A paedomorphic form type of , SARS, 1903 (Cladocera, Daphniidae) from Mongoliadge, leading to retrocurved shape of the head and a concavity of the dorsal shell margin. This excessive form type of the adult is a paedomorphic characteristic. It is assumed, that the retrocurved elongation of the head and the crescent-like shape of the valves are adaptations to a pelagic mode of

Is ephippial morphology a useful taxonomic descriptor in the Cladocera? An examination based on a stre distinguished on the basis of the following features: number of loculi, presence of bifid appendages, texture of dorsal ridge, texture of valve surface. The extent of the differences observed indicates that a species complex of . may be present in Australia, and suggests that ephippial morphology

Inter- and intraspecific variations in limb morphology of some south-east Australian cladocerans: Ims.d. in . adults (2.34 ± 0.07 mm) was 0.17–0.25 .m. I.s.d. increased with increasing body size for . and .. Variation in i.s.d. between nine adult cladoceran taxa (several of which coexisted) also was examined; significant differences did occur, but the size range was small (0.14 to 0.58 .m). The po

A Far East Moina, , Ishikawa, 1896 found in an Italian ricefieldattern of cladoceran species, characterized by the dominance of Moinidae in the early phase the rice cultivation (from May to July). In particular a species new for Italy, . Ishikawa, 1896, typical of Far East ricefields, was found; it was probably introduced into Italy with seeds and constitutes a
