Abstract

A new cymbelloid diatom species from the genus Cymbopleura (Krammer) Krammer is described on the basis of molecular and morphological investigations. Cymbopleuranatellia Glushchenko, Kulikovskiy & Kociolek, sp. nov. is, on the basis of results with molecular data, close to C.naviculiformis (Auerswald ex Heiberg) Krammer. The two species differ both by molecular distance and morphological features. Morphologically, C.natellia sp. nov. is compared with several other species in the genus. This work is a pioneer investigation of cymbelloid taxa using molecular tool from Transbaikal area.

Keywords: Bacillariophyceae; Cymbopleura; Russia; molecular investigation; morphology; new species.

Phylogenetic position of Cymbopleuranatellia B209 (indicated in bold) based on Bayesian inference for the partial 18S rDNA gene. Total length of the alignment is 439 characters. Bootstrap supports from ML (constructed by RAxML) and posterior probabilities from BI (constructed by Beast) are presented on the nodes in order. Only BS and PP above 50 and 0.85 are shown. Strain numbers (if available) and GenBank numbers are indicated for all sequences.
