摘要

2018年6月11日，在韩国顺天湾的潮滩沉积物中采集了一个未知的吉芬尼亚分类群。通过光镜、电镜分析和文献综述，对该物种进行了鉴定。重要的形态学特征是薄唇形胸骨、细长的肺泡和偏心的中缝。这些特征在先前描述的gifenia分类群(gifenia cocconeiformis)中不存在。新硅藻种的特征是:(1)瓣面略起伏，(2)唇形胸骨表面略粗糙，(3)瓣面上有许多细长的肺泡，(4)偏心的中缝。本文提出韩国吉菲尼亚硅藻属(Giffenia koreana sp. 11 .)为新的藻门上硅藻分类群。

Giffenia koreana sp. nov. (Bacillariophyta): A newly identified epipelic diatom in the tidal flat sediments of Suncheonman Bay, extant for over 1,400 Years

An unknown Giffenia taxon was sampled from the tidal flat sediment of Suncheonman Bay in the Republic of Korea on June 11, 2018. To identify the species, a detailed analysis using light and electron microscopy and a literature review were conducted. The important morphological characteristics—thin lip-shaped sternum, elongated alveoli, and eccentric raphe slit—were found in the species. These features are not present in previously described Giffenia taxa (Giffenia cocconeiformis). The new diatom species is characterized by (1) a slightly undulated valve face, (2) a lip-shaped sternum with a slightly rough surface, (3) numerous elongated alveoli on the valve face, and (4) an eccentric raphe slit. We propose Giffenia koreana sp. nov. as a new epipelic diatom taxon.

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.
