08AB35C1A321506E8D660B41B5885AF5.taxon	etymology	Etymology. The specific name is derived from the Japanese noun Sinelobus kisui (brackish water), referring to the habitat of this species, and also referable to the Japanese name Kisui-tanaisu, proposed by Ariyama and Ohtani (1990) for this species in the Shin Yodo River, Osaka.	en	Hirano, Kyoko, Kakui, Keiichi (2022): A new brackish tanaidacean, Sinelobus kisui sp. nov.
