Ephippial female ( Fig. 3A View FIGURE 3 ). General body shape and appendages of ephippial female appearing similar to those of parthenogenetic female (Fig. A). Dorsal portion of body in ephippial female transformed into ephippium, clearly bordered from rest of body. In lateral view, ephippium narrowing posteriorly. Dorsal margin slightly convex to almost straight; ventral margin regularly curved from posteroventral to anteroventral angle. Depression along dorsum separating two halves of ephippium well-visible.

Antenna I ( Fig 3F View FIGURE 3 ) long, straight, covered by prominent small stiff setae. Antennular sensory seta long, arising subdistally from antennular body. Male seta especially robust, located in distal portion of antennular body and three times longer than this. Nine terminal aesthetascs on opposite side to antennular sensory seta.

Limb I ( Fig. 3G View FIGURE 3 ) with large, curved copulatory hook. ODL (exopodite) with two setae, one being especially long, bi-segmented, distal portion covered by fine short denticles. IDL (endite 5) additionally with short seta of unknown homology. Additional seta also located near anterior seta 1.

Endite 4 with single anterior stiff long seta unilaterally armed distally with short setulae, and single posterior soft seta ( Fig. 3H View FIGURE 3 : c). Endite 3 with single soft seta. Endite 2 with single anterior stiff seta (represented by small sensillum), single posterior soft seta ( Fig. 3H View FIGURE 3 : d) and small seta of unknown homology. Gnathobase (or endite 1) similar to parthenogenetic female. Sexual dimorphism in structure of limb II in C. quadrangula present: anterior seta near posterior seta c in female represented by small stiff seta, as relatively long in male; endite 3 with short stiff seta in female, with relatively long, soft seta in male. Sexual dimorphism in structure of limb II previously found in some species of Daphnia and Simocephalus (see Kotov 2013).

Size. Adult parthenogenetic females up to 1.2 mm in length; ephippial females up to 0.60 mm in length; adult males up to 0.53 mm in length.

Variability. No significant variability was found in studied individuals from Denmark.

Distribution and ecology. Ceriodaphnia quadrangula sensu lato has been cited from all biogeographical regions: Palaearctic, Nearctic, Neotropical, Afrotropical, Oriental and Australasian zones ( Kotov et al. 2013). However, in the frame of the non-cosmopolitanism concept in the cladoceran distributions, it is most likely, that the distribution of C. quadrangula sensu stricto is restricted to the western Palaearctic (mainly Northern and Central Europe and European part of Russia).

Ceriodaphnia quadrangula is mainly planktonic and characteristic of large and medium-sized lakes with low mineralized and oligo-mesotrophic waters.
