Abstract

Light and scanning electron microscope observations on the genus Fontina gen. nov. from a thermo-mineral spring of the Massif Central (France) are presented. Based on morphology, the new genus shows features that have not been described previously, such as the stria pattern, interrupted at the valve face/mantle junction and composed of one long, slit-like areola on both valve face and mantle. Externally, areolae are closed by hymenes. Fontina arverna sp. nov. is described as the typus generis of Fontina. This new genus was compared with some similar freshwater genera such as Adlafia, Chamaepinnularia, Genkalia, Germainiella, Microfissurata and Nupela. So far, we are unable to establish an evolutionary link or cladistic association with currently known genera. The new genus is described from a sampling site characterized by high conductivity and high carbonate concentration, brackish conditions and whose water originates deep in the crust (high lithium concentration).

Fontina Gen.nov.（硅藻门）：法国中部地块热矿泉中的一个新硅藻属

本文报道了法国中部地块热矿泉中的Fontina gen. 11 .的光镜和扫描电镜观察结果。在形态学上，新属显示出以前没有描述过的特征，如条纹图案，在阀面/地幔交界处中断，在阀面和地幔上由一个长而裂缝状的乳晕组成。在外部，乳晕被处女膜封闭。Fontina arverna sp. 11 .被描述为Fontina的典型属。将该属与Adlafia、Chamaepinnularia、Genkalia、Germainiella、Microfissurata和Nupela等淡水属进行了比较。到目前为止，我们还不能与目前已知的属建立进化联系或分支关系。这个新属是在一个具有高电导率和高碳酸盐浓度、半咸水条件和水起源于地壳深处(高锂浓度)的采样地点描述的。

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.
