The breeding systems of Stylidiurn grarninifolium and S. producturn (= S. grarninifoliurn var. caulescens) were studied by observing the phenology of individual flowers and inflorescences, and relating the data to a series of pollination experiments within and between the species. Inter-specific pollinations yielded similar levels of seed-set to crosses within the species indicating a close relationship between the taxa. Self-pollination of either species is uncommon; however, when it occurs, the majority of selfed ovules are aborted post-zygotically, probably by a system of recessive lethals, as there is no indication of an incompatibility system. It is concluded that the breeding systems of S. grarninifoliurn and S. productum, two of the few eastern Australian species, are similar to those of many Stylidiurn species from the south-west, casting doubt upon hypotheses that the breeding system has led to high rates of speciation in the south-west.

Host Relations

The geographical distribution and host relations of the 12 species of Charletonia whose larvae are known to parasitise 'short-horned' grasshoppers (Orthoptera) in Australia are described. The eight species for which there are adequate records occupy territories in the form of mainly overlapping bands running approximately from north-west to south-east and succeeding each other in a south-west to north-east direction across the continent, in correlation with isopleths of mean monthly effective moisture for the summer months. As many as 107 species of grasshoppers are attacked, encompassing all four of the Australian subfamilies of Acrididae, the Morabinae (Eumastacidae), and occasionally the Pyrgomorphidae. There is little evidence of host specificity and none of sexual preference. Sites of attachment on the host vary with the species of mite, from predominantly the prosternum to predominantly the alar organs, or, less frequently, various. Most of the host individuals were attacked by only one mite.

Finding Australian Birds is a guide to the special birds found across Australia's vastly varied landscapes. From the eastern rainforests to central deserts, Australia is home to some 900 species of birds. This book covers over 400 Australian bird watching sites conveniently grouped into the best birding areas, from one end of the country to the other. This includes areas such as Kakadu in the Top End and rocky gorges in the central deserts of the Northern Territory, the Great Barrier Reef in Queensland, rainforests distributed along the eastern Australian seaboard, some of the world's tallest forests in Tasmania, the Flinders Ranges and deserts along the iconic Strzelecki and Birdsville Tracks in South Australia, and the mallee temperate woodlands and spectacular coastlines in both Victoria and south west Western Australia. Each chapter begins with a brief description of the location, followed by a section on where to find the birds, which describes specific birdwatching sites within the location's boundaries, and information on accommodation and facilities. The book also provides a comprehensive 'Bird Finding Guide', listing all of Australia's birds with details on their abundance and where exactly to see them. Of value to both Australian birdwatchers and international visitors, this book will assist novices, birders of intermediate skill and keen 'twitchers' to find any Australian species.

The precise type-locality of the infrequently encountered Western Australian species Nascio chydaea Olliff, 1886 is redefined from 28˚44ʹS, 116˚24ʹE to 34˚11ʹS, 118˚19ʹE, and thus George Masters is identified as the original collector and January–February 1869 as the date of collection of its lectotype and paralectotype. The first larval and adult hostplant records, Eucalyptus wandoo and an unidentified Asteraceae species respectively, as well as three further distributional records from south-west Western Australia, are provided for N. chydaea and discussed. A colour photograph of its dorsal habitus is also provided, as well as a distribution map for this species. Relationships, general zoogeography and biology of all Nascio species are briefly discussed.

On the basis of new survey, knowledge of Australia’s heteropteran fauna has been shown to have a significant taxonomic impediment, requiring the description of many new lineages. In this work we provide a monographic treatment of the lace bug genus Epimixia, including a phylogenetic analysis validating its monophyly. We redescribe the genus and previously described species E. alitophrosyne Kirkaldy, E. nigriceps (Signoret), E. nigripes dysmica Drake & Ruhoff, E. nigripes nigripes (Horváth), E. veteris Drake, E. vittata Horváth and E. vulturna (Kirkaldy). Eighteen new species are described, including the first recorded species from Papua New Guinea (E. gagnei, sp. nov.), a second species from New Caledonia (E. fulva, sp. nov.) and 16 new Australian species (E. aboccidente, sp. nov., E. acclivis, sp. nov., E. albimons, sp. nov., E. allocasuarina, sp. nov., E. bicolor, sp. nov., E. caerulamons, sp. nov., E. christopherdarwini, sp. nov., E. eneabba, sp. nov., E. kimberley, sp. nov., E. leai, sp. nov., E. megacosta, sp. nov., E. minor, sp. nov., E. pilbara, sp. nov., E. schuhi, sp. nov., E. tropica, sp. nov. and E. verticordiaphila, sp. nov.). Epimixia dysmica Drake & Ruhoff is elevated to species rank, from its previous subspeciefic status within E. nigripes. This work also reports host plants for Epimixia, predominantly belonging to the Casuarinaceae, with a handful of species associated with the Myrtaceae, Proteaceae and Fabaceae. Host plants are mapped to the Epimixia phylogeny, indicating that the Casuarinaceae-affiliated Epimixia species form a subclade. Area relationships of the Epimixia species are analysed using subtree analysis, resulting in the south-west and south-east corners of Australia being sisters, relative to the Adelaide subregion, and in turn to Atherton + New Caledonia. http://zoobank.org/urn:lsid:zoobank.org:pub:E7FC4E37-517D-4AB7-A918-B9104D63AB25

The taxonomic and pest status of the species of Heliothis occurring in Australia have been examined and it is shown that two pest species have previously been confused under the name of H. armigera (Hiibner). H. amnigera has a limited distribution, mainly in coastal and subcoastal eastern Australia and in the Northern Territory. It also occurs widely in Europe, Africa, India, New Zealand, and the islands of the south-west Pacific. In North America another closely related species, probably H, umb~osus Grote, has previously been synonymized with H. armigera. Widely distributed in Australia, H. pudgera Wallengren has hitherto been referred to in the Australian economic and taxonomic literature as H. armigera. In addition, two other species, H. assulta GuenCe and H, rubrescens (Walker), occur in Australia but have not so far been recognized as pests. Descriptions and illustrations of the four species, including the male and female genitalia, and keys to the males and females, are provided. The genitalia of both sexes of the North American species are also figured.
