6. Marionina . Found in two sampling localities: small stream at the outlet of the lake and limnocrenes in the bed of temporary streams. Found in stony-pebbly soils. Here, Enchytraeidae oligochaetes dominate; in addition the chironomids of Diamesa spp. , Cricotopus spp. and Metriocnemus gr. fuscipes are sometimes seen.

Moss-associated macrobenthic communities

These communities are the most characteristic for moss undergrowth of low current and standing water bodies, and, to a lesser extent for other solid substrates in same reservoirs (rich in moss). Genera of chironomid Orthocladiinae dominate in these communities.
