Title

A new freshwater species Achnanthidium kangdingnese (Bacillariophyta, Achnanthidiaceae) from Sichuan Province, China

Abstract

A new freshwater diatom species, Achnanthidium kangdingnese Yu, You & Wang, sp. nov. from Sichuan Province, China, is described. The morphology of this species was analyzed with scanning electron microscopy (SEM) and light microscopy (LM). A. kangdingnese belongs to the A. initium-like subgroup, which has external distal raphe ends curved in opposite directions of the valve. The main characteristics of A. kangdingnese are its linear shape, rounded apices and transpically-elongated areolae on the both valves. The central area is well defined with one or two spaced striae of the raphe valve. And on the internal valve, areolae are occluded by hymens perforated by delicate slits, and each hymen is closely joined with the adjacent hymen. We compared the new species with other similar species of Achnanthidium, A. kangdingnese is considered to be sufficiently different from other similar species based on valve outline, shape of the axial and center areas, and striae density. The new species is known only from its type locality, a mountain lake in Kangding County.
