Periegops Suterii
''Periegops suterii'' is a species of spider in the genus ''Periegops'' that is Endemism, endemic to the South Island of New Zealand.Vink, CJ; Dupérré, N; Malumbres-Olarte, J 2013. Periegopidae (Arachnida: Araneae). ''Fauna of New Zealand 70'', 41 pages. Taxonomy ''Periegops suteria'' was first described in 1892 by Arthur T Urquhart and was placed in the ''Segestria (spider), Segestria'' genus''.'' Specimens for this description were collected from Port Hills near Christchurch. Independently, Eugène Simon, Eugene Simon described ''Periegops hirsutus'' in 1893, which was also the first description of the ''Periegops genus''. In 1935, ''Segestria suteria'' was moved to the ''Periegops'' genus by Elizabeth B. Bryant, Elizabeth Bangs Bryant after examining Type (biology), types sent to her from the Canterbury Museum, Christchurch, Canterbury Museum. In 1946, ''P. hirsutus'' was recognized as a synonym of ''P. suterii'' by George Chamberlain. Description Like all members of the ...

Periegops
''Periegops'' is a genus of spiders with six eyes instead of the usual eight. It is the only genus in its Family (biology), family (Periegopidae) and has three described species. It was long considered to be members of Sicariidae or Segestriidae until Raymond Robert Forster, Raymond Forster elevated them to the family level in 1995. Taxonomy ''Periegops'' was first described in 1893 by Eugène Simon, Eugene Simon from a specimen of ''P. hirsutus'' (A synonym of ''P. suterii'').Simon, E. (1893a). ''Histoire naturelle das araignées''. Paris 1, 257-488. doi:10.5962/bhl.title.51973 Description This genus of spider has only six eyes, as opposed to eight, which is typical for spiders. Body length varies from 5.9mm to 10mm depending on species and sex. Carapace is an orange colour and is darker on the anterior side. Abdomen is brown or creamy brown and usually have a chevron pattern. The family can be distinguished by the pattern of eye positions, which are in three clusters of two ...

Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Spiders Described In 1892
Spiders (order (biology), order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude spider silk, silk. They are the largest order of arachnids and rank seventh in total species diversity among all Order (biology), orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 Family (biology), families have been recorded by Taxonomy (biology), 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 segmentation (biology), segments are fused into two Tagma (biology), tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical Gl ...

Nocturnality
Nocturnality is an animal behavior characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. Some animals, such as cats and ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsiers and some owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intense sunlight. Diurnal animals, including squirrels and songbirds, are active d ...

Dragline Silk
Spider silk is a protein fibre spun by spiders. Spiders use their silk to make Spider web, webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. They can also use their silk to suspend themselves, to Ballooning (spider), float through the air, or to glide away from predators. Most spiders vary the thickness and stickiness of their silk for different uses. In some cases, spiders may even use silk as a source of food. While methods have been developed to collect silk from a spider by force, it is difficult to gather silk from many spiders compared to silk-spinning organisms such as Sericulture, silkworms. All spiders produce silk, and even in non-web building spiders, silk is intimately tied to courtship and mating. Silk produced by females provides a transmission channel for male vibratory courtship signals, while webs and draglines provide a substrate for female sex pheromones. O ...

Relict Species
In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past. A relictual population is a population currently inhabiting a restricted area whose range was far wider during a previous geologic epoch. Similarly, a relictual taxon is a taxon (e.g. species or other lineage) which is the sole surviving representative of a formerly diverse group. Definition A relict (or relic) plant or animal is a taxon that persists as a remnant of what was once a diverse and widespread population. Relictualism occurs when a widespread habitat or range changes and a small area becomes cut off from the whole. A subset of the population is then confined to the available hospitable area, and survives there while the broader population either shrinks or evolves divergently. This phenomenon differs from endemism in that the range of the population was not always restricted to the local region. In other words, the species or group did ...

Riccarton Bush
Riccarton is a suburb of Christchurch. It is due west of the city centre, separated from it by Hagley Park. Upper Riccarton is to the west of Riccarton. History On 12 April 1840, the ship ''Sarah and Elizabeth'' landed Herriot, McGillivray, Ellis, Shaw (and wife) and McKinnon (with his wife and child) who established a farm at Riccarton. They were the first European settlers on the plains." In January 1841, they abandoned their attempt to farm in the area. Riccarton House was the homestead commissioned by Jane Deans in circa 1855. The Deans brothers, who along with the Gebbies and the Mansons were the second group of Europeans to settle in Christchurch on the same site as the first group in 1843. Their original cottage is on the grounds, moved twice from its original position. Riccarton House is now a restaurant and function centre, and conducts regular tours. The Deans brothers, John and William, named the suburb after the parish in Ayrshire, Scotland, in which they were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banks Peninsula
Banks Peninsula is a peninsula of volcanic origin on the east coast of the South Island of New Zealand. It has an area of approximately and encompasses two large harbours and many smaller bays and coves. The South Island's largest city, Christchurch, is immediately north of the peninsula. Geology Banks Peninsula forms the most prominent volcanic feature of the South Island, similar to — but more than twice as large as — the older Dunedin volcano (Otago Peninsula and Harbour) to the southwest. Geologically, the peninsula comprises the eroded remnants of two large (Lyttelton formed first, then Akaroa), and the smaller Mt Herbert Volcanic Group. These formed due to intraplate volcanism between approximately eleven and eight million years ago (Miocene) on a continental crust. The peninsula formed as offshore islands, with the volcanoes reaching to about 1,500 m above sea level. Two dominant craters formed Lyttelton and Akaroa Harbours. The Canterbury ...

Chelicerae
The chelicerae () are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders. Commonly referred to as "jaws", chelicerae may be shaped as either articulated fangs, or similarly to pincers. Some chelicerae, such as those found on nearly all spiders, are hollow and contain (or are connected to) venom glands, and are used to inject venom into prey or a perceived threat. In ''Pisaurina mira'', also known as the nursery web spider, the chelicerae are utilized to snatch the prey once it becomes within reach, facilitating the "sit-and-wait ambush predator" behavior. Both pseudoscorpions and harvestmen have structures on their chelicerae that are used for grooming (papillae in pseudoscorpions, cheliceral teeth in Opiliones). Types Chelicerae can be divided into three kinds: jackknife chelicerae, scissor chelicerae, and 3-segmented chelate chelicerae. Jackknife chelicerae The jackknife chelicera is subchelate (with ...

Canterbury Museum, Christchurch
The Canterbury Museum is a museum located in the central city of Christchurch, New Zealand, in the city's Cultural Precinct. The museum was established in 1867 with Julius von Haast – whose collection formed its core – as its first director. The building is registered as a "Historic Place – Category I" by Heritage New Zealand. Directors The title curator and director has been used interchangeably during the history of Canterbury Museum. Von Haast was the museum's inaugural director; Haast died in 1887. Following Haast's death, Frederick Hutton was acting director until Henry Ogg Forbes took on a permanent position in December 1888 upon his return from England. In August 1892, Forbes permanently moved to England, and Hutton was appointed full director from May 1892 until October 1905. Hutton applied for leave to travel to England, and Charles Chilton was acting director from March 1905; Hutton died on his return journey from England and Chilton retained his acting role un ...

Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
