Seven species of the putatively obligately ectomycorrhizal fungal genus Rozites are described from Australian Nothofagus and myrtaceaeous forests. Rozites metallica, R. armeniacovelata, R. foetens, and R. occulta are new species associated with Nothofagus in south eastern Australia. Rozites fusipes, previously known only from New Zealand, is reported from Tasmanian Nothofagus forests. Rozites roseolilacina and R. symea are new species associated with Eucalyptus in south eastern and south western Australia respectively. The significance of these Rozites species to mycorrhizal and biogeographical theories, such as the origin of ectomycorrhizal fungi associated with myrtaceous plants in Australia are discussed. The diversity of Rozites species in Australia, which equals or exceeds that of other southern regions, furthers the notion that many species of the genus co-evolved with Nothofagus in the Southern Hemisphere. Rozites symea in Western Australia occurs well outside the current geographic range of Nothofagus. It is considered to be a relict species that has survived the shift in dominant ectomycorrhizal forest tree type from Nothofagus to Myrtaceae (local extinction of Nothofagus 4–5 million years ago), and is most likely now confined to the high rainfall zone in the south west. Data on Rozites in Australia support the concept that at least some of the present set of ectomycorrhizal fungi associated with Myrtaceae in Australia are those which successfully completed a host change from Nothofagus, and adapted to changing climate, vegetation and soil conditions during and since the Tertiary. We suggest that the ancient stock of Rozites arose somewhere within the geographical range of a Cretaceous fagalean complex of plant taxa. By the end of the Cretaceous, Rozites and the fagalean complex may have spanned the Asian–Australian region including perhaps many Southern Hemisphere regions. A northern portion of the ancestral Rozites stock gave rise to extant Northern Hemisphere Rozites species and a southern portion speciated as Nothofagus itself speciated.

South Eastern Australia

The genus Gymnopaxillus, previously known only from Chile and Argentina, has been found in south-eastern Australia. Two new species, G. nudus and G. vestitus, are described, and the generic description is emended to include hypogeous species with bilaterally symmetric spores and a peridium. Gymnopaxillus spp. are characterised by a yellow to golden-brown, bright cinnamon or ferruginous, loculate, columella-bearing gleba containing boletoid spores that appear vivid golden-yellow in KOH. Molecular phylogeny indicates that the genus is related to the Southern Hemisphere ectomycorrhizal genus Austropaxillus rather than to Paxillus and is placed in the Austropaxillaceae.

Larval Leptus (Acarina : Erythraeidae) ectoparasitic on higher insects (Neuroptera. Coleoptera. Lepidoptera. Hymenoptera) are comprehensively reviewed (Diptera were considered previously) . The new species (all from Australia) comprise: L. spinalatus (from Neuroptera); L. belicolus. L. cerambycius. L. faini. L. halli. L. heleus. L. jenseni. L. orthrius. L. tarranus. L. titinius. L. truncatus. L. utheri (all from Coleoptera); L. agrotis, L. georgeae (from Lepidoptera); and L. monteithi (from Hymenoptera). A key is given to the larvae of Leptus from Australia and New Guinea . L. agrotis is an ectoparasite of Agrotis infusa (Boisduval), the bogong moth, whose larvae are an important pasture pest in south-eastern Australia; as well as the larva, the deutonymph and adult are described. Leptus boggohoranus Haitlinger is recorded from a further New Guinea species of Coleoptera. L. charon Southcott, originally described from an Australian dipteran, is recorded as ectoparasitic on an Australian larval lepidopteran (Anthela sp., Anthelidae), as well as from adult Lepidoptera and Coleoptera. Leptus trucidatus (Hull, 1923), comb. nov., is proposed for Achorolophus trucidatus Hull, 1923, an adult from Western Australia.

The development of the cephalothoracic grooves, orientation of the chelae in life (correlated with burrowing), and modifications of the sexual characters of the males are the main attributes utilized in deducing the probable phylogeny of the Parastacidae. Geocharax, in which the cephalothoracic grooves are separated and clearly defined, the chelae are orientated in oblique planes, and the male genitalia are simple, is considered to be the most plesiomorphic genus: the species, which are only moderate burrowers, occur in the Bass Strait Basin of south-eastern Australia. The Parastacidae are considered to have originated in this one area of Australia, and to have dispersed from there to the other present day extra Australian regions of the southern hemisphere, each of the four extra Australian genera being the apomorphic sister-group of a genus occurring in this Australian subregion. The new genus Gvamastacus, with two included new species, is characterized by the extraordinarily large genital papillae of the male, and the eniarged pleura of the second abdominal segment of the female. The cephalothoracic grooves and lines are clearly defined and almost as well developed as in Geocharax.

A New Species

Known as a monotypic genus for over a century, Marmasoma White, 1916 is an endemic Australian bee fly genus belonging to the tribe Eclimini of the subfamily Bombyliinae. A new species: Marmasoma hortorum sp. nov. is described based on a series of specimens from Western Australia and South Australia. This new species can be easily distinguished from the congener by the inconspicuous pale wing markings and mostly white to pale yellow scales on the body, as well as characters of both male and female genitalia. M. sumptuosum is found in south-eastern Australia, including Tasmania, and some specimens have been collected on Kangaroo Island, South Australia. M. hortorum sp. nov. occurs in south Western Australia, and a pair of specimens has been taken just north of Port Augusta in South Australia. A key to species of Marmasoma is provided.

A new genus and species of janiroidean Asellota, Xenosella coxospinosa, is described from the mid-bathyal slope off the coast of south-eastern Australia. Following a comparison of the new species to several families of broadly similar body shape, with emphasis on monotypic Pleurocopidae, a new family, Xenosellidae, is proposed for the new species. In the course of comparing relevant taxa, the current placements of Prethura Kensley in the Santiidae and Salvatiella Müller in the Munnidae are rejected. The two genera are considered to be incertae sedis within the Asellota superfamily Janiroidea pending further studies.

South-western Western Australia is a biodiversity hotspot, with high levels of local endemism and a rich but largely undescribed terrestrial invertebrate fauna. Very few phylogeographic studies have been undertaken on south-western Australian invertebrate taxa, and almost nothing is known about historical biogeographic or cladogenic processes, particularly on the relatively young, speciose Quaternary sand dune habitats of the Swan Coastal Plain. Phylogeographic and taxonomic patterns were studied in textricellin micropholcommatid spiders belonging to the genus Raveniella Rix & Harvey. The Micropholcommatidae is a family of small spiders with a widespread distribution in southern Western Australia, and most species are spatially restricted to refugial microhabitats. In total, 340 specimens of Raveniella were collected from 36 surveyed localities on the Swan Coastal Plain and 17 non-Swan Coastal Plain reference localities in south-western Western Australia. Fragments from three nuclear rRNA genes (5.8S, 18S and ITS2), and one mitochondrial protein-coding gene (COI) were used to infer the phylogeny of the genus Raveniella, and to examine phylogeographic patterns on the Swan Coastal Plain. Five new species of Raveniella are described from Western Australia (R. arenacea, sp. nov., R. cirrata, sp. nov., R. janineae, sp. nov., R. mucronata, sp. nov. and R. subcirrata, sp. nov.), along with a single new species from south-eastern Australia (R. apopsis, sp. nov.). Four species of Raveniella were found on the Swan Coastal Plain: two with broader distributions in the High Rainfall and Transitional Rainfall Zones (R. peckorum Rix & Harvey, R. cirrata); and two endemic to the Swan Coastal Plain, found only on the western-most Quindalup dunes (R. arenacea, R. subcirrata). Two coastally restricted species (R. subcirrata, R. janineae) were found to be morphologically cryptic but genetically highly distinct, with female specimens morphologically indistinguishable from their respective sister-taxa (R. cirrata and R. peckorum). The greater Perth region is an important biogeographic overlap zone for all four Swan Coastal Plain species, where the ranges of two endemic coastal species join the northern and south-western limits of the ranges of R. peckorum and R. cirrata, respectively. Most species of Raveniella were found to occupy long, highly autapomorphic molecular branches exhibiting little intraspecific variation, and an analysis of ITS2 rRNA secondary structures among different species of Raveniella revealed the presence of an extraordinary hypervariable helix, ranging from 31 to over 400 nucleotides in length.

The 19 Indo-Pacific species of the snake-eel genus Ophichthus (family Ophichthidae, subfamily Ophichthinae) that live at or below 200 m are reviewed. Included are: Ophichthus aphotistos, O. brachynotopterus, O. echeloides, O. exourus, O. genie, O. kunaloa, O. megalops, O. mystacinus, O. serpentinus, O. urolophus, and nine new species which are described: O. alleni from 115–200 m off eastern Australia; O. aniptocheilos from 391–421 m off Tonga; O. congroides from 300 m off the Tuamotu Islands; O. hirritus from 600 m off the Seychelle Islands; O. humanni from 254–300 m off Vanuatu; O. ishiyamorum from 258–400 m off the Gulf of Aden, Somalia; O. lentiginosus from 400 m off Vanuatu and New Caledonia; O. microstictus from 362–450 m off Tonga, Fiji, and possibly New Caledonia; and O. tomioi from 300– 423 m off the Philippines, Marquesas, Fiji, and the Seychelle Islands. The range and depth distributions of the following are expanded to include: O. brachynotopterus to New Caledonia and Vanuatu between 541–580 m; O. mystacinus to Tonga, Fiji, and the Philippines between 371–824 m; and O. urolophus to Western Australia and Indonesia between 40– 420 m. An identification key is provided. Characteristics and the behavior of species of the subgenus Coecilophis, to which all treated species except O. aphotistos belong, is discussed. Ophichthys madagascariensis Fourmanoir (1961) is proposed to be a junior synonym of Pisodonophis cancrivorus (Richardson 1848).

Callococcithrips gen.n. is erected for the species Rhynchothrips fuscipennis Moulton that lives only among the protective waxy secretions of an eriococcid on Kunzea in south-eastern Australia. Larvae and adults of this thrips move rapidly amongst the sticky wax strands, and their maxillary stylets are unusually long and convoluted. Circumstantial evidence suggests that the thrips is predatory on immature stages of the eriococcid. Also transferred to this genus is Liothrips atratus Moulton, based on a single female from Western Australia.
