Revision of genera in Asterinales uri icon

abstract

  • The order Asterinales comprises a single family, Asterinaceae. In this study, types or specimens of 41 genera of Asterinaceae are re-examined and re-described and illustrated by micrographs. Seventeen genera, namely Asterina (type genus), Asterinella, Asterotexis, Batistinula, Cirsosia, Echidnodella, Halbania, Lembosia, Meliolaster, Parasterinopsis, Platypeltella, Prillieuxina, Schenckiella (=Allothyrium), Trichasterina, Trichopeltospora, Uleothyrium and Vizellopsis, are maintained within Asterinaceae. Echidnodes, Lembosiella, Lembosina, Morenoina, and Thyriopsis are transferred to Aulographaceae based on morphological and molecular characteristics. Anariste is transferred to Micropeltidaceae, while Lembosiopsis is transferred to Mycosphaerellaceae. Placoasterella and Placosoma are morphologically close to taxa in Parmulariaceae, where they are transferred. Aulographina is placed in Teratosphaeriaceae, while Asterodothis, Asterinema, Dothidasteromella, Leveillella, Petrakina and Stephanotheca are transferred to Dothideomycetes, genera incertae sedis. Eupelte, Macowaniella, Maheshwaramyces, Parasterinella, and Vishnumyces are treated as doubtful genera, because of lack of morphological and molecular data. Aphanopeltis, Asterolibertia, Neostomella, Placoasterina, and Symphaster are synonyms of Asterina based on morphology, while Trichamelia, Viegasia, and Yamamotoa are synonyms of Lembosia. The characteristics of each family are discussed and a phylogenetic tree is included
