In Australia the genus Euphorbia L., sensu stricto, is represented by seven indigenous species in three subgenera. One species has been reported from Papua New Guinea and parts of South-east Asia, another from the New Hebrides; the remaining species are endemic to Australia. Two taxa are described as new species, viz. Euphorbia parvicaruncula and Euphorbia planiticola, and two former species are reduced to infraspecific rank, viz. Euphorbia tannensis subsp. eremophila, and Euphorbia tannensis subsp. eremophila var. finlaysonii. Observations are made on geographical distributions, interspecific relationships, and chromosome numbers.

The scorpion-tailed orb-weaving spiders in the genus Arachnura Vinson, 1863 (Araneidae Clerck, 1757) are revised for Australia and New Zealand. Arachnura higginsii (L. Koch, 1872) only occurs in Australia and A. feredayi (L. Koch, 1872) only in New Zealand. A single female collected in south-eastern Queensland (Australia) is here tentatively identified as A. melanura Simon, 1867, but it is doubtful that this species has established in Australia. Two juveniles from northern Queensland do not conform to the diagnoses of any of the above species and are illustrated pending a more thorough revision of the genus in South-East Asia and the Pacific region. An unidentified female from Westport (New Zealand) does not conform to the diagnoses of A. feredayi and A. higginsii, but is not described due to its poor preservation status. Arachnura caudatella Roewer, 1942 (replacement name for Epeira caudata Bradley, 1876), originally described from Hall Sound (Papua New Guinea) and repeatedly catalogued for Australia, is considered a nomen dubium.

The Australian pyralid stem borers of Gramineae, Cyperaceae, and Juncaceae, previously assigned to Schoenobius Duponchel and Scirpophaga Treitschke, are here referred to six genera. Scirpophaga Treit. - Eight species are recognized: S. chrysorrhoa Zeller, S. phaedima, sp. nov., S. limnochares, sp. nov., S. xantharrenes, sp. nov., S. imparella (Meyrick), S. helodes, sp. nov., S. percna, sp. nov., and S. ochroleuca (Meyrick). Though some of these bear a superficial resemblance to the true rice stem borers, the genus includes species whose larvae attack sedges (Cyperaceae). Helonastes, gen. nov. - The genus is based on a new species, H. acentrus, associated with Eleocharis (Cyperaceae) in central Queensland. Niphadoses, gen. nov.-The genus is erected to include three new Australian species, N. palleucus, which is associated with cultivated rice in north-western Australia, N. elachia, and N. hoplites, together with N. chionotus (Meyrick) from New Guinea and N. gilbiverbis (Zeller) from India. Catagela Walker. - A new species, C. adoceta, from northern Australia, is described. Tryporyza gen. nov. - The genus is established to receive the two important stem-borer pests of cultivated rice, Tipanaea innotata Walker from south-east Asia and northern Australia and Chilo incertulas Walker from south-east Asia, previously referred to Scirpophaga and Schoenobius respectively. Also included are Scirpophaga butyrota Meyrick from New Guinea and Schoenobius melanostigmus Turner from the Cape York Peninsula. It is suggested that T. innotata already occurred in northern Australia before European settlement. Tipanaea Walker. - The genus is restricted to the single Australian species, T. patulella Walker, associated with Juncaceae. Genitalic and other structures used to distinguish these genera are discussed. The genitalia of both sexes and the wings of the Australian species are figured, and keys to the genera and species are included.

AbstractThis study is an unprecedent exploration of the diversity of 226 diploid bananas genotyped with restriction-site-associated DNA sequencing data (RADseq) to clarify the processes that led to the creation of edible diploid AA bananas. This wide set included 72 seedy bananas, mostly M. acuminata from different genepools, and 154 edible, i.e. parthenocarpic and sterile, AA accessions obtained from genebanks and recent collecting missions. We highlighted the geographic organisation of the diversity of edible AAs and confirmed the admixed nature of many and further conducted introgressions tests within AAs from South East Asia and New Guinea. Lastly, taking advantage of the presence of an important number of M. acuminata ssp. banksii (22) and of AA from Papua New Guinea (76) in the set, we investigated the patterns of differentiation between wild and cultivated bananas seemingly belonging to the same genepool. We discovered a few cultivated AAs that may be of pure origins both in South-East Asia and in New Guinea. We also detected two undefined parental genepools in South East Asia for which regions of origin could be Thailand and a region between north Borneo and the Philippines, respectively. Finally, we suggest the existence of a third genepool in New Guinea island that might be a source population for both edible AAs and the local M. acuminata ssp. banksii.

Three new species of Ventilago from Malesia are described and illustrated here: V. crenata from New Guinea, V. ferruginea from Borneo, Singapore and Sumatra and V. flavovirens from Borneo. The morphology of V. dichotoma, V. ferruginea and V. flavovirens is compared, and a key to the Ventilago species of Borneo is presented. An IUCN conservation status assessment is given for each new species.

Bactrocera Macquart (Diptera: Tephritidae) is a genus of nearly 500 species, the majority of which are endemic to tropical South-East Asia and Australasia (Drew 1989). Nearly all Bactrocera have frugivorous larvae that feed on the fleshy fruit of tropical trees, shrubs, and vines, and some species are major horticultural pests (White & Elson-Harris 1992). In this paper,where the term ‘fruit fly’ is used, we are referring explicitly to species of Bactrocera.

Abstract. Two new genera and eight new species of benthic foraminifera are described from the shallow water, tropical lagoon of Madang, Papua New Guinea. The new hauerinid genus Pseudolachlanella is characterized by juvenile cryptoquinqueloculine, adult almost massiline arranged chambers, and a slitlike, curved aperture with parallel sides and a long, slender, curved miliolid tooth. Pitella haigi n. gen., n. sp. is a new foraminifera with cryptoquinqueloculine arranged chambers, an almost entirely pitted shell surface (pseudopores) and a rounded aperture with a short simple tooth. Among the other species described as new are four hauerinids and two agglutinated foraminifera All new species described here occur sporadically in the shallow water back- and forereef environments of the lagoon (0–55m), and live infaunally and epifaunally in well-oxygenated, fine and coarse grained biogenic sediments. They are absent in muddy, organic-rich, low-oxygen sedimentary environments within bay inlets where variations of salinity are considerable.
