This is a funnel-web spider that spends most of its life in trees. It lives in eastern Australia, and its venom is strong enough that its bites are treated as serious medical emergencies. It is one of only two Australian funnel-web species that mostly live in trees.1

Sihlala
Eastern Australia, from the Hunter River in central New South Wales to southern New South Wales1
IOstreliya neOceania
Ekhaya
It mostly lives in trees in dry sclerophyll forest, a type of dry forest with hardy eucalypt-type trees. In Tallaganda National Park and nearby areas it lives alongside Atrax sutherlandi, a funnel-web that burrows in the soil.1

Indlela yokusiqaphela

  • Glossy black carapace (the hard shell covering the front of the body)1
  • Matte black or dark brown chelicerae (the fang-bearing mouthparts) and legs1
  • Light maroon-brown to dark brown abdomen (the rear part of the body)1

Amandla etyhefu yokuluma nokuhlaba

Ukuluma

Ityhefu iphuma ngamazinyo aso etyhefu okanye ngamazinyo aso xa siluma.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

Its venom contains a peptide called Hc3a, a small protein molecule. It does not contain atraxotoxin or atraxin, which are found in the Sydney funnel-web, yet its symptoms are very similar. Symptoms can begin within 15 to 20 minutes and include heavy sweating, high blood pressure, a fast heart rate, nausea, vomiting and pain at the bite site. Fluid can build up in the lungs early on (pulmonary oedema).1

Siyingozi kangakanani ebantwini?

Three out of four recorded bites caused severe symptoms. This is a higher proportion than the Sydney funnel-web spider.1

Iindaba ezimnandi: oogqirha banamayeza (i-antivenom) okanye unyango lwale nto.1

Ukuba siyaluma

  • Applying pressure and a tourniquet can significantly delay the onset of symptoms and is a critical part of managing a bite from an Australian funnel-web spider. The venom can be successfully treated with antivenom made for the Sydney funnel-web spider.1
  • Hlamba indawo elunyiweyo uze uyipholise. Fumana uncedo lwezonyango ukuba iintlungu zinamandla okanye umntu uziva engaphilanga kakuhle.
  • EOstreliya, nakuphi na ukulunywa sisigcawu esikhulu esimnyama kuphathe njengokulunywa yi-funnel-web: Ukubopha ngoxinzelelo nokunqanda ukushukuma (pressure immobilisation): songa ibhandeji eqinileyo enwebekayo phezu kwendawo elunyiweyo uze unyuke ngelungu lonke, uliqinise ngesiplinti, kwaye ugcine umntu engashukumi kwaphela de kufike uncedo.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

  • Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
  • Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
  • Ukuba siyakuluma: hlala uzolile, musa ukushukuma, tsalela inombolo kaxakeka (112, 000, 911) okanye uye esibhedlele ngokukhawuleza. Khumbula ukuba sasikhangeleka njani, ifoto iyanceda.

Asikuzingeli. Sisebenzisa ityhefu yaso ukubamba ukutya okanye ukuzikhusela, kwaye singakhetha ukuzimela. Okungakumbi malunga nokuhlala ukhuselekile

Iinyaniso

1

Three out of four recorded bites from this spider caused severe symptoms, a higher share than the Sydney funnel-web spider.1

2

Symptoms can start within 15 to 20 minutes of a bite.1

3

Its venom does not contain atraxotoxin or atraxin, yet its symptoms are very similar to those of the Sydney funnel-web.1

4

It is one of only two Australian funnel-web species that live mainly in trees, the other being the northern tree-dwelling funnel-web (Hadronyche formidabilis).1

5

Genetic analysis shows that this spider has spread through parts of southeastern New South Wales quite recently and rapidly.1

6

The type specimen, a female collected in Sydney, was destroyed in World War II bombing, so a neotype was chosen in 2010 and is kept at the Australian Museum in Sydney.1
