Abstract

A new species, Mallomonas limbata sp. nov., is described from Vietnam. The description is based on silica-scale morphology studied by means of transmission and scanning electron microscopy. The species belongs to the section Planae and has a similar morphology with species from the Mallomonas matvienkoae complex. The new species has ovoid scales, narrowed distally, and a developed secondary silica layer with internal reticulation with rounded meshes, occupying up to 4/5 of the scale surface, with numerous papillae on the surface. Scales of M. limbata have been found at 26 localities in 9 provinces of Vietnam. The distributions and habitat conditions of the new species are summarized.

摘要

一个新物种，Mallomonaslimbata sp。11月，是从越南描述的。该描述基于通过透射和扫描电子显微镜研究的二氧化硅尺度形态。该物种属于 Planae 科，与Mallomonas matvienkoae复合体的物种具有相似的形态。新种具有卵圆形鳞片，远端变窄，有发达的次生二氧化硅层，内部有圆形网状网状结构，占据鳞片表面的4/5，表面有许多乳突。越南9个省的26个地点都发现了林巴塔鳞片。总结了新种的分布和生境条件。
