本分类修订涉及三个昆虫病原属的新热带种，它们曾被包括在竹红菌属中。l.：竹红菌属str.（无性型座壳孢属）、Moelleriella（无性型座壳孢属样）和Samuelsia gen. nov（无性型座壳孢属样）。竹红菌属、Moelleriella和Samuelsia是介壳虫（蚧科和蜡蚧科，同翅目）和粉虱（粉虱科，同翅目）的病原体，在热带地区很常见。核核糖体大亚基（28 S）、翻译延伸因子1-α（TEF 1-α）和RNA聚合酶II亚基1（RPB 1）的DNA序列的系统发育分析和多个形态特征的分析表明，这3个分离的属可以通过子囊孢子的断节和分生孢子的形状和大小来区分。Moelleriella具有丝状多隔子囊孢子，其在孢子囊内的隔处分开，并且具有梭状分生孢子的aschersonia样无性型。竹红菌属str.有丝状到长梭形的子囊孢子，不分节，座壳孢属。具梭状分生孢子的无性型。新属Samuelsia，具有丝状到长梭形的子囊孢子，不分节，具有小的尿囊状分生孢子的类球壳孢无性型。此外，本研究提出和讨论的物种，形态和生态的进化在肉座菌，Moelleriella，和Samuelsia基于多基因系统发育分析。
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-α (TEF 1-α), 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.
