Abstract

Study of silica-scaled chrysophytes in Vietnam has revealed a rare species, endemic to Australia, in three Vietnamese water bodies outside of its previously known habitats. The investigations were conducted in the freshwaters of Vietnam using the electron-microscopic method and high-throughput sequencing (V9-ITS1 rDNA metabarcoding). Descriptions, original micrographs, and habitat features of this species are given.


Keywords: Chrysophyceae, electron-microscopic study, high-throughput sequencing, Vietnam
