Abstract

Callistopteris superba is a peculiar Asian species within the genus Callistopteris (Hymenophyllaceae). A detailed morphological study of available herbarium specimens was conducted and the species was integrated into a global molecular phylogeny of the family in order to more precisely investigate its taxonomy. Morphological analysis and dated phylogenetic reconstructions demonstrate that the species is not part of Callistopteris and is instead strongly supported as being included in the distinct genus Trichomanes, comprising mainly Neotropical and some Afro-Malagasy species. The uniqueness, within the Hymenophyllaceae and the genus Trichomanes, of an indumentum of glandular-like hairs on the adaxial side of the lamina and on the indusia, allows us to propose Asiatrichomanes as a new subgenus based on this species, which is here also neotypified.

在亚洲首次记录到 Trichomanes s.s.（金银花科）并建立了新的亚属 Asiatrichomanes

Callistopteris superba是胼胝体属（Hymenophyllaceae）中一个奇特的亚洲物种。我们对现有标本馆标本进行了详细的形态学研究，并将该物种纳入该科的全球分子系统发育中，以便更精确地研究其分类学。形态学分析和年代系统发育重建表明，该物种不属于Callistopteris，而是被强烈支持归入独特的Trichomanes属，该属主要由新热带和一些非洲-马达加斯加物种组成。在半知菌科（Hymenophyllaceae）和毛癣菌属（Trichomanes）中，薄片正面和吲哚上的腺状毛是独一无二的，因此我们建议将 Asiatrichomanes 作为以该物种为基础的一个新的亚属。

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
