Cymbella turgidula var. nipponica Skvortsov, nom. illeg. 1937

Publication details
Cymbella turgidula var. nipponica Skvortsov 1937: 283, figs 2:8, 4:4, nom. illeg.

Published in: Skvortzov, B.V. (1937 '1936'). Diatoms from Kizaki Lake, Honshu Island, Nippon. Philippine Journal of Science. Section C 61(2): 253-296, 8 pls.

Type species
The type species (lectotype) of the genus Cymbella is Cymbella cymbiformis C.Agardh.

Status of name
This name is currently regarded as a synonym of Cymbella rheophila T.Ohtsuka

Type information
Type locality: Lake Biwa, Japan (Ohtsuka & Tuji 2002). Lectotype: Fig. 7 (epitype) Tamiji Kawamura; 3 November, 1915; Lake Biwa Museum, Shiga, Japan Slide 30000136 (Ohtsuka & Tuji 2002: 245, 243, fig. 7). Notes: Isolectotype (raw material): TNS-AL-53965 m (Tuji, 2007).

No synonyms are currently included in AlgaeBase.

Taxonomic notes
Ohtsuka & Tuji (2002: 245) consider the current taxonomic status as a variety of C. turgidula to be inadequate as the two forms often coexist in the same locality but with habitat segregation. As 'Cymbella niponica' becomes a later synonym of C. nipponica Skvortzow 1936, they propose the substitute name Cymbella rheophila Ohtsuka. - (13 Mar 2007) - Wendy Guiry

General environment
This is a freshwater species.

This variety tends to inhabit running water or upper parts of rivers.
