The genus Marsdenia R.Br. is circumscribed utilising data from taxonomic history and morphology. and its relationship to other genera in the Marsdenieae is discussed. Genera that have usually been or commonly regarded as distinct. i.e. Gymnenla R.Br., Leichardtia R.Br., Bidaria (Endl.) Decne. and Thozetia F . Muell . ex Benth., are discussed and considered congeneric with Marsdenia. A revision of the Australian and Papuasian (Irian Jaya, Papua New Guinea, Solomon Islands) taxa of Marsdenia is presented and 78 species (one with two subspecies) and one putative interspecific hybrid are recognised. Forty-six taxa are accepted as new, namely Marsdenia ambuntiensis, M. archboldiana, M. argillicola, M . arfakensis, M. Belensis, bilobata, bliriensis, M. Brassii, M. Brevis, M.

Circumscription of the genus Ichnocarpus R. Br. is discussed and Micrechites Miq. and Lamechites Markgraf are placed in synonymy. Ichnocarpus R. Br. is revised for Australia and Papuasia (Irian Jaya, Papua New Guinea and the Solomon Islands). Three species are recognised in this region, namely I. archboldianus comb. nov. (Micrechites archboldiana Merr. & Perr.), I. frutescens (L.) W. T. Aiton and I. serpyllifolius comb. nov. (Ficus serpyllifolia Blume). Lumechites schlechteri Markgraf, Micrechites rhombifolia Markgraf, M. rhombifolia var. lanceolata Markgraf and Ichnocarpus salornonensis C. T. White are newly placed in the synonymy of Ichnocarpus serpyllifolius. The new combination I. polyanthus (Micrechites polyantha Miq.) is made for a Malesian species west of Papuasia. The names Ichnocarpus leptodictyus F. Muell. and Micrechites rhombifolia Markgraf are lectotypified. Generic and specific descriptions, a species key, notes on variation, distribution, habitat and conservation status are provided.

AbstractThe small waterstriders of the subfamily Trepobatinae have radiated extensively on New Guinea and in surrounding archipelagos. All of the marine forms of the subfamily are found in this region, with the exception of one monotypic genus occurring on brackish water in the eastern tropical Pacific. The present study, the fourth in a series of reports dealing with Melanesian Trepobatinae, covers these regional marine taxa. The tribe Stenobatini, proposed in Part 1 of this series to hold the genera Stenobates Esaki, type-genus, plus Rheumatometroides Hungerford and Matsuda, and Stenobatopsis gen. n. (as undescribed genus 2), is revised, two new genera are proposed, and keys to genera and species are provided, followed by synonymies, diagnoses and discussion of the constituent genera. The following new taxa are proposed within the Stenobatini: Pseudohalobates gen. n., monobasic, type-species S. inobonto sp. n. from Indonesia (Celebes, Moluccas, Talaud Archipelago, Biak and Yapen islands, and Vogelkop Peninsula of Irian Jaya), and the Philippines (southern Mindanao); Stenobatopsis gen. n., monobasic, type-species S. stygius sp. n. from Halmahera; Thetibates gen. n., type-species Rheumatometroides serena Lansbury, from northern Papua New Guinea and the Solomon Islands; Rheumatometroides kikori sp. n. from the Kikori delta of southern Papua New Guinea; R. insularis papar n. ssp. from Sabah, north Borneo; R. sele sp. n. from the Vogelkop Peninsula of Irian Jaya; R. wabon sp. n. from Biak Island; Stenobates fakfak sp. n. from the Vogelkop Peninsula of Irian Jaya; S. kamojo sp. n. from Biak Island, Salawati Island, Yapen Island, and the Vogelkop Peninsula of Irian Jaya; S. kasim sp. n. from Salawati Island; S. labuha sp. n. from Bacan and Halmahera; S. langoban sp. n. from Palawan; S. sangihe sp. n. from the Sangihe Archipelago; and S. zamboanga sp. n. from Mindanao. Other nomenclatural changes: Rheumatometroides carpentaria (Polhemus & Polhemus), comb. n.; Rheumatometroides insularis insularis (J. Polhemus & Cheng), comb. n.; Stenobates makraitos (Chen & Nieser) comb. n.; Thetibates matawa (Lansbury), comb. n. [ = Rheumatometroides aqaaqa (Lansbury), syn. n.]; Thetibates serena (Lansbury), comb. n. Habitat and distributional data are given for these taxa, accompanied by keys, figures of key characters and distribution maps.

Three species are recognised among material previously referred to as Thylogale brunii. Thylogale brunii as newly defined here is distributed at low elevations in sourhern New Guinea, and inhabits areas with a marked dry season and a savannah-forest ecotone. Thylogate browni includes two subspecies: T. b. lanatus from subalpine grasslands above 3000 m on the Huon Peninsula, and T. b. browni from the Bismarck Archipelago and central-eastern New Guinea, where it occurs from the Cyclops Mountains in the West to the Bulolo area in the east at altitudes up to 2000 m. lt prefers disturbed habitats. Thylogale calobyi n. sp. is restricted to subalpine grasslands along the Central Cordillera at above 3000 m in Papua New Guinea. All three species seem to be sensitive to hunting pressure, with local extinctions being recorded for T. brunii and T. browni in historic times, and a prehistoric extinction for a population of uncertain status from subalpine grasslands in Irian Jaya.

A taxonomic revision of Didymochlaena (Didymochlaenaceae) from Asia and the Pacific region is conducted based on morphological and molecular evidence. Seven species are recognized, of which four are described as new and a new status is raised to a species from a variety. These four new species include D. fijiensis from Fiji, D. philippensis from the Philippines, D. punctata from Indonesia, Malaysia, and Thailand, and D. solomonensis from the Solomon Islands. The new status is D. oceanica from Papua New Guinea. Six of the seven species have all been erroneously treated as D. truncatula by earlier pteridologists. A key to the species is provided and descriptions of all species are given.

Ross River virus (RRV) is the most medically significant mosquito-borne virus of Australia, in terms of human morbidity. RRV cases, characterised by febrile illness and potentially persistent arthralgia, have been reported from all Australian states and territories. RRV was the cause of a large-scale epidemic of multiple Pacific Island countries and territories (PICTs) from 1979 to 1980, involving at least 50,000 cases. Historical evidence of RRV seropositivity beyond Australia, in populations of Papua New Guinea (PNG), Indonesia and the Solomon Islands, has been documented. We describe the genomic characterisation and timescale analysis of the first isolate of RRV to be sampled from PNG to date. Our analysis indicates that RRV has evolved locally within PNG, independent of Australian lineages, over an approximate 40 year period. The mean time to most recent common ancestor (tMRCA) of the unique PNG clade coincides with the initiation of the PICTs epidemic in mid-1979. This may indicate that an ancestral variant of the PNG clade was seeded into the region during the epidemic, a period of high RRV transmission. Further epidemiological and molecular-based surveillance is required in PNG to better understand the molecular epidemiology of RRV in the general Australasian region.
