Шаблон:Short description Шаблон:Automatic taxobox
Hadronyche is a genus of venomous Australian funnel-web spiders that was first described by L. Koch in 1873.[1] Originally placed with the curtain web spiders, it was moved to the Hexathelidae in 1980,[2] then to the Atracidae in 2018.[3]
Description
Their size varies significantly, measuring from 1 to 5 cm. Most species in this genus, as most Mygalomorphae, have a glossy black or brown carapace. They have a very long life span for spiders, having been known to live for up to 20 years. Шаблон:Citation needed
They can be easily identified by the raised morphology of their caput (the front part of the cephalothorax). If identification is not certain, they can be distinguished from Atrax by the unmodified or blunt apophysis in their second tibia, or from Illawarra by the male tarsi, which have two instead of three ventral spine rows.[4]
Venom
While Australian funnel-web spider venom is medically significant, no human fatalities as a result have been recorded since the introduction of antivenom in 1980.[5] The venom profile of this genus is also different from the other genera from the Atracidae family.[4]
Distribution
They are found in eastern Australia from north-east Queensland to Tasmania and the Gulf Ranges region of South Australia.[4] 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 and South Australia's gulf ranges.[6]
Burrows
Hadronyche spiders usually make their burrows 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.[6]
