The known species of the genus Geckomima, a relatively robust, subarboreal member of the norabine grasshopper tribe Warramungini, are described, keyed, and their relationships discussed. Twelve species, brevicornis, lesueuri, handschini, brevirostris, gecko, drysdaleana, yampi, tindalei, pilbara, leopoldana, nepos, and arnhemana, are recognized (the last seven new) and two races within arnhemana. The genus is restricted to the Northern Territory and the northern half of Western Australia. G. handschini has an extensive distribution in the drier parts of the Northern Territory and adjacent Western Australia, while the remaining species occupy smaller areas to the north and west. All species are ostensibly allopatric, but all are probably in fact parapatric with their nearest neighbours.

The mistletoe flora of the tropical Kimberley region of Western Australia was studied over a 30-year period, with a particular emphasis on distributions, use of hosts and effects of fire. The results were compared with those of a similar study undertaken in the Pilbara, a more arid tropical region in the same State. The flora consisted of one genus with three species in the Santalaceae and five genera with 22 species (one with two varieties) in the Loranthaceae. Amyema was the largest genus in both regions. Four species are regarded as Kimberley endemics but two of them may also occur in the Northern Territory. Most species occurred in three or more of five Kimberley bioregions. However, six species were recorded only from the North Kimberley where they were all rare. Host records included 165 species from 33 families. Fabaceae (particularly Acacia) and Myrtaceae (particularly Eucalyptus and Corymbia) were the most important. The perfect dichotomy between species using fabaceous and myrtaceous hosts in the Pilbara was strong but imperfect in the Kimberley. Fire responses of two species were not observed. Two (perhaps three) taxa were able to resprout, whereas the remaining taxa were killed if scorched. Most species occurred, at least occasionally, in relatively fire-safe refugia. Nevertheless, fire is eroding distributions of many species and may be threatening some, particularly the rare North Kimberley species.

Two Component

A taxonomic analysis is presented of the closely related general Culmacris and Stiletta, in the morabine grasshopper tribe Warramungini. Culmacris is treated as comprising four species, orientalis, curvicercus, archaica, and diversa (the last two new) and 13 races within diversa. These taxa occupy a mosaic of 16 non-sympatric, almost certainly parapatric, ranges covering between them a large part of the northern half of Australia. The 13 races of diversa are diagnosed primarily on karyotypic characters following White's findings in a companion paper; they are grouped into 'race groups' and one ungrouped race, on characters of the male genitalia. Stiletta, with two probably parapatric species nitida and mesai, the latter new and the former with two component races, occupies a small area straddling the border of Western Australia and the Northern Territory in the region of the Ord and Victoria Rivers. It is sympatric with Culmacris in the Victoria River area. Keys to the genera of Warramungini and the species of Culmacris and Stiletta are provided.

A New Species

We describe a small hylid frog species with a highly distinctive tadpole from the Kimberley region of northern Western Australia. The new taxon is morphologically very similar to Litoria meiriana but can be differentiated using a combination of adult and larval morphology and male calls. Tadpoles of the new taxon can be readily differentiated from those of L. meiriana by their unique black, gold and red pigment patterns and the continuous papillary border around the oral disc. Advertisement calls of L. aurifera sp. nov. are longer, have more pulses, have more marked frequency modulation and are produced at a lower rate than those of L. meiriana. Litoria aurifera sp. nov. is only known from locations up to about 100 km south of the Prince Regent River and is associated with small creeks on massive sandstone escarpments, while L. meiriana is widespread in escarpments across northern Western Australia and the northern part of the Northern Territory.

Head Morphology

The structural organisation of the sperm head of individuals included within the species Pseudomys delicatulus, and P. patrius, which has recently been separated from P. delicatulus, is detailed here. P. patrius has a sperm type with three hooks - a feature shared with most other species of Pseudomys including all three other pebble-mound mice. By contrast, P. delicatulus has a very different sperm type that lacks the three hooks and in this species two morphotypes appear to be present. One is highly variable, generally pear-shaped with a basal attachment of the sperm tail, and is present in individuals which occur on the mainland of the Northern Territory and Western Australia. The other, which is present in individuals in Queensland and on West Island and Groote Eylandt off the north coast of Northern Territory, is bilaterally flattened with a single, attenuated, blunt apical hook and tail attached to the lower concave surface. These results (1) support the recent separation of P. patrius from P. delicatulus and, (2) suggest the presence of a cryptic species or subspecies within Pseudomys delicatulus as presently constituted.

Northern Territory, and possibly parts of the Pilbara, have been ‘seeded’ with virus which could result in epizootic activity when appropriate environmental conditions occur. Our conclusions could have important health implications as the population in north-western Australia increases through intensive agriculture, mining, service industries and tourism and, in the longer term, through possible effects of climate change (Mackenzie et al. 1993b; Lindsay and Mackenzie 1997). Furthermore, increased virus activity could be exacerbated as new irrigation areas are developed in the Wyndham–East Kimberley shire and the adjacent part of the Northern Territory. Finally, there is little doubt that the profound ecological changes resulting from the establishment of the Ord River irrigation area have provided ideal conditions for increased arboviral activity. These conditions are also suitable for other exotic arboviruses, such as Japanese encephalitis and chikungunya viruses, and exotic mosquito vectors, such as Aedes albopictus. Indeed an unusual strain of MVE has been isolated from the Ord River area, which was believed to have been introduced from the Indonesian archipelago (Mackenzie et al. 1991). Further-more, the recent incursion of Japanese encephalitis virus into islands in the Torres Strait and Cape York, and its possible enzootic presence in the south of Papua New Guinea, provide additional cause for concern. It is therefore essential that monitoring and surveillance of mosquitoes and arboviruses is continued so that exotic virus or vector incursions can be rapidly detected. Acknowledgments We would like to thank our many colleagues who have contributed to these studies of MVE virus activity in the north-west of Western Australia. We would also like to acknowledge the support of the Health Department of Western Australia and the National Health and Medical Research Council, and the Commonwealth Department of Health.

The Impact

The long history of Asian contact with Australian Aborigines began with the early links with seafarers, Makassan trepang gatherers and even Chinese contact, which occurred in northern Australia. Later contact through the pearling industry in the Northern Territory and Kimberley, Western Australia, involved Filipinos (Manilamen), Malays, Indonesians, Chinese and Japanese. Europeans on the coastal areas of northern Australia depended on the work of indentured Asians and local Aborigines for the development and success of these industries. The birth of the Australian Federation also marked the beginning of the “White Australia Policy” designed to keep non-Europeans from settling in Australia. The presence of Asians in the north had a significant impact on state legislation controlling Aborigines in Western Australia in the first half of the 20th century, with implications to the present. Oral and archival evidence bears testimony to the brutality with which this legislation was pursued and its impact on the lives of Aboriginal people.

Sporadic Cases

Bovine ephemeral fever is an important viral disease of cattle in Australia. The disease occurred each year, principally in summer and autumn, between 1981 and 1985. Queensland and the northern half of New South Wales were areas of greatest activity with only sporadic cases being reported from the Northern Territory and the northern third of Western Australia. Since 1981, the disease has been endemic in an extensive area of eastern Australia and has tended to occur in widely scattered outbreaks rather than the north-south advancing wave form of the epidemics of 1936-37, 1967-68, 1970-71 and 1972-74. The southernmost outbreaks between 1981 and 1985 were well within the limits of these earlier epidemics. The pattern of disease appears to have become seasonally endemic rather than periodically endemic in the northern two-thirds of eastern Australia. Ephemeral fever was not recorded in Victoria, Tasmania, South Australia or the southern part of Western Australia between 1981 and 1985

Sharks and rays are a global conservation concern with an increasing number of species considered at risk of extinction, mostly due to overfishing. Although the recreational harvest of sharks and rays is poorly documented and generally minimal, it can be comparable to the commercial harvest. In this study, we quantified the recreational harvest of sharks and rays in Western Australia, a region with a marine coastline greater than 20,000 km. A total of 33 species/taxonomic groups were identified, with the harvest dominated by dusky and bronze whalers, blacktip reef sharks, gummy sharks, Port Jackson sharks, wobbegongs, and rays and skates. Eighty-five percent of individuals were released with an unknown status (alive or dead). We found a latitudinal gradient of species composition, with tropical and subtropical species of the genus Carcharhinus dominating in the north and temperate species from a range of families dominating in the south. Overall, our findings showed that the recreational harvest was negligible when compared with commercial landings.

Significant Difference

Xavier Herbert published his bestseller Capricornia in 1938, following two periods spent in the Northern Territory. His next major work, Poor Fellow My Country (1975), was not published until thirty-seven years later, but was also set in the north during the 1930s. One significant difference between the two novels is that by 1975 photo-journalism had become a significant force for influencing public opinion and reforming Aboriginal policy. Herbert’s novel, centring upon Prindy as vulnerable Aboriginal child, marks a sea change in perceptions of Aboriginal people and their place in Australian society, and a radical shift toward use of photography as a means of revealing the violation of human rights after World War II. In this article I review Herbert’s visual narrative strategies in the context of debates about this key historical shift and the growing impact of photography in human rights campaigns. I argue that Poor Fellow My Country should be seen as a textual re-enactment, set in Herbert’s and the nation’s past, yet coloured by more recent social changes that were facilitated and communicated through the camera’s lens. Like all re-enactments, it is written in the past conditional: it asks, what if things had been different? It poses a profound challenge to the state project of scientific modernity that was the Northern Territory over the first decades of the twentieth century.
