Abstract

A new species Mallomonas limbata sp. nov. is described from Vietnam. The description is based on silica-scale morphology studied by means TEM and SEM. The species belongs to the section Planae and has a similar morphology with species from the Mallomonas matvienkoae complex. New species has ovoid scales, narrowed distally, a developed secondary siliceous layer with internal reticulation having rounded meshes, occupying up to 4/5 of the scale surface, with numerous papillae on the surface. Scales of M. limbata were found at twenty-six localities in nine provinces of Vietnam. The distributions and habitat conditions of the new species are summarized.
