''Missulena ignea'' is a species of mygalomorph spider in the family Actinopodidae. The species is known from Cape Range National Park, Western Australia Western Australia (WA) is the westernmost state of Australia.

Mygalomorphae
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3,000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to their creation of trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs. Description This group of spiders comprises mostly heavy-bodied, stout-legged spiders including tarantulas, Australian funnel-web spiders, mouse spiders, and various families of spiders commonly called trapdoor spiders. Like the " primitive" suborder of spiders Mesothelae, they have two pairs of book lungs, and downward-pointing chelicerae. Because of this, the two groups were once believed to be closely related. Later it was realised that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the ...

Actinopodidae
Actinopodidae is a family of mygalomorph spiders found in mainland Australia and South America usually in open forest. Species are most common in Queensland, Australia. It includes mouse spiders ('' Missulena'' species), whose bites, though rare, are considered medically significant and potentially dangerous. Description Actinopodidae has wider vision then most other Australian mygalomorphs and have a wide front to their carapace. Members of the family are stout black with species size varying from 10 mm-35 mm in length. Species have distinctively bulbous heads and jaw regions. They are oftentimes confused with funnel-web spiders. Depending on the species, the abdomen is black or dark blue with a light grey to white patch top. Legs are dark and may appear thin and the head is shiny black. Female of the family are stockier and larger. Burrow They live in soil covered burrows with a hinged top. Burrows can extent to a depth of 30 cm (12 inches). The purpose o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Range National Park
Cape Range National Park is a national park in the Gascoyne region of Western Australia, north of Perth. The park occupies the western side of the North West Cape peninsula over an area of . The nearest town is Exmouth, and directly off the coast is the Ningaloo Reef. The area resulted from a gradual uplifting from the sea floor followed by fluctuating sea levels, wind and water erosion that have slowly eroded the range and plain leaving behind a range of rugged limestone, deep canyons, and pristine beaches. There is also an eponymous locality of the Shire of Exmouth, but the boundaries of the national park and the locality are not identical. Overview The Cape is the only elevated plateau composed of limestone on the North West Coast. The range has plateaus to an elevation of and forms the backbone of the peninsula which extends as far as North West Cape. Yardie Creek, a spectacular gorge where the water is trapped by a sandbar, is located within the park. Over 700 ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia
Western Australia (WA) is the westernmost state of Australia. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a land area of , and is also the List of country subdivisions by area, second-largest subdivision of any country on Earth. Western Australia has a diverse range of climates, including tropical conditions in the Kimberley (Western Australia), Kimberley, deserts in the interior (including the Great Sandy Desert, Little Sandy Desert, Gibson Desert, and Great Victoria Desert) and a Mediterranean climate on the south-west and southern coastal areas. the state has 2.965 million inhabitants—10.9 percent of the national total. Over 90 percent of the state's population live in the South-West Land Division, south-west corner and around 80 percent live in the state capital Perth, leaving the remainder ...

Spiders Described In 2023
Spiders ( order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except Antarctica, and have become established in nearly every land habitat. , 53,034 spider species in 136 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel. However, as there is currently neither paleontological nor embryological evidence that spiders ever had a separ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiders Of Australia
Australia has a number of highly venomous spiders, including the Sydney funnel-web spider, its relatives in the family Hexathelidae, and the redback spider, whose bites can be extremely painful and have historically been linked with deaths in medical records. Most Australian spiders do not have venom that is considered to be dangerously toxic. No deaths caused by spider bites in Australia have been substantiated by a coronial inquest since 1979. There are sensationalised news reports regarding Australian spiders that fail to cite evidence. ''A Field Guide to Spiders of Australia'' published by CSIRO Publishing in 2017 featuring around 836 species illustrated with photographs of live animals, around 381 genera and 78 families, introduced significant updates to taxonomy from Ramirez, Wheeler and Dmitrov. Estimates put the total number of Australian spider species at about 10,000. Only around 3,600 have been described. Little information is known about many undiscovered species. New ...
