摘要

Abstract

A new monotypic diatom genus

Chinia

gen. nov. from estuarine mangrove habitats in Fujian

China is described. Light

scanning and transmission electron microscopy observations of its morphology show that this diatom differs from any established raphid diatom genus. The new genus is distinguished by a strongly undulate valve face

eccentric raphe canal

and perforated copulae. Its distinctly elevated and perforated raphe canal

classified as simonsenioid type

is supported by sparse infundibulum-like portulae

and the portulae are separated by large fenestrae. The valves of

Chinia

also have hymenate areolar occlusions and the raphe lacks a central nodule. However

unlike most Bacillariaceae with two plastids

including

Simonsenia

Chinia

has a single plastid similar to those in

Entomoneis

and

Surirella

. Despite the similarities to

Simonsenia

Chinia

features porous raphe canal and loose striation

which is different from those of

Simonsenia

that has a solid raphe canal and distinct rows of areolae. These distinctive cytological and morphological characters suggest an affinity of the new genus to the Bacillariaceae.
