Taxonomy and namingGerman naturalist Ludwig Koch described the southern tree funnel-web from a female spider collected in Sydney, and erected the genus Hadronyche in 1873. The type specimen was housed at the State Museum of Natural History Stuttgart and destroyed during bombing in World War II. A neotype was subsequently selected in 2010 and is housed at the Australian Museum in Sydney.[1] DescriptionThe southern tree funnel-web has a glossy black carapace, and matte black or dark brown chelicerae and legs, and light maroon-brown to dark brown abdomen.[1] Distribution and habitatThe southern tree funnelweb is found in eastern Australia from the Hunter River in central New South Wales to southern New South Wales. This and the northern tree funnel-web (Hadronyche formidabilis) are the only two species of funnel-web that live predominantly in trees.[1] It inhabits dry sclerophyll forest.[1] In Tallaganda National Park and its surrounds in southeastern New South Wales, the southern tree funnel-web co-occurs with the funnel-web species Atrax sutherlandi, which burrows exclusively in the soil, in contrast with the former species' preference for logs. Genetic analysis shows that the southern tree funnel-web has recently rapidly spread through the area.[2] ToxicityA high proportion of bites from the southern tree funnel-web spider—three out of four recorded cases—result in severe symptoms of envenomation. The venom can be successfully treated with the antivenom for the related Sydney funnel-web (Atrax robustus).[3] Symptoms of envenomation can occur within 15–20 minutes. Applying pressure and a tourniquet can significantly delay the onset of symptoms and remains a critical part of management of a spider bite. Despite the venom lacking the atraxotoxin or atraxin of A. robustus, the symptoms are very similar to those from a Sydney funnel-web bite. Common symptoms include diaphoresis (profuse sweating), hypertension (elevated blood pressure), sinus tachycardia (elevated heart rate), nausea, vomiting and local pain at the bite site. Pulmonary oedema (fluid build-up in the lungs) often comes on early.[4] References1. ^1 2 3 {{cite journal|last=Gray|first=Michael R.|title=A revision of the Australian funnel-web spiders (Hexathelidae: Atracinae)|journal=Records of the Australian Museum|date=24 November 2010|volume=62|issue=3|pages=285–392|doi=10.3853/j.0067-1975.62.2010.1556|issn=0067-1975|url=http://australianmuseum.net.au/Uploads/Journals/19162/1556_complete.pdf}} 2. ^{{cite journal|last=Beavis|first=Amber|year=2011|title=Microhabitat preferences drive phylogeographic disparities in two Australian funnel web spiders|journal= Biological Journal of the Linnean Society|volume=104|issue=4|pages=805–19|issn=0024-4066|doi=10.1111/j.1095-8312.2011.01753.x}} 3. ^{{cite journal |vauthors=Isbister G, Gray M, Balit C, Raven R, Stokes B, Porges K, Tankel A, Turner E, White J, Fisher M | title = Funnel-web spider bite: a systematic review of recorded clinical cases | journal = Med J Aust | volume = 182 | issue = 8 | pages = 407–11 | year = 2005 | pmid = 15850438|url=https://www.mja.com.au/journal/2005/182/8/funnel-web-spider-bite-systematic-review-recorded-clinical-cases?iframe=true}} 4. ^{{cite journal|vauthors=Miller MK, Whyte IM, White J, Keir PM |year=2000|title=Clinical features and management of Hadronyche envenomation in man.|journal=Toxicon|volume=38|issue=3|pages=409–27|pmid=10669029|doi=10.1016/S0041-0101(99)00171-3}} External links{{Wikispecies-inline}}{{Commons-inline}}{{Taxonbar|from=Q2547419}} 4 : Mygalomorphae|Spiders of Australia|Venomous spiders|Spiders described in 1873 |
