bicolor, Tigoma Girard [C. F.] 1856:206 [42] [Proceedings of the Academy of Natural Sciences of Philadelphia v. 8; ref. 1810] Klamath Lake, Oregon, U.S.A. Syntypes: USNM 234 (3, plus one pair pharyngeal arches as # 2788). Type catalog: Gilbert 1998:49 [ref. 23395]. Jordan & Evermann 1896:232 [ref. 2443] qualify as first revisers, selecting Tigoma bicolor over Cheonda coerulea (see Bailey & Uyeno 1964:238 [ref. 23390]). Bailey & Uyeno 1964:238 [ref. 23390] serve as first revisers selecting Algansea bicolor over Tigoma bicolor only when both are in Gila; therefore, Cheonda coerulea was reinstated. As this name was used as valid for more than 50 years, it is now retained even when in Klamathella for the sake of stability. •Synonym of Gila coerulea (Girard 1856) -- (Bailey & Uyeno 1964:239 [ref. 23390], Gilbert 1998:49 [ref. 23395], Nelson et al. 2004:70 [ref. 27807]). Current status: Synonym of Gila coerulea (Girard 1856). Leuciscidae: Laviniinae. Habitat: freshwater.
