Taxonomic review of freshwater Gammarus (Crustacea: Amphipoda) from Iran Author Zamanpoore, Mehrdad Author Grabowski, Michal Author Poeckl, Manfred Author Schiemer, Friedrich text Zootaxa 2011 3140 1 14 journal article 45727 10.5281/zenodo.205631 d203873a-602b-4c12-9c8f-17c51609cf74 1175-5326 205631 Gammarus zagrosensis Zamanpoore, Poeckl, Grabowski & Schiemer, 2009 Gammarus zagrosensis Zamanpoore, Poeckl, Grabowski & Schiemer, 2009 : 23 –31, Figs. 2–5. Gammarus syriacus ( Stock et al. , 1998 : 206 ) , misidentified . Locus typicus. Vezge-Morad spring ( 30°13´N , 51°58´E ), S of Sepidan, Fars Province. Material examined. Holotype ( ZMA Crust. Amph. 206052). Paratypes : Khani Varg spring, 4 km S of Sepidan ( 30°12´N , 51°59´E ) ( FAIC 111053 -1); Baraghan spring, 5 km SE of Sepidan ( 30°15´N , 51°59´E ) ( FAIC 111238 , FAIC 111239 ); Sheshpeer (spring brook), 10 km SE of Sepidan ( 30°15´N , 52°03´E ) ( FAIC 111105 -1). Misidentified as G. syriacus . Non-type specimens, Borghan (Baraghan) spring, ( 30°15´N , 51°59´E ) ( ZMA Crust. Amph. #?). Distribution. An endemic species, inhabiting almost the same geographic area in the lower Central Zagros as G. sepidannus ( Fig. 1 ). Ecological notes. Gammarus zagrosensis is sympatric with G. sepidannus , so ecological features of their habitats are mostly similar. In the montane ( 1991 – 2350 m asl, Mean = 2196 m , SD = 85) and cold region of lower Central Zagros, the water temperature measured from 10 to 13ºC over the year (Mean = 12 ºC, SD = 0.8), with electric conductivities of 180 – 410 μS/cm (Mean = 249 μS/cm, SD = 61). Taxonomic remarks. With the relatively short setation of pereopod 5–7, the species might seem similar to G. syriacus , but features quite clearly separating it from the latter species include: long setae on inferior margin of epimeral plates 1–3 ( Zamanpoore et al. , 2009 , Fig. 4E), slightly pointed epimeral plates 2 and 3 ( ibid. ), long setae in postero-distal corner of pereopod 6 and 7 ( ibid. , Figs. 4A–C), longer antennal gland cone ( ibid. , Fig. 2C). Misidentifications. See relevant section under G. pseudosyriacus .
