摘要

摘要:通过透射电镜和扫描电镜对越南Mallomonas viet ica Gusev, Kezlya & Tran, sp. nov.的硅尺度形态进行了描述。该物种属于Mallomonas Perty剖面，其特征是大的椭圆形鳞片，具有宽而深的圆顶，从鳞片周长凹陷。圆顶被移到尺度的右侧，并与尺度的纵轴成不同的角度。新描述的分类群的刚毛具有明显钩足的特征。M. vietnamica Gusev, Kezlya & Tran, sp. 11 .的鳞片仅在河内的一个地方被发现，在淡水大河的巴维国家公园边界(Sông Đà)。

Mallomonas vietnamica Gusev, Kezlya & Tran, sp. nov. (Synurales, Chrysophyceae), a New Species, that Shares Some Features with Fossil Taxa

ABSTRACT A new species, Mallomonas vietnamica Gusev, Kezlya & Tran, sp. nov., is described from Vietnam based on silica-scale morphology elucidated by transmission and scanning electron microscopies. The species belongs in section Mallomonas Perty and is characterized by large oval scales with a wide and deep dome, which is recessed from the scale perimeter. The domes are shifted to the right side of scales and oriented at different angles to the scale's longitudinal axis. Bristles of the newly described taxon are characterized by a distinctly hooked foot. Scales of M. vietnamica Gusev, Kezlya & Tran, sp. nov. were found at only one locality in Hanoi, at the border of Ba Vi National Park in the freshwater Da River (Sông Đà).
