Short description. The head is rectangular to nearly round in shape. A large eye is present, near the ventral margin of the head. The second antenna is long which bifurcates to a dorsal and ventral swimming setae. The broad free flap at the postero-ventral margin bears both feathered and naked setae; postero-ventral margin contains ungrouped marginal spines. The postabdominal claw bears 3 spines, with short proximal spine and the long distal spine. The morphological characteristics concur with the descriptions and illustrations provided by Fernando (1992), Dumont and Negrea (2002) and Pascual et al. (2014).

Ecological distribution. Diaphanosoma sarsi is present in lakes, rivers, pools, and swamps. This fast swimmer cladoceran inhabits the pelagic area and can survive variety of water environmental conditions (i.e. trophic status and temperature) ( Rizo et al. 2017).
