A list of macroinvertebrate species recorded in the zoobenthos in Lake Sevan in 2007 and 2010 is presented. The list includes 38 species, 14 of which have been found in the lake for the first time. Chironomid larvae and pupae are the most diverse (27 species) in the macrozoobenthos of the lake. In Bolshoi Sevan, the maximum biomass of macrozoobenthos (24.82 g/m(2)) was recorded in the sublittoral; in Malyi Sevan the maximum biomass (14.31 g/m(2)) was recorded in the profundal. In 2010 chironomids dominated by biomass in the sublittoral (48.9 and 60.3%, respectively). The benthos in the littoral was dominated by oligochaetes (50.2%).
