Distribution of representatives of the genus Neoabbottiella (Rhodophyta: Halymeniales) in the Russian Far Eastern Seas and taxonomic status of N-valentinae N. Klochkova et Pisareva, 2013

The new information on distribution of the red algae Neoabbottiella in the Russian Far East changes the concept of the areal of these algae and their preferred temperatures. A comparison of N. valentinae N. Klochkova et Pisareva with Schizymenia dubyi f. palmata Yamada collected by Y. Yamada from Urup Island and stored with its type and paratypes in the collection of Hokkaido University Museum (Sapporo, Japan) showed their conspecificity. Based on the data, N. valentinae was recognized as a synonym of Schizymenia dubyi f. palmata. Since this form does not possess the main generic feature of the genus Schizymenia and at the same time has well-expressed generic features of Neoabbottiella, the form S. dubyi f. palmata is transferred to this genus with the name N. palmata (Yamada) N. Klochkova et Pisareva.
