A New Species

Over the last decade, the combination of biological surveys, genetic diversity assessments and systematic research has revealed a growing number of previously unrecognised vertebrate species endemic to the Australian Monsoonal Tropics. Here we describe a new species of saxicoline velvet gecko in the Oedura marmorata complex from Groote Eylandt, a large island off the eastern edge of the Top End region of the Northern Territory. Oedura nesos sp. nov. differs from all congeners in combination of moderate size, and aspects of tail morphology and colouration. It has not been reported from the nearby mainland regions (eastern Arnhem Land) suggesting it may be an insular endemic, although further survey work is required to confirm this. While Groote Eylandt is recognised as a contemporary ecological refuge for declining mammal species of northern Australia, newly detected endemic species suggest it may also be of significance as an evolutionary refuge for many taxa, especially those associated with sandstone escarpments.

AbstractHelopeltis pernicialis, a new species of bryocorine Miridae, is described from northern Australia, where it has become established as a serious pest of cultivated cashews, Anacardium occidentale (Anacardiaceae). Information on the biology and pest status of the bug is provided from studies conducted near Darwin, Northern Territory.

A New Species

A chromosomal analysis of gekkos of the Gehyra australis complex from the Alligator Rivers region of the Northern Territory indicates that those animals living on trees or human habitation have 2n=40 chromosomes, whereas those living on the rock outliers and cliffs of the Arnhem Land escarpment have 2n=42. A morphological analysis of these specimens shows that two distinct species are present: Gehyra australis and a new species, which is described below as Gehyra pamela.

Most records of Sminthopsis sp. and all records of Pseudomys calabyi are from gravelly hills with Eucalyplus dichromophloia and E. tintinnans woodland in Stage III of Kakadu National Park, Northern Territory. This habitat is distinct from that used by other small dasyurids and pseudomyine rodents of this region. For P. calabyi it may offer the attraction of prolonged availability of fallen grass seeds. Both taxa have vicariants in the Kimberley, a pattern resembling that for many vertebrate species pairs of the more isolated sandstone massifs of the Kimberley and Arnhem Land area.

A New Species

A new brittlestar species Macrophiothrix caenosa is described from Darwin, Northern Territory, Australia. It is common throughout tropical Australia and is also recorded from Japan and Singapore. It is distinguished from congeners by the combination of trapeziform dorsal arm plates, short multifid disc stumps, radial shields with stumps or rugose granules, dental plate shape, arrangement of dental papillae and distribution of ventral disc armament.

Intermittent Sampling

There has been marked recent decline in the terrestrial mammal fauna across much of northern Australia, with most documentation of such decline for lowland areas. Here we report changes in the assemblage of small mammals in a rugged sandstone environment (Nawurlandja, in Kakadu National Park) over intermittent sampling between 1977 and 2002. Four native mammal species were commonly recorded in the original sampling: sandstone antechinus (Pseudantechinus bilarni), northern quoll (Dasyurus hallucatus), Arnhem rock-rat (Zyzomys maini) and common rock-rat (Z. argurus). Trap success rates declined significantly for the northern quoll, Arnhem rock-rat and all species combined, but increased for the common rock-rat. Despite being recorded commonly in the initial (1977–79) study, no Arnhem rock-rats were recorded in the most recent (2002) sampling. Trap success rates for northern quoll declined by ~90% from 1977–79 to 2002. The reasons for change are not clear-cut. Notably, all sampling occurred before the arrival of cane toads (Rhinella marina), a factor that has caused severe decline in northern quoll numbers elsewhere. Fire was more frequent in the sampling area in the period preceding the 2002 sampling than it was in the period preceding the initial (1977–79) sampling, and this may have contributed to change in mammal abundance.

A New Species

Nymphaea kakaduensis C.B.Hellq., A.Leu & M.L.Moody (Nymphaeaceae) is described from Kakadu National Park, Northern Territory. This new species is endemic to the “Top End” of the Northern Territory and was formerly included in N. violacea Lehm. The distinct floral form of N. kakaduensis of having generally smaller flowers with blunt-tipped petals and different coloration than N. violacea instigated a genetic study of taxa from the region. The cpDNA trnL (UAA) - trnF (GAA) intergenic spacer region was sequenced from samples from across northern Australia and a haplotype network analysis was conducted. Plants from populations that had the distinct floral form of N. kakaduensis are found to be genetically distinct from N. violacea in northern Australia sharing 4 SNPs and a notable 23 bp indel in the cpDNA intergenic spacer region to support the morphological attributes and species designation.

A New Species

Morphological studies of Lechenaultia filiformis R.Br. have determined that more than one taxon is presently included under that name. We here recognise the suite of disjunct populations from north-east Queensland, north-east Northern Territory, New Guinea and the Moluccas as a new species, Lechenaultia peregrina R.W.Jobson & R.L.Barrett. This is the third tropical species of Lechenaultia currently recognised, however further studies are required to assess the status of about five additional entities in the Northern Territory and Western Australia currently included in L. filiformis s.l. Seed article morphology is critical for species delimitation in tropical Lechenaultia, but seed articles are often absent from collections, or only immature, as they fall quickly once ripe.

Magical Beliefs

This chapter shows that the history of black magic in modern times is a cosmopolitan drama. Human movement rapidly accelerated from the nineteenth century. People, goods, technologies, and ideas began crossing the earth at a dizzying rate. Travellers took their magical beliefs abroad and encountered new mysticisms when they got there. Empires regulated their colonial subjects in all sorts of ways, including how they dealt with witches. Witchcraft became more international, though at the same time it remained fundamentally rooted in local circumstances. This means that, to understand modern witchcraft, one must combine a global orientation with a local focus. And an excellent place for that local focus is a large island, lying on the eastern edge of the North Atlantic Ocean: Britain.
