Balgachernes
''Balgachernes'' is a monotypic genus of pseudoscorpions in the Chernetidae family. It is endemic to Australia, and was described in 2018 by Australian arachnologist Mark Harvey. The name of the genus combines the common name 'balga' for the grasstree species ''Xanthorrhoea preissii'', with which the pseudoscorpions are associated, with the genus name ''Chernes'' (Greek: 'labourer'). Species The genus contains the single species ''Balgachernes occultus'' Harvey, 2018. The specific epithet ''occultus'' (Latin: 'cover' or 'conceal') refers to the pseudoscorpions’ preference for living among balga leaves. Description The body length of males is 2.74–3.58 mm; that of females is 2.11–3.76 mm. The colour is mainly dark reddish-brown, with the legs yellowish-brown. Distribution and habitat The species occurs in south-west Western Australia where it has been recorded from the Swan Coastal Plain, Darling Scarp and Stirling Range National Park. The type locality is As ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arthropods Of Western Australia
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cord ...

Endemic Fauna Of Australia
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Pseudoscorpion Genera
Pseudoscorpions, also known as false scorpions or book scorpions, are small, scorpion-like arachnids belonging to the order Pseudoscorpiones, also known as Pseudoscorpionida or Chelonethida. Pseudoscorpions are generally beneficial to humans because they prey on clothes moth larvae, carpet beetle larvae, booklice, ants, mites, and small flies. They are common in many environments, but they are rarely noticed due to their small size. When people see pseudoscorpions, especially indoors, they often mistake them for ticks or small spiders. Pseudoscorpions often carry out phoresis, a form of commensalism in which one organism uses another for the purpose of transport. Characteristics Pseudoscorpions belong to the class Arachnida. They are small arachnids with a flat, pear-shaped body, and pincer-like pedipalps that resemble those of scorpions. They usually range from in length.Pennsylvania State University, DepartmentEntomological Notes: Pseudoscorpion Fact Sheet/ref> The large ...

Monotypic Arachnid Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Pickering Brook, Western Australia
Pickering Brook is a suburb of Perth, Western Australia, located within the City of Kalamunda. Prior to 1949 it was a stopping place on the Upper Darling Range railway. It was named after nearby Pickering Brook. The brook is named after an early settler, Captain Edward Picking whose name was sometimes recorded as Pickering. The suburb of Pickering Brook was officially created on 12 January 1973. Part of it was formerly known as Carilla. Like nearby areas such as Karragullen, Pickering Brook is primarily made up of various family-run orchards. The suburb was seriously under threat in December 2001 from a bushfire. In June 2008, the previously named Pickering Brook National Park associated with the locality was named Korung National Park.Pamphlet ''Parks of the Perth Hills – Whats in a name?''issues by the Perth Hills District of DEC in June 2008, the name being after a Nyoongar elder at the time of European settlement – see also http://www.roleybushcare.com/bush-topic ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is ...

Darling Scarp
The Darling Scarp (), also referred to as the Darling Range or Darling Ranges, is a low escarpment running north–south to the east of the Swan Coastal Plain and Perth, Western Australia. The escarpment extends generally north of Bindoon, to the south of Pemberton. The adjacent Darling Plateau goes easterly to include Mount Bakewell near York and Mount Saddleback near Boddington. It was named after the Governor of New South Wales, Lieutenant-General Ralph Darling. History The feature was first recorded as General Darling Range by Charles Fraser, Government Botanist with Captain James Stirling aboard in March 1827. Maps from the 1830s show the scarp labelled '' General Darlings Range''; this later became ''Darling Range'', a name by which the formation was still commonly known in the late 20th century despite common understanding of it being an escarpment. There is also a tendency to identify the locations on or to the east of the scarp as being in the '' Perth Hills' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
