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 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.

Tree Frogs

We examined differences in morphology and advertisement calls of a large sample of frogs from the Australo-Papuan Region that resemble Litoria bicolor, and compared them with examples of that species from Australia. Consistent differences in body size, body proportions, and advertisement call structure among populations demonstrate that at least seven distinct species occur in the Australo-Papuan region, and that only the population represented by the holotype from the Northern Territory of Australia is Litoria bicolor s.s. Herein we describe four new species from the Papuan Region and comment on the origin and evolution of the Papuan members of the Litoria bicolor complex in the region.

The Tropics

Two new agraeciine genera and five new species are described from northern Australia. Both genera have species that live in mixed woodlands in the tropics. Armadillagraecia Rentz, Su, Ueshima, Robinson gen. nov. is known from two species in the Northern Territory and one from Queensland. Kapalgagraecia Rentz, Su, Ueshima, Robinson gen. nov. is known from two species, one apparently widespread in the Northern Territory, the other from Groote Eylandt, NT. Cytological data are provided for all Armadillagraecia species but not for Kapalgagraecia. A table is presented documenting knowledge of the known cytology of all Agraeciini. The calling songs of both A. mataranka and A. yerilla Rentz, Su, Ueshima, Robinson gen. et spp. nov. are noted and documented by sonograms. Known biological, ecological and distributional data are presented.

Foam Nest

The new leptodactylid genus Megistolotis and new species Megistolotis lignarius are described from localities in northern Western Australia and the Northern Territory. M. lignarius inhabits scree slopes and escarpments. The male mating call is a single note resembling the striking of timber. The spawn clump is a foam nest anchored to stones at the edge of small, temporary pools, and the tadpoles have intense black bodies and fins, and suctorial mouths. Megistolotis is most closely related to the limnodynastine genera Limnodynastes and Heleioporus.

This is an account of portion of the botanical collections of the Northern Australia Regional Survey, 1946–47, chiefly from the Darwin–Katherine area. Families fully considered are Anacardiaceae, Aquifoliaceae, Araceae, Barringtoniaceae, Burseraceae, Casuarinaceae, Cochlospermaceae, Lauraceae, Leguminosae-Caesalpinioideae, Leguminosae-Mimosoideae (except Acacia), Meliaceae, Myristicaceae, Nymphaeaceae, Palmae, Pandanaceae, Passifloraceae, Pittosporaceae, Rhamnaceae, Rhizophoraceae, Rutaceae, Sapindaceae, Sonneratiaceae, and Sphenocleaceae. A few species of the following families are also discussed: Combretaceae, Cyperaceae, Euphorbiaceae, Gramineae, Leguminosae-Papilionatae, and Moraceae. In addition to discussions on taxonomy, synonymy, and orthography of names, the following additions to the flora of the Northern Territory are recorded: new species: Dendrolobiunz stipatum, Desmodizim polyneurum, Horsfieldia australiana, Sclerandrittm grandiflorum, and Vavaea australiana; species not previously recorded from Australia: Mimosa acanthocarpa, Pistia stratiotes, and Sphenoclea xeylanica; species already known from other parts of Australia: Albixia canescens, Casuarina cunninghamiana, Colubrina asiatica, Cryptocarya cunninghamii, Cyperus platystylis, Cyperus ramosii, Hymenachne amplexicaulis, Neptunia gracilis, Passiflora foetida, and Petalostigma banksii. Two new names are proposed, Eulalia mackinlayi (F. Muell.) S. T. Blake and Terminalia ferdinandiana Exell. The genera Horsfieldia, Pistia, Sphenoclea, and Vavaea have not previously been recorded from Australia and Albixia, Colubrina, Cryptocarya, Dendrolobium, Hymenachne, and Mimosa have not previously been recorded from the Northern Territory. Sphenoclea represents a new family (Sphenocleaceae) for Australia. Cochlospermum fraseri, Cryptocarya cunninghamii, and Sphenoclea xeylanica are also recorded for the first time from Queensland. The following reductions to synonymy are made: Alectryon bleeseri O. Schwartz to Cupaniopsis alliacardioides (A. Rich.) Radlk.; Barringtonia denticulata (Miers) Knuth to B. gracilis (Miers) Knuth, which is treated as distinct from B. aczttangula (L.) Gaertn.; Buchanania oblongifolia W. V. Fitzg. and B. muelleri Engl. var. pilosa Engl. to B. obovata Engl.; Buchanania muelleri Engl. to B. arborescens (BI.) Bl.; Ilex peduncularis F. Muell. to I . arnhemensis (F. Muell.) Loes.; and Pandanus delestangii Martelli to P. aquaticus F. Muell.

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.

Three New Species

Three new species of the rodent louse genus Hoplopleura (Anoplura: Hoplopleuridae) are described and illustrated from Australia: H. melomydis new species from Melomys burtoni (Muridae: Hydromyini, grassland melomys) and M. capensis (Muridae: Hydromyini, Cape York melomys) from Queensland; H. notomydis new species and H. setosa new species from Notomys alexis (Muridae: Hydromyini, spinifex hopping mouse) from the Northern Territory. These new louse species are the first lice recorded from each of the three host rodent species.
