Distinguishing Character

This taxon was recognised in Australian mangrove assemblages as Avicennia oficinalis L., which is commonly found in Indo-Malesia and southern New Guinea. However, it is morphologically distinct, and the major distinguishing character of entire margins for calyx and bracts is unique in the genus. This species, described here as A. integra, occurs only in the Northern Territory of Australia. It therefore has the dual distinction for an Australian mangrove species of not only being endemic, but also being absent from the floristically rich tidal forests of north-eastern Queensland. Notes on its floral phenology, distribution and ecology are also given.* Aust. Inst. Marine Sci. Contrib. No. 417.

The putative hybrid tree taxon, Sonneratia alba x S. lanceolata, previously reported for two incomplete herbarium specimens from northern Australia and south-east West Irian, has since been observed and collected in mangrove forests of southern Papua New Guinea. It is morphologically uniform and is described as S. xurama. Notes on its floral phenology, distribution and ecology are given, including a key to all major Sonneratia taxa in this region.

Semantic Value

WHILST the tonal languages spoken in West Africa have latterly received W a good deal of attention, it has not been generally realized that such languages are found also in parts of New Guinea. In New Guinea there are in fact two types of tonal languages. In one, the tones may be described as ” ornamental”, i.e. though they exist they do not seem to have semantic value, but rather to be connected with a certain type of sentence rhythm; in the other the tone systems are more definitely akin to those of Western Africa, and in such languages tones do possess semantic value. It is interesting that one at least of the latter group of languages tends also to be monosyllabic. It is hoped to provide a study of the former class of languages—at least one representative of which is also found in Northern Australia—at a later date. The present paper is occupied with the languages in which tones do have semantic value.These languages, so far as has been observed yet, are two in number, and they are spoken along the shores of Huon Gulf, in north-eastern New Guinea. The map on p. 186 will show their locations. Both belong to the group of languages known as Melanesian, and this makes the occurrence of tones even less expected. A considerable number of other languages are spoken round about this area, and though some of these also are Melanesian, they do not seem to have developed tones. Moreover, it would seem that the use of tones in these two languages antedates the coming of the Melanesian languages, for reasons that will be given towards the end of this paper.

Phylogenetic analysis of melanotaeniid mtDNA cytochrome b and tRNA Pro-control region sequence is broadly consistent with the current taxonomy. However, the molecular phylogeny supports the elevation of M. s. australis to full species status and indicates either that it is a composite species or has introgressed with sympatric Melanotaenia species. Phenotypically cryptic mtDNA diversity in north-eastern Australia possibly represents an undescribed species. Six major monophyletic clades present in the phylogeny were strongly supported by morphological data. The clades represent three biogeographic regions. Fish from northern New Guinea form a monophyletic clade, within which Melanotaenia and Glossolepis are polyphyletic. The divergence of this clade from those in southern New Guinea is consistent with the final uplift of the Central Highlands 5 million years BP. North-western New Guinea and associated islands represent another highly divergent, monophyletic clade of a similar age to that in northern New Guinea. The remaining four clades form a monophyletic assemblage restricted to southern New Guinea and Australia: one in northern Australia, one with a disjunct distribution in north-western and eastern Australia, one widespread throughout Australia and southern New Guinea, and one in southern New Guinea with an outlying species in northern Australia. The phylogenetic relationships between Australia and southern New Guinea are consistent with episodic connection via the freshwater Lake Carpentaria during periods of low sea level.

THE bare-rumped sheathtailed bat Saccolaimus saccolaimus is a poorly understood species that has a wide distribution covering parts of India, Sri Lanka, Thailand, Myanmar, Malaya, Indonesia, New Guinea, the Solomon Islands and Northern Australia (Bonaccorso 1998). First collected in Australia by De Vis near Cardwell, the current known distribution in Queensland (Qld) extends from Bowen to Cooktown with one isolated specimen collected near Coen on Cape York Peninsula (Hall 1995; Duncan et al. 1999). It has also been recorded in the Alligator River area in the Northern Territory (McKean et al. 1981). The conservation status of S. saccolaimus in Qld has recently been defined as ?Critically Endangered?, and the species has not been recorded anywhere in Australia for at least 18 years (Duncan et al. 1999; Menkhorst and Knight 2001). The likely reasons for the apparent decline are unclear, but may involve land-clearing and changed fire regimes in the coastal zone where it is thought to occur (Duncan et al. 1999). In contrast, Bonaccorso (1998) considers S. saccolaimus to be secure, albeit also poorly known in Papua New Guinea.

Distribution And Ecology

Water striders or pond skaters belonging to the subfamily Gerrinae are common inhabitants of various types of fresh water throughout eastern and northern Australia. The present paper deals with the 13 species (in 5 genera) known from Australia. Redescriptions or descriptive notes, illustrations, and keys to adults and nymphs of all species are provided and their distributions recorded and mapped.Tenagogerris pallidusand T. femoratus (both from Northern Territory and Western Australia), Tenagogonus australiensis (Queensland), Limnometra ciliodes (Queensland, Papua New Guinea and Irian Jaya), and Limnogonus fossarum gilguy (Northern Territory, Queensland, South Australia, Western Australia, Indo-Malayan Archipelago, and West Pacific to Samoa and Tonga) are described as new. Limnometra poliakanthinaNieser & Chen is synonymised with L. cursitans (Fabricius) and Hydrometra australis Skuse (= Limnometra skusei Torre-Bueno) with Limnogonus luctuosus (Montrouzier). The evolution and zoogeography of Australian water striders are discussed. Finally, we discuss the ecology of the gerrine water striders of Australia in relation to our present knowledge about habitats, phenology, wing polymorphism, and association between species.

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.

This volume provides the first detailed account of the Chroococcales of north-eastern Australia. It provides keys, morphological and ecological data for 6 families, 33 genera and 112 species, and photomicrographs and original illustrations to enable the identification of natural populations based on stable and recognizable characters observable with the aid of light microscopy. Distributional data are based on extensive surveys at 270 sites representing the major freshwater habitats including rivers and streams, palustrine and lacustrine wetlands, thermal springs, and man-made reservoirs in Queensland and the Northern Territory as well as a review of the Australian phycological literature.
