摘要

摘要:本文报道了一种来自印度东高止山脉的新的无尖藻形硅藻的光和扫描电镜观察。这个物种,和一个来自西高特山脉的有柱头的紧密联系的物种,在对称和某些阀特征方面与Gomphonemataceae的其他成员相似。然而,它们的不同之处在于在两端都有不同的孔场群。在顶杆处,承载气孔群的区域被压平并位于阀套上,在光学显微镜下不容易看到。对于这些种,我们建议将其归为贡花科的Indiconema gen. 11。我们根据瓣带和带带的特征评估了这一类群的系统发育位置和科内的关系,这表明该新属是非洲特有属非洲伞菌的姐妹属。我们将这一基础系统发育位置与在印度西高止山脉和东高止山脉发现的其他生物群以及Gomphonemataceae化石分类群进行了比较。与非洲已知的一个属的姊妹分类群关系支持了这两个地区的植物区系的密切关系。关键词:双足硅藻系统发育gomphonemataceae herculleana群西高止山脉Karthick感谢Agharkar研究所所长提供的设施和鼓励以及南非Potchefstroom西北大学的Jonathan Taylor博士。声明作者未报告潜在的利益冲突。本研究得到了印度科学与工程研究委员会(塞尔维亚,CRG/2021/004668)的支持。这次野外考察是由国家地理学会探险基金(资助号:9224-12)资助的。

A new freshwater gomphonemoid diatom genus from India, with the description of a new species from the Eastern Ghats
ABSTRACTWe present light and SEM observations of a new astigmate gomphonemoid diatom from the Eastern Ghats of India. This species, and a closely allied one from the Western Ghats that has a stigma, are similar to other members of the Gomphonemataceae in terms of symmetry and certain valve features. They differ, however, in having groups of differentiated pore fields at both apices. At the headpole, the area bearing the groups of pores is flattened and positioned on the valve mantle, and is not easily seen in light microscopy. For these species we propose the genus Indiconema gen. nov. within the Gomphonemataceae. We evaluate the phylogenetic position of this group and relationships within the family based on valve and girdle band features, which suggest that the new genus is sister to Afrocymbella, a genus apparently endemic to Africa. We compare this basal phylogenetic position with other groups of organisms also found in the Western and Eastern Ghats of India, as well as to fossil taxa in the Gomphonemataceae. The sister taxon relationship with a genus known only from Africa supports a close relationship of the floras of the two regions.KEYWORDS: BiraphidDiatom phylogenyGomphonemataceaeHerculeana groupWestern Ghats ACKNOWLEDGEMENTSB.
