A new species of bethylid wasp (Hymenoptera) from New Zealand,with comments on its life history and host

A new species of parasitoid wasp Chilepyris platythelys (Chrysidoidea: Bethylidae), from New Zealand, is described and illustrated. Its life history is described and its host, an anobiid (Coleoptera) larva, Hadrobregmus (Megabregmus) magnus is mentioned as the first host record for the genus Chilepyris.     

A phylogenetic reappraisal of the birdwing genus Ornithoptera (Lepidoptera: Papilionidae: Troidini) and a new theory of its evolution in relation to Gondwanan vicariance biogeography

The troidine papilionid genus Ornithoptera is shown to be distinct from Troides In order to reappraise the interrelationships of the member species of Ornithoptera, and to test the resultant theory of their evolution against biogeographical data, the genus is revised using Hennigian cladistic methodology through computer analysis. The input data for this was drawn equally from immature stages and adult characters. A single cladogram hypothesising the likely phylogeny of the Ornithoptera species was generated. With minor weighting of a single important adult character, a further two cladograms were generated, one of which is similar to hypotheses proposed by previous workers. Based on these findings, and on ecological data, notably larval foodplant relations with Aristolochiaceae, as well as present-day biogeographical data, a new theory of the origin and evolution of Ornithoptera is presented which fits well Gondwanan vicariance events ascertained by geological studies: essentially that Ornithoptera evolved on northward drifting Australia, allopatrically from Troides on the Indian plate, and therefore that Ornithoptera did not reach the Australian Subregion via Troides-like ancestors in Southeast Asia as has been previously postulated. As ‘living fossils’ representative of an ancient, Gondwanaland-derived, austral faunal element, the Ornithoptera should be regarded even more highly in terms of their ‘conservation value’.     

Mangrove halacarid fauna (Halacaridae,Acari) of the Dampier region,Western Australia,with description of five new species

Amongst the vagile epifauna on the mangrove trees Avicennia marina and Rhizophora stylosa, Acari numerically play an important role, contributing 20-75% of the fauna. The two major groups are the prostigmatids and oribatids. Amongst the prostigmatid mites, halacarids are regularly present from the upper littoral fringe, inundated only at very high tide, to the permanently wet substrata adjacent to tide pools. Oribatids are most abundant in permanently wet substrata and often dominate the mite fauna. Five halacarid species, regularly found amongst the epibios on mangroves, are described, Isobactrus australiensis n. sp., Rhombognathus ocularis n. sp., Agauopsis dasyderma n. sp., Copidognathus lutarius n. sp. and C. piger n. sp. Isobactrus australiensis often is the only mite in the upper zone not reached by every high water.

Casinaria,a paraphyletic ichneumonid genus (Hymenoptera), and a revision of the Australian species

The Australian species of the campoplegine ichneumonid genus Casinaria are revised and an illustrated key is provided for their identification. Eleven species are recognized, but one is not formally named. The Australian species are referable to two morphologically and biologically distinct groups, the meridionalis species-group (containing amarilla sp. nov., hesperiophaga sp. nov. and meridionalis (Turner)) which are parasitoids of hesperiid larvae, and the siccata species-group (containing eremica sp. nov., micra sp. nov., mythologica sp. nov., pavlova sp. nov., siccata sp. nov., virgata sp. nov., woowonga sp. nov. and species A) which parasitize the larvae of a variety of smaller moths. The holophyly of each of the two species-groups is demonstrated, but characters supporting the holophyly of the genus could not be found, suggesting that Casinaria, as currently recognized, may either be paraphyletic or polyphyletic.     

The taxonomy and biology of the Polystomatidae (Monogenea) in Australian freshwater turtles (Chelidae,Pleurodira)

Polystomoides scottae n. sp. is described from the urinary and accessory bladders of Chelodina expansa. Four species of Neopolystoma are described from the conjunctival sacs of Australian freshwater turtles (Chelidae): Neopolystoma cribbi n. sp. from Emydura signata, E. macquarii, Elseya latisternum and Chelodina expansa; Neopolystoma spratti n. sp. from Chelodina longicollis; Neopolystoma tinsleyi n. sp. from Chelodina expansa; and Neopolystoma queenslandensis n. sp. from Emydura signata and E. macquarii. Polystomoides australiensis, Neopolystoma macleayi and N. chelodinae are redescribed from new individuals. Neopolystoma australis is made a junior synonym of N. kreffti. P. australiensis, N. macleayi and N. cribbi produced on average 5·6, 4·3 and 0·7 eggs per day, respectively. Eggs of P. australiensis take 33–57 days at 18–24°C and 30–33 days at 24–28°C to develop and hatch. Oncomiracidia of P. australiensis and N. macleayi had 64 ciliated cells; the patterns of the ciliated cells are the same for both species. Different sizes of worms in different sites in the hosts suggest strongly that the oncomiracidia of P. australiensis and N. macleayi enter the host, migrate to the ureters, possibly to the kidneys, then to the urinary bladder and finally to either the accessory bladders or cloaca. Successful cross-infection experiments between host genera (Emydura to Elseya) indicated that P. australiensis and N. macleayi have a low degree of host specificity.     

A primitive representative of the Parabathynellidae (Bathynellacea,Syncarida) from the Yilgarn Craton of Western Australia

Billibathynella humphreysi gen. et sp. nov. is described from calcrete aquifers located in the Yilgarn Craton of north‐western Australia. This is the first parabathynellid known from the Australian Precambrian shields, which have never been inundated by the sea. A comparison of the primitive species so far known from Australia and other continents points to the new species as being the most primitive among the parabathynellids. It further suggests that the new genus has an affinity to Notobathynella Schminke, but differs in having a six‐segmented antenna and a large epipod of the male thoracopod VIII. An attempt to relate the primitiveness of the new species to the historiogeological characteristics of the region has led to the conclusion that the recent parabathynellids could have emerged from freshwater epigean ancestors. It is further assumed that the transition of their ancestors to groundwaters happened in Notogaea.     

1945-1973年澳大利亚高等教育发展的原因--兼评存在的问题

1945-1973年期间澳大利亚高等教育获得快速发展,其原因主要有几个方面:一是社会经济发展的需要;二是世界科技革命的冲击;三是全社会对高等教育价值的认识和肯定;四是澳大利亚各级政府的大力支持.但同时也存在一些问题,诸如政府对高等教育发展缺乏长期的整体规划,教育机会不均等.

The species of Encarsia Förster known from Australia are revised. This study is based mainly on material collected over the last 10 years. Ninety‐four species are recognized, including 38 new species, and seven new records for Australia. All species are fully described or diagnosed, and illustrated by microphotographs. Seven new specific synonymies are proposed and two lectotypes are designated. A key to the females of Australian species of Encarsia is provided. The known hosts and distribution are summarized. The diversity of the Australian Encarsia fauna is discussed.
