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.

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

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.

A New Species

A new tribe of the Conocephalinae, Armadillagraeciini Rentz, Su, Ueshima is described to include three known Australiangenera: Armadillagraecia, Kapalgagraecia and Lichenagraecia gen. nov. Lichenagraecia gen. nov. is the eastern repre-sentative of the tribe, the others from the Northern Territory, northern Western Australia and western Queensland. Threenew genera in the tribe Agraeciini are described from the rainforests of north-eastern Queensland, Australia. Ingrischa-graecia gen. nov. is known from a single species, I. iterika sp. nov. Emeraldagraecia gen. nov. is known from two spe-cies, E. munggarifrons and E. windsorana spp. nov. Miniagraecia gen. nov. is described from two species: M. milyali andM. goorijupa spp. nov. In the Listroscelidinae; Requenini, a new species of the previously monotypic genus Xingbaoia,X. irvineorum sp. nov. is described from two localities in peril from repeated prescribed burning. Distribution maps, keys, measurements, song patterns and cytological observations are provided for most species.

ABSTRACT A previously unknown chemolithoautotrophic arsenite-oxidizing bacterium has been isolated from a gold mine in the Northern Territory of Australia. The organism, designated NT-26, was found to be a gram-negative motile rod with two subterminal flagella. In a minimal medium containing only arsenite as the electron donor (5 mM), oxygen as the electron acceptor, and carbon dioxide-bicarbonate as the carbon source, the doubling time for chemolithoautotrophic growth was 7.6 h. Arsenite oxidation was found to be catalyzed by a periplasmic arsenite oxidase (optimum pH, 5.5). Based upon 16S rDNA phylogenetic sequence analysis, NT-26 belongs to theAgrobacterium/Rhizobium branch of the α-Proteobacteria and may represent a new species. This recently discovered organism is the most rapidly growing chemolithoautotrophic arsenite oxidizer known.
