摘要

本文对海洋浮游硅藻属rhizzosolenia、Proboscia、Pseudosolenia和Neocalyptrella进行了形态学和系统发育的研究。材料于2008年10月至2011年1月在泰国沿海海域四个省的七个地点收集:罗勇、春武里、春丰和普吉岛。在培养中建立了50株菌株，用于形态学和系统发育分析，并辅以田间材料的形态学研究。形态学研究采用光镜、扫描电镜和透射电镜。十个物种和两个品种Rhizosolenia被确认和详细描述:r . styliformis r . acuminata r . bergonii r . clevei var. clevei, r . clevei var.普通的,r·福尔摩沙r . hyalina r . imbricata r . ostenfeldii r . aff. pungens, r . setigera和r . loanicola sp. 11月Pseudosolenia calcaravis还发现,和详细的研究表明这种分类单元形成一个物种复杂。长鼻目以籼稻P. indica和暹罗P. siamensis sp. nov为代表，但可能存在更多种类。以新桉树为代表。分子研究支持Pseudosolenia、Proboscia和Neocalyptrella为独立属。培养和分子分析往往困难或不成功。结果表明，如果将与根茎属其余种有亲缘关系的pungens和setigera作为一个新属来描述，根茎属可能是一个单系属。这将在一项关于赤藓类型材料的配套研究中进行。

The morphology and phylogeny of the diatom genera Rhizosolenia, Proboscia, Pseudosolenia and Neocalyptrella from Gulf of Thailand and the Andaman Sea, with description of Rhizosolenia loanicola sp. nov., Proboscia siamensis sp. nov. and Probosciales ord. nov.

The marine planktonic diatom genera Rhizosolenia, Proboscia, Pseudosolenia and Neocalyptrella have been studied with emphasis on morphology and phylogeny. Material was collected October 2008—January 2011 at seven localities in the four provinces of the marine coastal waters of Thailand: Rayong, Chonburi, Chumphon and Phuket. Fifty strains were established in culture and used for morphological and phylogenetic analyses, complemented with morphological studies of field material. Morphological studies were done using light microscopy, scanning and transmission electron microscopy. Ten species and two varieties of Rhizosolenia were identified and described in detail: R. styliformis, R. acuminata, R. bergonii, R. clevei var. clevei, R. clevei var. communis, R. formosa, R. hyalina, R. imbricata, R. ostenfeldii, R. aff. pungens, R. setigera and R. loanicola sp. nov. Pseudosolenia calcaravis was also found, and detailed studies indicated that this taxon formed a species complex. Proboscia was represented by P. indica and P. siamensis sp. nov., but more species probably exist. Neocalyptrella was represented by N. robusta. The molecular studies supported Pseudosolenia, Proboscia and Neocalyptrella as separate genera. Culturing and molecular analyses were often difficult or unsuccessful. The data show that Rhizosolenia can be a monophyletic genus if R. pungens and R. setigera, which are distantly related to the remaining Rhizosolenia species, are described as a new genus. This will be done in a companion study of the type material of R. setigera.

期刊介绍： Diatom Research is the journal of the International Society for Diatom Research. The journal is published quarterly, in March, June, September and December, and welcomes manuscripts on any aspect of diatom biology. In addition to full-length papers, short notes and reviews of recent literature are published which need not contain all the sections required for full-length papers; we see these as being necessary to record information which is of interest but which cannot be followed up in detail. Discursive “Opinion” papers are encouraged which would not necessarily follow the normal lay-out. If extremely long papers are to be offered, the author(s) should contact the editors first to discuss any problems. Book reviews, obituaries and meeting reports can be published. All papers will be subject to critical review by the editors and referees, as appropriate to their content. Papers will be accepted in English only.
