Leptodora Lilljeborg, 1861 is the type (single) genus of the family Leptodoridae Lilljeborg, 1861 of the gymnomeran order Haplopoda ; Sida Straus, 1820 is the type genus of the family Sididae, Baird 1850 of the ‘‘calyptomeran’’ order Ctenopoda . Among all cladocerans, AII of Leptodorosida gen. nov. is maximally similar with one of Leptodora , while general body shape is similar with sidids.
Diagnosis
Body elongated with expressed postero-dorsal angle. Distal extremity of head protruding anteriorly, posterior portion of head inflated. AII with proximal segment of endopod long and proximal segment of exopod of moderate length, second segment of exopod shorter than 3 + 4 segments. Each of segments 3–4 of endopod with a series of setae.
