Rivers flowing into the Seto Inland Sea in Honshu, Shikoku, and Kyushu, and rivers flowing into the Japan Sea in Honshu: Kyoto, Osaka, Wakayama, Hyogo, Okayama, Hiroshima, Yamaguchi, Kagawa, Tokushima, Ehime, and Fukuoka Prefectures (Saitoh & Aizawa 1987; Nakajima et al. 2008). Habitat and biology. This species inhabits sandy-mud bottoms of the middle and lower reaches of rivers. Saitoh (1990) described the spawning ecology of this species as the middle form of Cobitis striata.	en	Nakajima, Jun (2012): Taxonomic study of the Cobitis striata complex (Cypriniformes, Cobitidae) in Japan.

03CBD358FF96FFABF3D7574FFD44FECB.taxon	discussion	Remarks. Although this loach had been previously described as a subspecies of C. taenia Linnaeus, 1758, some recent genetic analysis refuted this designation (Šlechtová et al. 2008; Nakajima et al. 2011 a). It has been confused what is the true C. striata described by Ikeda (1936) because the original description of this loach has ambiguous information on the type locality, and the type series is missing and feared lost (Saitoh & Aizawa 1987). However, the author, Dr. Hyoji Ikeda, had stated that the type locality of C. striata is ‘ near Takamatsu, Kagawa’ in his other literature (Okada & Ikeda 1939; Aoyagi 1957) (Ikeda and Aoyagi are names of the same person). The results obtained in my field and literature surveys confirm that there is only one species, Cobitis sp. 3 subsp. 1 (sensu Nakajima et al. 2012), near this type locality. In addition, the description of C. striata is consistent with the morphological characters of Cobitis sp. 3 subsp. 1. Therefore, I conclude that C. striata Ikeda, 1936 is identical to Cobitis sp. 3 subsp. 1. The genetic features have been already reported by Kitagawa et al. (2005) and Saitoh et al. (2010).

It points out that the decline of the subspecies has been attributed to river improvement and urbanization (Saitoh 1989, 2005).
