Gammarus paricrenatus Stock, Mirzajani, Vonk, Naderi & Kiabi, 1998

Gammarus paricrenatus Stock, Mirzajani, Vonk, Naderi & Kiabi, 1998: 206 –210, Figs. 21–23.

Locus typicus. Ghoree-Gol wetland (37˚26ʹN, 46˚40ʹE), Tabriz, East Azarbaijan Province.

Material examined. Six female paratypes ( ZMA Crust. Amph. 201952).

Distribution. An endemic species found in only one locality – Goree-Gol wetlands in west Alborz ( Fig. 1 ) ( Stock et al., 1998; Alizade-Eghtedar & Sari, 2007).

Ecological notes. No ecological data available.

Taxonomic remarks. Described based on only female holotype and paratypes, this species is clearly recognizable from other Iranian gammarids, especially upon the crenulate and setose postero-dorsal margin of its pleosomites ( Stock et al. 1998, Fig. 21b), unique pattern of antenna 2 setation (scarce but long setae on peduncle segments 4 and 5 – longer than the width of the segments, short setae on the flagellum), and long antennal gland cone – longer than the length of the third peduncle segment (ibid., Fig. 21D).
