Two only partially known species of the family Gammaridae (Crustacea Amphipoda), Gammarus werneri (S. Karaman 1934) and Gammarus paraorientalis G. Kar. (new comb.) are treated. Rivulogammarus kesslerianus werneri ssp. n. has been shortly described by S. Karaman (1934) from Iznik (Asia Minor, NE Turkey) and later considered synonym of Gammarus balcanicus Schäferna 1922 (G. Karaman, 2003).Based on detailed study of holotype and one more recent sample of the same species from Iznik, this species is redescribed, figured and elevated to the species rank, Gammarus werneri (S. Karaman, 1934), belonging to Gammarus balcanicus Complex,Rivulogammarus balcanicus orientalis ssp. n. has been described by S. Karaman (1934) from Derbend [eastern site of Erdschias- dag (=Erciyas-dagi), Asia Minor (Turkey)]. Recently this species was redescribed and figured as distinct species, Gammarus orientalis (S. Karaman, 1934) from type locality and adjacent localities (G. Karaman, 2017). The new study showed that the name Gammarus orientalis is “nomen preoccupatum”, because the species under the same name has been described by Dana (1852) from Sundai, and new name for G. orientalis from Iznik is proposed, Gammarus paraorientalis G. Kar. (new name).
