A new species of intertidal sesarmid crab, Parasesarma hartogi, is described from the upper mangrove zone in Shark Bay, Western Australia. It differs from its four closest relatives in the P. plictatum species-complex by being broader between the epibranchial angles than between the exorbital angles; showing differences in the number and form of the dorsal dactylar tubercles of the male cheliped, a relatively broader gape between the fingers of the adult male chelae, proportions and shape of the male abdomen, and shape of the male first gonopod.

Ongoing surveys and systematic work focused on the Pilbara region in Western Australia have revealed the existence of numerous unrecognized species of reptiles. Here we describe Underwoodisaurus seorsus sp. nov., a new species similar to U. milii, but differing in its relatively plain dorsal and head patterns with only sparsely scattered pale tubercles, a much more gracile build, including longer snout, limbs and digits, smaller and more numerous fine scales on the dorsum, and the enlarged tubercles on the tail tending not to form transverse rows. The new species is known from few specimens and has only been encountered at mid elevations in the Hamersley Ranges, widely separated from the closest populations of U. milii in the northern Goldfields and Shark Bay in Western Australia. Given its rarity and small (potentially relictual) distribution this species may be of conservation concern.

Specimens previously identified as Macrophthalmus japonicus from Shark Bay, Western Australia, are described as a new species, M. pistrosinus. The new species differs both in behaviour and morphology from its closest relatives, particularly in characters such as proportions of male abdomens, setation patterns of claws, carapace dentition and leg morphology.

AbstractA new species of spider crab, Acanthonyx formosa, is described from seaweed beds in Taiwan. The species is allied to A. euryseroche Griffin & Tranter, 1986, from western Australia, but differs markedly in the proportions of the adult male rostrum, and in the structure of the hepatic tooth, the third maxilliped, the adult male chela, and the male first pleopod. Acanthonyx formosa is only the second species of Acanthonyx known from the Pacific, the other being A. simplex Dana, 1852, from Hawaii. Une nouvelle espece de crabe, Acanthonyx formosa, est decrite de lits d'algues, a Taiwan. L'espece est apparentee a A. euryseroche Griffin & Tranter, 1986, d'Australie occidentale, mais en differe nettement dans les proportions du rostre du male adulte, la structure de la dent hepatique, le troisieme maxillipede, la pince du male adulte et le premier pleopode male. Acanthonyx formosa n'est que la seconde espece du genre connue du Pacifique, la premiere etant A. simplex Dana, 1852, des Hawa.

Seven species of freshwater crabs from three families are recorded from and around the Danum Valley Conservation Area in Sabah, Malaysian Borneo: Thelphusulacapillodigitus sp. n., Thelphusuladicerophilus Ng & Stuebing, 1990, Arachnothelphusaterrapes Ng, 1991, Terrathelphusasecula Ng & Tan, 2015, Parathelphusavalida Ng & Goh, 1987 (new record) (Gecarcinucidae); Isolapotamoningeri Ng & Tan, 1998 (Potamidae); and Geosesarmadanumense Ng, 2002 (Sesarmidae). The new species of Thelphusula Bott, 1979, can be distinguished from all congeners by a unique combination of morphological features, most notably the presence of dense patches of short setae on the fingers of the adult male chelipeds, as well as the structure of the male first gonopod. Arachnothelphusaterrapes is confirmed to be a phytotelm species. A key to all species in the conservation area is provided.
