Abstract

This is the first phylogenetic analysis integrating both morphological and molecular data of the sponge suborder Mycalina (Poecilosclerida), which was erected in 1994. A cladistic analysis of morphology supported the monophyly of Cladorhizidae (including Euchelipluma), Guitarridae (excluding Euchelipluma), Isodictyidae, Latrunculiidae, and Podospongiidae but rejected monophyly for Desmacellidae, Esperiopsidae, Hamacanthidae, and Mycalidae. Analyses of partial 16S and partial 28S rRNA datasets combined, as well as that of a complete 18S rDNA dataset, suggest that Mycalina is not monophyletic; Biemnidae is only distantly related to other poecilosclerids; Merlia and Desmacella branch near the base of a diverse Poecilosclerida clade; Mycalidae is monophyletic (excluding Mycale [Anomomycale] titubans in 18S); and Esperiopsidae and Isodictyidae form a clade. Analyses of the two molecular datasets differed on the monophyly of Podospongiidae and about the relationship of Podospongiidae to Isodictyidae + Esperiopsidae.

摘要

这是首次将海绵亚目Mycalina（寻常海绵纲）的形态学和分子数据整合在一起的系统发育分析，该亚目于1994年建立。形态学的分支分析支持了Cladorhizidae科（包括Euchelipluma属）、Guitarridae科（不包括Euchelipluma属）、Isodictyidae科、Latrunculiidae科和Podospongiidae科的单系性，但否定了Desmacellidae科、Esperiopsidae科、Hamacanthidae科和Mycalidae科的单系性。对部分16S和部分28S rRNA数据集的联合分析，以及对完整的18S rDNA数据集的分析表明，Mycalina不是单系的；Biemnidae科与其他寻常海绵纲动物的关系较远；Merlia属和Desmacella属在一个多样化的寻常海绵纲分支的基部附近分支；Mycalidae科是单系的（在18S分析中不包括Mycale [Anomomycale] titubans）；Esperiopsidae科和Isodictyidae科形成一个分支。两个分子数据集的分析在Podospongiidae科的单系性以及Podospongiidae科与Isodictyidae科 + Esperiopsidae科的关系上存在差异。
