摘要

Abstract

An interesting group of cymbelloid diatoms was collected from lakes in Yunnan Province

China

and observations on their valve morphology made using light and scanning electron microscopy. These cymbelloid species all have apical pore fields

slit-like areolae

and areolar occlusions

and they all lack of stigmata. In this paper we propose the new genus

Qinia

gen. nov. for these taxa and describe them as new:

lashii

sp. nov.

aequalis

sp. nov.

and

daliensis

sp. nov. The genus

Qinia

gen. nov. has lanceolate valves asymmetrical about their apical axes

raphe located in the middle of valve

distal raphe ends bent to the dorsal margin that bisects the apical pore fields (APFs)

no stigmata

areolae with slit-like externa

l openings and projections occluding the areolar openings internally. This genus resembles the genus

Cymbella

in the presence of APFs

but differs from

Cymbella

by a lack of stigmata

and by having external distal raphe ends that bisect the apical pore fields. Like

Reimeria

the external distal raphe ends bisect the lobes of the APF

but

Qinia

species differ from

Reimeria

in that they have no stigmata and the distal raphe ends are deflected dorsally

not ventrally. Comparisons were made between

Qinia

and other cymbelloid genera whose members possess apical pore fields. Features that distinguish each species of the new genus are also discussed.
