Abstract
We present light and scanning electron microscopical observations on two new species of Navicula Bory sensu stricto from Vietnam. These new species, Navicula babeiensis Chudaev, Glushchenko, Kulikovskiy & Kociolek sp. nov. and Navicula pseudokuseliana Chudaev, Glushchenko, Kulikovskiy & Kociolek sp. nov. are described and distinguished from others in the genus on the basis of valve outline and shape of the apices, as well as stria and areola densities. These species possess all the typical morphological features for the genus, including uniseriate lineolate striae covered by internal convex hymenes, median raphe with accessory rib, and external distal raphe ends that are hooked in the characteristic way for the genus. Comparisons with similar taxa are given. Our new data extend the information about the diversity of diatoms in general and for Navicula taxa specifically, in Southeast Asia.
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.
