Cyriocosmus Elegans
''Cyriocosmus elegans'' is a spider species in the genus ''Cyriocosmus'' and the family Theraphosidae (tarantulas) found in Venezuela, Trinidad and Tobago. Basic Information Cyriocosmus elegans is a fossorial species of tarantula that is known to reach maturity quickly, sometimes in a year's time. Adult size is around 1.5" to 2" diagonal leg span (DLS), from leg I on one side to leg IV on the opposite side. Second instar spiderlings are around 1/16" to 1/8" DLS and will readily accept pre-killed feeders, fruit flies, or even a cricket leg.

Eugène Simon
Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider taxonomist in history, describing over 4,000 species. Work on spiders His most significant work was ''Histoire Naturelle des Araignées'' (1892–1903), an encyclopedic treatment of the spider genera of the world. It was published in two volumes of more than 1000 pages each, and the same number of drawings by Simon. Working at the Muséum National d'Histoire Naturelle in Paris, it took Simon 11 years to complete, while working at the same time on devising a taxonomic scheme that embraced the known taxa. Simon described a total of 4,650 species, and as of 2013 about 3,790 species are still considered valid. The International Society of Arachnology offers a Simon Award recognising lifetime achievement. The Eocene fossil spider species '' Cenotextricella simoni'' was named in his ...

Cyriocosmus
''Cyriocosmus'' is a genus of tarantulas that was first described by Eugène Louis Simon in 1903. They are small to medium spiders, with a bicolored or one same color carapace. Diagnosis It differs from all other tarantulas by the paraembolic apophysis in the palpal bulbs of males, and a spermatheca with two spiral receptacles, which usually end in a caliciform or globular extension. Except for C. nogueiranetoi, which owns a S shape extension. All the species also own type 3 urticating hairs. Species it contains twenty-three species, found in South America, on Tobago, and Trinidad: *'' Cyriocosmus aueri'' Kaderka, 2016 – Peru *'' Cyriocosmus bertae'' Pérez-Miles, 1998 – Brazil *'' Cyriocosmus bicolor'' (Schiapelli & Gerschman, 1945) – Brazil *'' Cyriocosmus blenginii'' Pérez-Miles, 1998 – Bolivia *''Cyriocosmus elegans'' (Simon, 1889) – Venezuela, Trinidad and Tobago *'' Cyriocosmus fasciatus'' ( Mello-Leitão, 1930) – Brazil *'' Cyriocosmus fernandoi'' Fukushi ...

Theraphosidae
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. , 1,040 species have been identified, with 156 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes. Overview Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.Pomeroy, R. (2014, February 4). Pub.

Fossorial
A fossorial () animal is one adapted to digging which lives primarily, but not solely, underground. Some examples are badgers, naked mole-rats, clams, meerkats, and mole salamanders, as well as many beetles, wasps, and bees. Prehistoric evidence The physical adaptation of fossoriality is widely accepted as being widespread among many prehistoric phyla and taxa, such as bacteria and early eukaryotes. Furthermore, fossoriality has evolved independently multiple times, even within a single family. Fossorial animals appeared simultaneously with the colonization of land by arthropods in the late Ordovician period (over 440 million years ago). Other notable early burrowers include ''Eocaecilia'' and possibly ''Dinilysia''. The oldest example of burrowing in synapsids, the lineage which includes modern mammals and their ancestors, is a cynodont, ''Thrinaxodon liorhinus'', found in the Karoo of South Africa, estimated to be 251 million years old. Evidence shows that this ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

Spiders Described In 1889
Spiders (order Araneae) are air-breathing arthropods that have eight legs, 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 for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 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 separate th ...
