Beutelius Reidi
''Beutelius'' is a small genus of ommatid beetles native to Australia. It is only one of three extant genera in the family, alongside ''Tetraphalerus'' and '' Omma''. It currently contains 4 species, three of which were originally assigned to ''Omma'' and it is distinguished from ''Omma'' by the presence of flattened, ribbed scales covering most areas, as well as longer maxillary and labial palps, and an anteriorly depressed gulamentum. *''Beutelius mastersi'' (MacLeay, 1871) inland New South Wales and Queensland *'' Beutelius reidi'' Escalona ''et al'', 2020 northwest New South Wales *'' Beutelius rutherfordi'' (Lawrence, 1999) Mallee Woodlands and Shrublands *''Beutelius sagitta ''Beutelius'' is a small genus of ommatid beetles native to Australia.

Ommatidae
The Ommatidae are a family of beetles in the suborder Archostemata. The Ommatidae are considered the extant beetle family that has most ancestral characteristics. There are only seven extant species, confined to Australia and South America. However, the geographical distribution was much wider during the Mesozoic spanning across Eurasia and Australia, suggesting that they were widespread on Pangea. So far, over 26 extinct genera containing over 170 species of these beetles have been described. Three extant genera have been assigned to this family: ''Omma,'' ''Tetraphalerus'' and '' Beutelius''. The family is considered to be a subfamily of Cupedidae by some authors, but have been found to be more closely related to Micromalthidae in molecular phylogenies. A close relationship with Micromalthidae is supported by several morphological characters, including those of the mandibles and male genitalia. Due to their rarity, their ecology is obscure, it is likely that their larvae feed o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly har ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australia
Australia, officially the Commonwealth of Australia, is a sovereign ''Sovereign'' is a title which can be applied to the highest leader in various categories. The word is borrowed from Old French , which is ultimately derived from the Latin , meaning 'above'. The roles of a sovereign vary from monarch, ruler or ... country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. With an area of , Australia is the largest country by area in Oceania and the world's sixth-largest country. Australia is the oldest, flattest, and driest inhabited continent, with the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, with deserts in the centre, tropical Forests of Australia, rainforests in the north-east, and List of mountains in Australia, mountain ranges in the south-east. The ancestors of Aboriginal Australians began arriving from south east Asia approx ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Omma
''Omma'' is a genus of beetles in the family Ommatidae. ''Omma'' is an example of a living fossil. The oldest species known, ''O. liassicum'', lived during the final stage of the Triassic (Rhaetian), over 200 million years ago, though the placement of this species in ''Omma'' has been questioned. Numerous other fossil species are known from the Jurassic and Cretaceous of Europe and Asia. The only living species is ''Omma stanleyi'', which is endemic to Australia. Three other extant species endemic to Australia that were formerly part of this genus were moved to the separate genus ''Beutelius'' in 2020''.'' ''Omma stanleyi'' is strongly associated with wood, being found under ''Eucalyptus'' bark and exhibiting thanatosis when disturbed. Its larval stage and many other life details are unknown due to its rarity. Males are typically 14–20 mm in length, while females are 14.4-27.5 mm. ''Omma stanleyi'' occurs throughout eastern Australia from Victoria to Central Queenslan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect Mouthparts
Insects have mouthparts that may vary greatly across insect species, as they are adapted to particular modes of feeding. The earliest insects had chewing mouthparts. Most specialisation of mouthparts are for piercing and sucking, and this mode of feeding has evolved a number of times idependently. For example, mosquitoes and aphids (which are true bugs) both pierce and suck, however female mosquitoes feed on animal blood whereas aphids feed on plant fluids. Evolution Like most external features of arthropods, the mouthparts of Hexapoda are highly derived. Insect mouthparts show a multitude of different functional mechanisms across the wide diversity of insect species. It is common for significant homology to be conserved, with matching structures forming from matching primordia, and having the same evolutionary origin. However, even if structures are almost physically and functionally identical, they may not be homologous; their analogous functions and appearance might be ...

Mallee Woodlands And Shrublands
Mallee Woodlands and Shrublands is one of 32 List of Major Vegetation Groups in Australia, Major Vegetation Groups defined by the Australian Government Department of the Environment and Energy. Description "Mallee (habit), Mallee" refers to the growth habit of a group of (mainly) eucalypt species that grow to a height of , have many stems arising from a lignotuber and have a leafy canopy that shades 30–70% of the ground. The term is also applied to a vegetation association where these mallee eucalypts grow, on land that is generally flat without hills or tall trees and where the climate is semi-arid. Of the 32 Major Vegetation Groups classified under the National Vegetation Information System, "Mallee Woodlands and Shrublands" (MVG14): * are semi-arid areas dominated by mallee eucalypts; * may also have co-dominant species of ''Callitris'', ''Melaleuca'', ''Acacia'' and ''Hakea''; * have an open tree or shrub layer with more than 10% foliage cover and more than 20% Crown (bota ...

Endemic Fauna Of Australia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
