Comments. Morphology of the studied specimens ( Fig. 11 A–D View FIGURE 11. A – D ) completely agrees with the recent redescription of the species (Sinev, 2009 b).

Distribution. It is distributed from North Canada (Chengalath, 1982) to North Mexico (Elías-Gutiérrez, 1997). According to Chengalath (1982), it is a eurybiotic species, distributed in different types of lakes, including those with brackish water. An interesting feature of A. circumfimbriata   is its ability to inhabit streams. In Indiana it is one of four most common species of Cladocera   in such habitats ( Vila 1989). In Aguascalientes, it is found in the dry and temperate regions, but one locality, a pond beside Mesa Montoro, Calvillo, is to close to the subtropical zone.
