Revision of the dung beetle genus Temnoplectron Westwood (Coleoptera: Scarabaeidae: Scarabaeini)

Temnoplectron Westwood is revised and five new species described, four from North Queensland: cooki, finnigani, lewisense, monteithi, one from New Guinea: wareo. Temnoplectron reyi Paulian is removed from synonymy with T. politulum Macleay, Temnoplectron laevigatum Matthews is placed in synonymy with T. boucomonti Paulian, T. heurni Paulian and Z howdeni Paulian are synonymised with Z atropolitum Gillet, and T. major Paulian is recognised in Australia for the first time. All known species are redescribed. A key is provided for the 19 species of Temnoplectron and new distribution records are noted. A cladistic analysis of the genus is presented, the results of which suggest at least two origins for flightlessness in the genus. The biogeography of Temnoplectran is discussed with reference to isolation of rainforest blocks during periods of maximum aridity.

Revision of a Australoxenella Howden & Storey in Australia (Coleoptera: Scarabaeidae: Aphodiinae)

Australoxeneffa Howden & Storey, the only Australian member of the aphodiine tribe Stereomerini, is revised. Eleven species are described of which the following are new: concinna, kalpara, midgee, mirreen, moogoon, peckonim, teeta, wurrook, zborowskii. Relationships between species are discussed. Most new specimens were taken in flight interception traps. No information is available on the biology of these suspected termitophiles.

Australian and Thai isolates of Burkholderia pseudomallei are distinct by multilocus sequence typing: Revision of a case of mistaken identity

A recent study using multilocus sequence typing (MLST) of Burkholderia pseudomallei isolates found a sequence type (ST60) to be common to both Thailand and Australia, contradicting earlier studies showing complete distinction between isolates from these regions. The ST60 isolates reportedly from Australia had been obtained for MLST from United Kingdom and U.S. collections. We have located and characterized the original Australian isolates; they were collected in 1983, and they are neither ST60 nor B. pseudomallei isolates. The B. pseudomallei MLST database has been corrected, and there is no ST common to isolates verified as obtained from Australia or from Thailand.

Revision of the Australian stiletto fly genus Acatopygia Krober (Diptera: Therevidae: Agapophytinae)

The endemic Australian stiletto fly genus Acatopygia Krober is revised. Acatopygia pulchella Krober and Acatopygia paradoxa (Krober) are redescribed and a neotype for A. paradoxa designated. A new species, Acatopygia olivacea sp. nov., is described and a key to Acatopygia species is presented.

Australian gall-inducing scale insects on Eucalyptus: revision of Opisthoscelis Schrader (Coccoidea, Eriococcidae) and descriptions of a new genus and nine new species.

We revise the genus Opisthoscelis Schrader, and erect the genus Tanyscelis gen. n. with Opisthoscelis pisiformis Froggatt as its type species. Species of both genera induce sexually dimorphic galls on Eucalyptus (Myrtaceae) in Australia, with Opisthoscelis subrotunda Schrader also in Papua New Guinea. We synonymise the following taxa (junior synonym with senior synonym): Opisthoscelis fibularis Froggatt, syn. n. with Opisthoscelis spinosa Froggatt; Opisthoscelis recurva Froggatt, syn. n. with Opisthoscelis maculata Froggatt; Opisthoscelis globosa Froggatt, syn. n. (=Opisthoscelis ruebsaameni Lindinger) with Opisthoscelis convexa Froggatt; and Opisthoscelis mammularis Froggatt, syn. n. with Opisthoscelis verrucula Froggatt. We transfer seven Opisthoscelis species to Tanyscelis as Tanyscelis conica (Fuller), comb. n., Tanyscelis convexa (Froggatt), comb. n., Tanyscelis maculata (Froggatt), comb. n., Tanyscelis maskelli (Froggatt), comb. n., Tanyscelis pisiformis (Froggatt), comb. n., Tanyscelis spinosa (Froggatt), comb. n., and Tanyscelis verrucula (Froggatt), comb. n. We redescribe and illustrate the adult female of each named species of Opisthoscelis for which the type material is known, as well as the first-instar nymph of the type species of Opisthoscelis (Opisthoscelis subrotunda) and Tanyscelis (Opisthoscelis pisiformis). We describe four new species of Opisthoscelis: Opisthoscelis beardsleyi Hardy & Gullan, sp. n., Opisthoscelis thurgoona Hardy & Gullan, sp. n., Opisthoscelis tuberculata Hardy & Gullan, sp. n., and Opisthoscelis ungulifinis Hardy & Gullan, sp. n., and five new species of Tanyscelis: Tanyscelis grallator Hardy & Gullan, sp. n., Tanuscelis megagibba Hardy & Gullan, sp. n., Tanyscelis mollicornuta Hardy & Gullan, sp. n., Tanyscelis tripocula Hardy & Gullan, sp. n., and Tanyscelis villosigibba Hardy & Gullan, sp. n. We designate lectotypes for Opisthoscelis convexa, Opisthoscelis fibularis, Opisthoscelis globosa Froggatt, Opisthoscelis maculata, Opisthoscelismammularis, Opisthoscelis maskelli, Opisthoscelis pisiformis, Opisthoscelis recurva, Opisthoscelis serrata, Opisthoscelis spinosa, and Opisthoscelis verrucula. As a result of our taxonomic revision, Opisthoscelis has six species and Tanyscelis has 12 species. We describe the galls of females for all 18 species and galls of males for 10 species of Opisthoscelis and Tanyscelis, and provide photographs of the galls for most species. A key to the adult females of the species of both genera is included.

Taxonomic revision of Ustilago, Sporisorium and Macalpinomyces

Morphological characters within the Ustilago-Sporisorium-Macalpinomyces complex are defined explicitly. The genera Sporisorium and Anthracocystis are emended to reflect morphological synapomorphies. Three new genera, Langdonia, Stollia and Triodiomyces are described based on soral synapomorphies and host classification. The new classification of the Ustilago-Sporisorium-Macalpinomyces complex incorporates 142 new taxonomic combinations.

Biodiversity of Australian smut fungi.

There are about 250 species of smut fungi known from Australia of which 95 are endemic. Fourteen of these endemic species were first collected in the period culminating with the publication of Daniel McAlpine's revision of Australian smut fungi in 1910. Of the 68 species treated by McAlpine, 10 were considered to be endemic to Australia at that time. Only 23 of the species treated by McAlpine have names that are currently accepted . During the following eighty years until 1990, a further 31 endemic species were collected and just 11 of these were named and described in that period. Since 1990, 50 further species of endemic smut fungi have been collected and named in Australia . There are 115 species that are restricted to either Australia or to Australia and the neighbouring countries of Indonesia, New Zealand, Papua New Guinea and the Philippines . These 115 endemic species occur in 24 genera, namely Anthracoidea (1 species), Bauerago (1), Cintractia (3), Dermatosorus (1), Entyloma (3), Farysporium (1), Fulvisporium (1), Heterotolyposporium (1), Lundquistia (1), Macalpinomyces (4), Microbotryum (2), Moreaua (20), Pseudotracya (1), Restiosporium (5), Sporisorium (26), Thecaphora (2), Tilletia (12), Tolyposporella (1), Tranzscheliella (1), Urocystis (2), Ustanciosporium (1), Ustilago (22), Websdanea (1) and Yelsemia (2). About a half of these local and regional endemic species occur on grasses and a quarter on sedges . The northern tropical savannah region of Australia offers most promise for the discovery of new endemic species . The agricultural, quarantine and environmental significance to Australia of some introduced species is discussed.

Coriza infecciosa: revisión de métodos de diagnóstico y vacunas

La coriza infecciosa es una enfermedad respiratoria aguda de las gallinas domesti- cas causada por la bacteria Haemophilus parugallinarum. Excepcionalmente pueden enfermarse tambien los faisanes y gallinas de Guinea. El H. paragallinarum infecta al ave por via respiratoria y luego de un cor- to periodo de incubation, que varia entre 1 a 3 dias, produce una enfermedad que se manifiesta por inflamacion catarral de los senos paranasales. Este cuadro puede estar asociado a inflamacion de los barbillones, conjuntivitis o queratitis. Los casos de neu- nionia y aerosaculitis son menos frecuentes pero tambien suelen ocurrir en las infeccio- nes puras por estos hemofilos. En las gallinas en produccion causa alta morbilidad, baja o nula mortalidad y una importante perdida en la produccion de huevos, la que generalmente oscila entre 10% y 40%. En pollos parrilleros puede cau- sar un cuadro descrito como «cabeza hin- chada» y ocasionalmente tambien producir septicemia y muerte (48). Esta bacteria ge- neralmente se asocia con otros agentes bacterianos, viricos o parasitarios y cuan- do esto ocurre se agrava el curso de la en- fermedad. Entre los agentes bacterianos mas comunes deben mencionarse los mycoplasinas y las pasteurelas. Cuando H . paragallinarum se asocia con otros agentes esta enfermedad se denomina .«coriza infec- ciosa complicada» (48). En esta recopilacion se aportaran deta- lles sobre la clasificacion, identificacion y serotipificacion del agente causal. Tambien se resumira la informacion disponible sobre nuevos metodos de diagnostico y programas de vacunacion para prevenir esta enferme-dad. A lo largo de esta revision se hara re-ferencia a los hemofilos aviarios que, para el proposito de este trabajo, seran definidos como organisnios gram negativos aislados de aves y que necesariamente requieren factores de crecimiento in vitro. Los dos factores que pueden ser requeridos por los hemofilos para su crecimiento in vitro son hemina (factor X) y/o nicotin-adenin-dinucleirtido (NAD o factor V).

Concordant molecular and phenotypic data delineate new taxonomy and conservation priorities for the endangered mountain yellow-legged frog

The mountain yellow-legged frog Rana muscosa sensu lato, once abundant in the Sierra Nevada of California and Nevada, and the disjunct Transverse Ranges of southern California, has declined precipitously throughout its range, even though most of its habitat is protected. The species is now extinct in Nevada and reduced to tiny remnants in southern California, where as a distinct population segment, it is classified as Endangered. Introduced predators (trout), air pollution and an infectious disease (chytridiomycosis) threaten remaining populations. A Bayesian analysis of 1901 base pairs of mitochondrial DNA confirms the presence of two deeply divergent clades that come into near contact in the Sierra Nevada. Morphological studies of museum specimens and analysis of acoustic data show that the two major mtDNA clades are readily differentiated phenotypically. Accordingly, we recognize two species, Rana sierrae, in the northern and central Sierra Nevada, and R. muscosa, in the southern Sierra Nevada and southern California. Existing data indicate no range overlap. These results have important implications for the conservation of these two species as they illuminate a profound mismatch between the current delineation of the distinct population segments (southern California vs. Sierra Nevada) and actual species boundaries. For example, our study finds that remnant populations of R. muscosa exist in both the southern Sierra Nevada and the mountains of southern California, which may broaden options for management. In addition, despite the fact that only the southern California populations are listed as Endangered, surveys conducted since 1995 at 225 historic (1899-1994) localities from museum collections show that 93.3% (n=146) of R. sierrae populations and 95.2% (n=79) of R. muscosa populations are extinct. Evidence presented here underscores the need for revision of protected population status to include both species throughout their ranges.
