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.

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.

Basic Biology

There is a high rate of recent species discovery in remote regions of northern Australia, especially for amphibians and reptiles. The Wessel Islands, located in the northeastern corner of the Northern Territory, has recently been identified as a region of high species and phylogenetic endemism based on samples collected during the sole reptile and amphibian survey there in 1993. Using a phylogenetic approach, we describe a new, evolutionarily distinct species of Uperoleia endemic to the Wessel Islands. This description is based on three specimens, one female and two juveniles, which represent the only confirmed vouchers of the species. Due to the low number of specimens, this new species cannot be diagnosed morphologically from other closely related Uperoleia, and nothing is currently known about the mating call or basic biology. The discovery of this species provides further evidence for the islands’ importance as an area of endemism and identifies an urgent need for further surveys to document the unique biological diversity of the Wessel Islands.

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.

A New Species

The taxonomic status of Acacia holosericea A. CUM. ex Don is re-appraised in the light of recent isozyme, chromosome and field studies, as well as from a critical examination of specimens at BM, BRI, K, DNA and PERTH. Accordingly, A. holosericea, as traditionally defined, is now regarded as comprising three distinct species, each corresponding to a dierent level of ploidy. Acacia holosericea A. Cum. ex Don (tetraploid) is widespread, principally in tropical/subtropical areas of Western Australia, the Northern Territory and Queensland. Acacia neurocarpa A. Cunn. ex Hook. (diploid), occurs in tropical/subtropical Western Australia and the Northern Temtory and until now has been regarded as conspecific with A. holosericea. Acacia colei Mash & Thomson (hexaploid) is described as a new species which appears to have evolved as an allopolyploid hybrid between A. neurocarpa and A. cowleana (tetraploid). It is widespread and common in subtropical/arid Western Australia, the Northern Territory and Queensland. These four species are illustrated, mapped and their principal discriminating features given in tabular form and in a key. Acacia holosericea is neotypified to exclude A. neurocarpa, and A. neurocarpa is lectotypified to exclude A. dunnii (Maiden) Turrill.

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.
