摘要

Abstract

Based on a combination of morphology and molecular data of ribosomal DNA genes

a new diatom genus

Lineaperpetua

gen. nov. Yu

You

Kociolek

Wang is described. The features that help define

Lineaperpetua

at the level of genus include: a tangentially undulated valve face; continuous cribra areolae on the valve interior consisting of pores arranged as strips; single rimoportula located inside the ring of marginal fultoportulae. Additionally

phylogenetic analysis based on nuclear small subunit (SSU) rDNA sequences and nuclear large subunit (LSU) rDNA gene placed the three strains of

lacustris

in a single

monophyletic clade at a considerable sequence distance from the other genera (

Thalassiosira

Conticribra

Planktoniella

Shinodiscus

and other genera) belonging to Thalassiosirales. Despite the similarities with some species of

Thalassiosira

Conticribra

and

Spicaticribra

the suite of features found in

Lineaperpetua

differentiate it from these other genera. These molecular data and morphological characters suggest an affinity o

f the new genus to the Thalassiosiraceae.
