“…Beside the new species, two other species already known from Australia, are transferred to the genus Riocypris. The second species dealing with in this paper is Cyprinotus cingalensis Brady, 1886, described from Southeast Asia (Brady 1886a), but latter found in Queensland (Sars 1889). After finding great variability in populations collected from the Pilbara region, the following species are synonymized with it: C. dahli Sars, 1897; kimberleyensis McKenzie, 1966 andC.…”

“…In fact, the armature details of P1-P4 are not known for most diaptomid species, though, occasionally, interesting modifications can be witnessed. For example, all the outer spines of exopodal segments of P2-P4 are enlarged and spatulate in the species of Megadiaptomus Kiefer, 1936c(see Ranga Reddy, 1990, the outer spine of first exopodal segment of P1 is extraordinarily long in Arctodiaptomus (Rhabodiaptomus) michaeli Ranga Reddy, Balkhi, andYousuf, 1999 (see Ranga Reddy et al, 1999), and the third inner seta of the third exopodal segment of P4 is very long with modified setules in Tropodiaptomus orientalis (Brady, 1886) (Ranga Reddy, unpublished).…”

“…Neodiaptomu prateek was found co-existing simultaneously with four species of the genus Heliodiaptomus Kiefer, 1932a: H. cinctus (Gurney, 1907), H. contortus (Gurney, 1907), H. viduus (Gurney, 1916), and H. elegans Kiefer, 1935a, two species of the genus Neodiaptomus: N. schmackeri and N. meggitti, and one sole representative of the genus Tropodiaptomus: T. orientalis (Brady, 1886). Numerically, H. contortus was the most dominant species, followed by H. cinctus, whereas the other species were represented almost as strays.…”

A B S T R A C TNeodiaptomus prateek n. sp. is described based on a plankton sample collected from Deepor Beel, a floodplain lake in the north-eastern, Indian state of Assam, which falls within the key biodiversity area of the Indo-Burma Hotspot. The new species fulfils all the principal criteria of the genus Neodiaptomus Kiefer, 1932, as revised by Kiefer (1939). It has, however, a spectacular autapomorphic feature, which is perhaps unparalleled in Diaptomidae as a whole -a massive coxal plate ending in a thumb-like spinulose structure on the caudal surface of the male left P5. The new taxon also has two homoplastic characters that are hitherto unknown within the genus: the female fourth pediger has a prominent mid-dorsal process, and the third endopodal segment of P2-P4 has six instead of seven setae, the proximal outer seta being absent. The affinities of the new species with its congeners are discussed. Furthermore, the generic assignment of all the 13 species of Neodiaptomus listed in the latest World Copepoda database (Walter, 2012) is critically reviewed. Of these, five species are recognised as valid, six are relegated to species inquirendae, and one each is a nomen dubium and a synonym. Two lineage groups are recognised within the genus, one belonging to Southeast Asia and the other mostly confined to India. Surprisingly, the new species was accompanied by a record number of seven other diaptomid species in the same sample; the probable biogeographic and ecological implications of this high species richness are briefly discussed.

The freshwater Cladocera of Sri Lanka has been revised based on the study of over 700 zooplankton samples collected from all habitat types during 1965-1980 . The cladoceran fauna is represented by six families ; members of the families Polyphemidae, Leptodoridae and Holopedidae are absent . The common temperate genus Daphnia is rare .Sixty-two species have been recorded from Sri Lanka . Of these, five are new records . Remarks on a few species are given with illustrations . The distribution of Cladocera in different types of habitats is discussed . The greatest species diversity was found in ponds . The Sri Lankan fauna is numerically and in species diversity typical of tropical cladoceran fauna . It resembles the southern Indian fauna very closely except for the absence in Sri Lanka of the genera Acroperus and Camptocercus .
