Gymnogongrus flabelliformis Harvey

Taxonomic notes
Gymnogongrus? - (28 Mar 2021) - Wendy Guiry

Distributional notes
This species was introduced accidentally, probably via oysters from Japan, into the Mediterranean (Verlaque et al. 2015: 187), being first found in the Etang de Thau (France) in 1994. - (5 Nov 2015) - M.D. Guiry

According to Shibneva et al. (2020: 81), species of the genus Ahnfeltiopsis sensu stricto do not occur in the seas of the Russian Far East, and the algae previously identified as 'A. flabelliformis' should be attributed to the genus Besa as B. japonica and B. divarica, including B. divaricata f. ahnfeltioides. - (28 Mar 2021) - Wendy Guiry

General environment
This is a marine species.
