Most species in this genus, as most [Mygalomorphae](/source/Mygalomorphae), have a glossy black or brown [carapace](/source/carapace). They have a very long life span for spiders, having been known to live for up to 20 years. {{Citation needed|date=November 2022}} They can be easily identified by the raised morphology of their [caput](/source/Glossary_of_spider_terms) (the front part of the [cephalothorax](/source/cephalothorax)). If identification is not certain, they can be distinguished from ''[Atrax](/source/Atrax)'' by the unmodified or blunt [apophysis](/source/Glossary_of_spider_terms) in their second [tibia](/source/Glossary_of_spider_terms), or from ''[Illawarra](/source/Illawarra_wisharti)'' by the male [tarsi](/source/Glossary_of_spider_terms), which have two instead of three ventral [spine](/source/Glossary_of_spider_terms) rows.{{Cite web |last=Gray |first=Michael R. |date=2010 |title=A Revision of the Australian Funnel-web Spiders (Hexathelidae: Atracinae) |url=https://media.australian.museum/media/Uploads/Journals/19162/1556_complete.pdf |access-date=November 13, 2022 |website=Australian Museum}} == Venom == While Australian funnel-web spider venom is medically significant, no human fatalities as a result have been recorded since the introduction of [antivenom](/source/antivenom) in 1980.{{cite web |title=Australian Venom Research Unit - Funnel web spiders |url=http://www.avru.org/compendium/biogs/A000003b.htm |accessdate=2019-06-09 |publisher=University of Melbourne}} The venom profile of this genus is also different from the other genera from the [Atracidae](/source/Atracidae) family. == Distribution == They are found in [eastern Australia](/source/Eastern_states_of_Australia) from north-east [Queensland](/source/Queensland) to [Tasmania](/source/Tasmania) and the Gulf Ranges region of [South Australia](/source/South_Australia). They live primarily in the moist regions and highlands of the east coast, though they are also found in drier open forests in the Western Slopes of the [Great Dividing Range](/source/Great_Dividing_Range) and South Australia's gulf ranges.{{Cite web |first= |title=Funnel-web Spiders |url=https://australian.museum/learn/animals/spiders/funnel-web-spiders-group/australian.museum/learn/animals/spiders/funnel-web-spiders-group/ |access-date=2022-11-14 |website=The Australian Museum |language=en }}{{Dead link|date=May 2025 |bot=InternetArchiveBot |fix-attempted=yes }} == Burrows == ''Hadronyche'' spiders usually make their [burrows](/source/Burrow) under rocks or logs, usually in cool humid areas. As with most funnel web spiders, these spiders make funnel shaped webs. The webs have silk trip lines radiating from the entrance which function as a warning system, alerting the spiders to the presence of insect prey or a possible mate. In the case of seasonal rains, the burrows can flood. While these spiders are able to survive submerged for several hours by trapping air bubbles with their hair covered legs beneath their abdomens, prolonged flooding can force them to leave their burrows. They may also leave their burrow to find a mate. ==Species== {{as of|2022|03}}, it contains 32 species, all from [Australia](/source/Australia):{{cite journal| title=Gen. ''Hadronyche'' L.
