Only 31 specimens of Sminthopsis archeri have been studied. These have come from Papua New Guinea and Cape York, Australia. Females are seasonally polyoestrous. Oestrous cycles in captive females are characterized by an increase body weight until just before ovulation. Changes in pouch condition are described. Eight nipples are usual.

While certain ecological groups of trombiculid mites are thought to be specialised for nest occupation, supporting evidence is rare. A putatively nest-specialised trombiculid is here described in detail. Larvae, a deutonymph and adults of the trombiculid genus Ascoschoengastia were collected from three tree hollow nests occupied by Eclectus parrots (Eclectus roratus) and Sulphur-crested Cockatoos (Cacatua galerita) at Iron Range, Cape York Peninsula. The larvae are A. (Laurentella) lorius (Gunther), a species originally described from an Eclectus parrot in Papua New Guinea. Deutonymph and adult Ascoschoengastia are also assigned to this species based on their co-occurrence with larvae in this specific and isolated microhabitat. A. (L.) lorius is inferred to have a nest-based life history. Active stases are described with attention to sensory setae. The previous synonomy of A. (L.) daria with A. (L.) lorius is rejected. A key to Australian species of Ascoschoengastia is presented.

A survey of Australian Phyllophorinae is presented. The entire fauna is represented by two species in two genera. Siliquofera grandis Blanchard, a species widely distributed in Papua New Guinea, is recorded from Iron Range, Queensland. Phyllophorella queenslandica Rentz, Su, Ueshima sp. nov. is described from Kuranda, Queensland and recorded from several localities on the Cape York peninsula. The unusual habits of the subfamily are discussed and the equally unusual karyotype of Phyllophorella queenslandica Rentz, Su, Ueshima sp. nov. is presented.

Ketamine Hcl

We evaluated two methods (daytime and night-time searches) for capturing montane possums, the dose of ketamine HCl needed for their short-term restraint, its influence in effect length and recovery length, the effect of body weight, and differences between species and sexes. Daytime searches required significantly more effort to find animals, and provided significantly fewer captured animals per unit effort, than night-time searches. Chances of capturing animals once detected were higher during daytime. Drug doses of 9–17 mg kg–1 immobilised animals within 1 min (±1.25, s.d.), effects lasted 19 min (±1.34), and recovery took an additional 28 min (±1.29). Significant effects on effect length and recovery were observed only for drug dose, but these are weak. We recommend finding animals before dawn, following them to their dens, and capturing them during daylight as the safest and most effective method for montane possums of New Guinea. For short-term restraint, a dose of 10 mg kg–1 ketamine HCl is sufficient.

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.

Three New Species

Until now, Penicillidmus was represented by two Australian and one Papuan species, distributed in Cape York, northern Queensland, and Lavongai Island, Papua New Guinea. Three new species are described, all known to occur in Luzon, the Philippines: Penicillidmus maquilingensis sp. n., P. lagunensis sp. n. and P. luzonicus sp. n. The discovery of Penicillidmus in the Oriental region suggests a broader distribution of this genus in Southeast Asia.

The volatile leaf oils of glasshouse-grown plants representing natural populations of E. urophylla S.T.Blake, E. pellita F.Muell. and E. scias L.Johnson from the Lesser Sunda Islands, Australia, Papua New Guinea and Irian Jaya were examined for patterns of variation and relationships. The steam distilled oils of the three species were found to be largely monoterpenoid in character and similar qualitatively but variable quantitatively. The relative proportions of α-terpinyl acetate, 1,8-cineole, β-pinene, caryophyllene, α-phellandrene and p-cymene provided good discrimination between species and provenances. The mix of compounds and relatively low yields were such that the oils have no commercial potential. Principal component analysis of oil compositional data revealed groupings of populations consistent with contemporary thinking on the systematics of this complex. The four populations of E. urophylla from Wetar Island included in this study emerged as a group distinct from the main cluster of populations of that species. There was some support in the data for the distinction of high-elevation populations of E. urophylla from eastern Timor from other populations of the species and for the separation of E. scias from E. pellita, although the data, based on limited sampling, was inconclusive. Patterns in the oils of Cape York, Papua New Guinea and Irian Jaya provenances of E.pellita were variable. Evidence from other characters (e.g. adult morphology) will be needed to support the hypothesis that the Cape York and New Guinea populations of E. pellita constitute a new taxon.

As a photojournalist, writer and producer of television documentaries, Ben Bohane has spent the past 12 years posting stories about life on the islands of Melanesia to the Western media—illuminating the struggles and the spirit worlds behind the news. Melanesia is as close to Australia as a 150km cruise from the tip of Cape York across the Torres Strait to Papua New Guinea, connecting Australasia to the rest of Oceania and Asia. Until recently, though, these islands have seemed distantly removed from Australia and New Zealand’s notion of its international community.

The Common

THE common spotted cuscus Spilocuscus maculatus is a relatively large nocturnal arboreal possum with a preference for tropical lowland forests. Its distribution is centred on New Guinea, but extends to some adjacent landmasses, including a number of satellite islands and Cape York Peninsula in Australia (Flannery 1994; Winter and Leung 1995; Heinsohn 2000). It appears to be principally folivorous and partially frugivorous and forages in the canopy, subcanopy, and understorey of tropical forests, though it may venture to the ground to cross gaps. After a night of foraging, S. maculatus typically rests by day hidden amidst the thick foliage of the canopy, in liana tangles or thickets, and appears to be less dependent on, or less inclined to use tree hollows than some other possum species (Heinsohn 1998b, pers. obs.).

Basal Concentration

Female kowaris are seasonal breeders (May-November) with a gestation of 32.5 +/- 1.8 days (mean +/- s.d., n = 35). The oestrus cycle including pregnancy is 59.0 +/- 6.7 days in duration (mean +/- s.d., n = 12) and is not significantly different from the non-pregnant cycle of 60.3 +/- 7.1 days (mean +/- s.d., n = 15) (P greater than 0.1). Animals maintained on a fixed diet show an increase and fall in body weight before oestrus and again at the end of the oestrous cycle or a pregnancy; these changes correlate closely with progesterone concentration. Plasma progesterone concentration and body weight were measured in six kowaris undergoing an oestrous cycle then a pregnancy in the breeding season of 1981. The basal concentration (mean +/- s.d.) of progesterone prior to the breeding season was 0.35 +/- 0.21 ng mL-1. There were mean rises of 1.84 +/- 1.1 and 2.47 +/- 1.5 ng mL-1, respectively, before the first and second oestrous periods which had declined to near basal levels by the day of oestrus. Peak values of 9.9-11.5 ng mL-1 were measured between days 23 and 30 of oestrous cycle and pregnancy. The pattern of changes in body weight and plasma progesterone concentration was similar in pregnant and non-pregnant animals but the decline in weight and progesterone occurred earlier in pregnant kowaris.
