    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect.

  • Don't Like Spiders? Here Are 10 Reasons to Change Your Mind 7 January 2020, by Leanda Denise Mason
    Don't like spiders? Here are 10 reasons to change your mind 7 January 2020, by Leanda Denise Mason 1. Spiders haven't killed anyone in Australia for 40 years The last confirmed fatal spider bite in Australia occurred in 1979. Only a few species have venom that can kill humans: some mouse spiders (Missulena species), Sydney Funnel-webs (Atrax species) and some of their close relatives. Antivenom for redbacks (Latrodectus hasseltii) was introduced in 1956, and for funnel-webs in 1980. However, redback venom is no longer considered life-threatening. 2. Spiders save us from the world's deadliest animal Hostile reactions to spiders are harming conservation Spiders mostly eat insects, which helps control their efforts. Credit: Karim Rezk/Flickr populations. Their webs—especially big, intricate ones like our orb weavers' – are particularly adept at catching small flying insects such as mosquitoes. Australia is famous for its supposedly scary Worldwide, mosquito-borne viruses kill more spiders. While the sight of a spider may cause humans than any other animal. some people to shudder, they are a vital part of nature. Hostile reactions are harming conservation efforts—especially when people kill spiders unnecessarily. Populations of many invertebrate species, including certain spiders, are highly vulnerable. Some species have become extinct due to habitat loss and degradation. In dramatic efforts to avoid or kill a spider, people have reportedly crashed their cars, set a house on fire, and even caused such a commotion that police showed up. A pathological fear of spiders, known as arachnophobia, is of course, a legitimate condition. But in reality, we have little to fear.

    Records of tile Western AlIstralian MlIsellm Supplement No. 52: 219-223 (1995). A new species of Hypoaspis (Acarina: Laelapidae) associated with funnel-web spiders (Araneae: Hexathelidae) K.L. Strong Division of Botany and Zoology, Australian National University, Canberra, Australian Capital Territory 0200, Australia Abstract Hypoaspis barbarae sp. novo (Acarina: Laelapidae) is described from AustralIan Funnel-web Spiders of the genera Hadronyche and Atrax. INTRODUCTION Womersley, 1956, on Selenocosmia stirlingi Hogg (Mygalomorphae) and Aname sp. The mite family Laelapidae (Mesostigmata) (Mygalomorphae) from Australia, L. rainbowi mcludes many species that are parasitic on Domrow, 1975, on an unidentified spider in vertebrates, as well as others that are free-living, or Australia, L. selenocosmiae Oudemans, 1932, from have varying degrees of association with Selenocosmia javanensis (Walckenaer) from arthropods. The majority of arthropod-associated Indonesia (Sumatra), and L. minor Fain, 1989, on S. species are found in the Hypoaspidinae Vitzhum. javanensis from Indonesia (Java). A further This subfamily is usually considered to comprise association of laelapids with mygalomorph spiders the genera Hypoaspis Canestrini, 1884 sens. lat., and has been made with the description of Androlaelaps Pseudoparasitus Otidemans, 1902, with pilosus Baker, 1992, from Macrothele calpeiana approx.imately 200 and 50 described species (Walckenaer). respectively. The description of new Australian This paper describes a laelapid mite of the genus species of Hypoaspis is made difficult by the lack of Hypoaspis which is found in close association with consensus as to what defines this genus and what two genera of Funnel-web Spiders (Atrax and separates it from other closely related genera.

Such an association is new for this However, as pointed out by Evans and Till (1966) genus but adds to the collection of laelapid genera T~no~io (~982), and resolution of the existing and species associated with mygalomorph spiders.

Wese,4 1 Department of Zoology, University of Western Australia, Nedlands, Western Australia 6907, Australia (for correspondence) 2 Department of Terrestrial Invertebrates, Western Australian Museum, Francis Street, Perth, Western Australia 6000, Australia 3Lot 1984 Weller Road, Hovea, Western Australia 6071, Australia 4 current address: Halpern, Glick and Maunsell Pty Ltd, 629 Newcastle Street, Leederville, Western Australia, 6007, Australia Abstract - Nineteen genera belonging to seven families were recorded during a systematic survey of mygalomorph spiders in the southern Carnarvon Basin, a region on the central coast of Western Australia. The study was based on collections of predominantly male specimens collected from pitfall traps. Of the 60 species distinguished, 55 were undescribed. Patterns in the species composition of assemblages conformed with the gradient in wettest quarter precipitation, although localised patterns of endemism were also apparent. Species richness at quadrats exceeded that of many other habitats in Western Australia. Seasonal occurrence of wandering males (phenology) agreed with that known for respective genera in other regions, particularly of the predominantly winter breeding Idiopidae. Unusually large numbers of specimens were collected of some small-bodied nemesiids (over 70 specimens at some quadrats); this indicates an extraordinary population density possibly comparable to patches in some mesophytic forests. INTRODUCTION embracing Shark Bay and associated peninsulas, Mygalomorph spiders (trapdoor spiders) of the comprises 75 000 km2 in the mid west coastal region central and northern regions of Western Australia of Western Australia from the Minilya River in the are poorly known.
