2708D0066D3E471CE123FC1EFC081709.taxon	etymology	Etymology. The subspecies name is derived from the name of the type locality, Aznav. Habitat. Specimens were sampled from a slow running limnocrene spring with dense submerse aquatic plants in Aznav County (Khalkhal-Ardabil). Some of the physicochemical characters were as follows: salinity: 0.2 ppt; pH: 7.2; electrical conductivity: 310 µS 25 ° C; water temperature: 11 ° C; maximum depth: 130 cm. Variability. Among the 20 specimens, the number of flagellar segments of antenna 1 varied from 13 to 21. We never observed minute, ovoid eyes among the paratype specimens. In general, eyes were as long as or slightly longer than the diameter of the first peduncle segment of antenna 1. The length and number of the setae along the anterior margins of pereopods 5 to 7 were variable in males; some of them have more setose pereopods 5 – 7 than those of the holotype.	en	Özbek, Murat, Received, Hamidreza Rasouli, Online, Published (2014): Gammarus komareki aznavensis subsp. nov., a new amphipod subspecies from Iran (Amphipoda: Gammaridae).
