梭状子囊孢子和 Aschersonia s。海峡 具有梭形分生孢子的无定形。此处提出的新属 Samuelsia 具有丝状至长梭状子囊孢子,它们不会脱节,并且具有小尿囊状分生孢子的类似 aschersonia 的无定形。此外,本研究基于多基因系统发育分析,介绍并讨论了 Hypocrella、Moelleriella 和 Samuelsia 的物种、形态和生态学的进化。具有不脱节的丝状至长梭状子囊孢子和 Aschersonia s。海峡 无定形具梭形分生孢子。此处提出的新属 Samuelsia 具有丝状至长梭状子囊孢子,它们不会脱节,并且具有小尿囊状分生孢子的类似 aschersonia 的无定形。此外,本研究基于多基因系统发育分析,介绍并讨论了 Hypocrella、Moelleriella 和 Samuelsia 的物种、形态和生态学的进化。
