Gammarus zagrosensis Zamanpoore, Poeckl, Grabowski & Schiemer, 2009 View in CoL

Gammarus zagrosensis Zamanpoore, Poeckl, Grabowski & Schiemer, 2009: 23 View in CoL View Cited Treatment –31, Figs. 2–5. Gammarus syriacus ( Stock et al., 1998: 206) View in CoL , 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 View FIGURE 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).
