Integrated molecular and morphological studies of newly collected and curated specimens of the genus Caridina from the Atherton Tablelands, Wet Tropics World Heritage Area in north–eastern Queensland, Australia indicated the presence of an undescribed species belonging to the Caridina zebra Short 1993 complex. This species is somewhat intermediate, although distinct on the basis of molecular data and morphology, from two known sympatric species, Caridina zebra and C. confusa Choy & Marshall 1997, and an allopatric species, C. spinula Choy & Marshall 1997, from the Cape York Peninsula, about 500 km north. It is described here as a new species, C. malanda sp. nov., and compared with similar congeners. A key for the identification of the species, as well as notes on its distribution, ecology, and conservation, are provided.

A new species, Balbaroo fangaroo, of balbarine kangaroo is described from the freshwater limestone deposits at Riversleigh northern Australia. The type specimens include two partial skulls which reveal hitherto unknown characters of Balbarinae and provide new evidence relevant to the resolution of the phylogenetic affinities of Balbarinae. A number of the newly-revealed characters e.g., squamosal-frontal contact on the walls of the neurocranium, are argued as being plesiomorphic for Macropodoidea.Hypertrophied upper canines which occur in the paratype, have never previously been recorded in kangaroos and represent an example of evolutionary convergence between these herbivorous marsupials and ungulate eutherians.

A partial skeleton (including both skull and postcranium) and referred dental material attributable to a new species of Oligo-Miocene kangaroo, Nambaroo gillespieae, are described from the Riversleigh World Heritage Area, northwestern Queensland, Australia. The holotype specimen is one of the oldest articulated fossil kangaroo skeletons yet discovered and includes the first postcranial material definitively attributable to the extinct family Balbaridae. Functional-adaptive analysis (including comparisons with modern taxa) of the hindlimb and pedal elements suggests consistent use of quadrupedal progression rather than true hopping. Robust forelimbs and an opposable first pedal digit (lost in most macropodoids) might also indicate limited climbing ability. Cladistic analysis of 104 discrete cranio-dental and postcranial characters coded for 25 ingroup and one outgroup taxon places N. gillespieae in a plesiomorphic sister clade (also containing other Balbarids and the propleopine Ekaltadeta ima) to all other macropodoids. This result supports recent revisions to the classification of kangaroos, which recognize Balbaridae as the most basal macropodoid family-level taxon.

The amphipod genus Sebadexius Ledoyer, 1984 (New Caledonia) is reviewed, based on new material from Cebu in The Philippines. Some characters are re-interpreted, and a new species, Sebadexius cebuense, is described.
