摘      要：Based on a combination of morphology and molecular data of ribosomal DNA genes,a new diatom genus Lineaperpetua ***,You,Kociolek&Wang is *** 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 ***,phylogenetic analysis based on nuclear small subunit(SSU)rDNA sequences and nuclear large subunit(LSU)rDNA gene placed the three strains of *** in a single,monophyletic clade at a considerable sequence distance from the other genera(Thalassiosira,Conticribra,Planktoniella,Shinodiscus,and other genera)belonging to *** the similarities with some species of Thalassiosira,Conticribra,and Spicaticribra,the suite of features found in Lineaperpetua differentiate it from these other *** molecular data and morphological characters suggest an affinity of the new genus to the Thalassiosiraceae.
