Gammarus crinicaudatus ( Stock et al ., 1998 : 189 –195, Figs. 10–12), misidentified . Locus typicus. Village Belovo near Pazardzhik (Pazardzhik province), Bulgaria . Material examined. Many Specimens, Shahrestanak ( 36º08'N , 51º20'E ), Tehran Province, 1995, ( ZMA Crust. Amph. #?); many specimens, Gardane ye Cheri, May 2001 ( 32º10'N , 50º14'E ) ( ZUTC Amph. 2080); new material : three specimens, Hablerood river, Firuzkuh, September 2000 ( 35º45'N , 52º46'E ) ( FAIC 111289 ); many specimens, Amanabad, Mash'had (36˚10ʹN, 59˚40ʹE) ( FAIC 111288 ). Distribution. This species is widely distributed in fresh running waters in Iran , most frequently along a northwest-northeast axis in northern skirts of Alborz (Elburz) Mountains ( Stock et al. , 1998 ; Alizade-Eghtedar & Sari, 2007 ). Some populations are reaching southwards to the northern margins of Zagros ( Stock et al. , 1998 ; Ebrahimnezhad et al. , 2005 ; Khalaji-Pirbalouty & Sari, 2006 ) ( Fig. 1 ). Ecological notes. The species lives in habitats with slow water current and dense aquatic vegetation ( Karaman & Pinkster, 1977 ) having cold water (ca. 12ºC), at higher elevations (above 2200 m asl) ( Khalaji-Pirbalouty & Sari, 2004 ). Population from Amanabad inhabits a spring with water temperatures from 8 to 18ºC. Taxonomic remarks. Long setae on antenna 2 can be a source of confusion in differentiating of G. komareki from few Iranian species. In G. komareki the setation is more dense and distally curved ( Karaman & Pinkster, 1977, Fig. 33D ) if compared to G. crinicaudatus . In the latter species pereopod 4 and uropod 3 ( ibid. Figs. 33 O , K) are more setose than in G. komareki . Setation of antennae 2 in G. pretzmanni is dense and highly curled ( Mateus & Mateus, 1990, Fig. 2C ), but the species has very short setae (shorter than the spines) on anterior margin of pereopod 7. In G. parthicus anterior margin of pereopod 7 is bare as well ( Stock et al. , 1998 , Fig. 15c). Gammarus loeffleri , in contrast, has much longer setae on anterior of pereopod 7 ( Zamanpoore et al. , 2010a , Fig. 9C) than G. komareki .
