Gammarus lordeganensis Khalaji-Pirbalouty & Sari, 2004

Gammarus lordeganensis Khalaji-Pirbalouty & Sari, 2004: 2430 –2435, Figs. 2–4.

Locus typicus. Barme-Lordegan Spring (31˚30ʹN, 50˚49ʹE), Lordegan, Chaharmahal Va Bakhtyari province.

Material examined. Holotype and paratypes, Aug. 2000 ( ZUTC amph. 2060).

Distribution. Apparently an endemic species, reported so far from only two springs (31˚34ʹN, 51˚13ʹE) in central Zagros ( Fig. 1 ).

Ecological notes. This species is found exclusively in mountain springs at ca. 1600 m asl with temperatures of ca. 12ºC.

Taxonomic remarks. There are several similarities between this species and G. pseudosyriacus , especially in setation of all body parts, but with presence of the flat dorsal surface of urosomites one can distinguish G. lordeganensis from the latter species. G. lordeganensis is also very similar to G. lacustris , however it differs from the latter with first coxal plate in gnathopod 1 extended antero-distally ( Khalaji-Pirbalouty & Sari, 2004, Fig. 3 GN1) and with more dense setation of uropod 3 (ibid., Fig. 2 U3).
