Platycryptus Californicus
''Platycryptus'' is a genus of jumping spiders that was first described by D. E. Hill in 1979. The name comes from the Greek ''platy'' meaning flat and ''crypt'' meaning hidden, as these spiders are squat and will frequently hide in crevices. They have hairy bodies with a cryptic gray and brown color pattern. They live on or under the bark of trees, and can be found on man-made wooden structures. Species it contains four species, found only in North America, Central America, and Brazil: *'' Platycryptus arizonensis'' (Barnes, 1958) – USA *'' Platycryptus californicus'' (Peckham & Peckham, 1888) – North, Central America *'' Platycryptus magnus'' (Peckham & Peckham, 1894) – Mexico to Brazil *''Platycryptus undatus'' (De Geer, 1778) (type) – North America North America is a continent in the Northern Hemisphere, Northern and Western Hemisphere, Western hemispheres.

Platycryptus Undatus
''Platycryptus undatus'', also called the tan or familiar jumping spider, is a species of jumping spider (family Salticidae), native to North America.A guide to some of Ontario's spiders by Cole, Noah. Ontario Nature Magazine. 2017. pp. 60-61 Description Tan jumping spiders can be identified by their mottled tan coloration, thin bodies and chevron patterning on their abdomens. The tan jumping spider's thin body allows them to hide themselves under the loosened bark of trees and in other tight places. The prominent chevron-like pattern on their abdomens serves to break up their visual profile and make them more difficult to distinguish on mottled surfaces. Females of this species are between 10 and 13 mm in body length, and males rang ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles De Geer
Charles De Geer (30 January 1720 – 7 March 1778) was an entomology, entomologist, industrialist, civil servant and book collecting, book collector. He is sometimes referred to as Charles the Entomologist, to distinguish him from other relatives with the same name. Charles De Geer came from a prominent Swedish-Dutch family. Born in Sweden, he spent most of his childhood and youth in the Dutch Republic. At the age of 18 he moved back to Sweden and would spend the rest of his life there. Upon his return to Sweden, he took over the management of the ironworks of Lövstabruk. He was a successful businessman and with time became one of the richest men in Sweden, head of an early industry employing around 3,000 people. He had a successful civic career, became Marshal of the Court (Sweden), Marshal of the Court and was elevated to the rank of ''Freiherr#Swedish_and_Danish–Norwegian_title, friherre'' (baron) in 1773. De Geer had developed an interest in natural history and particula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Salticidae
Jumping spiders are a group of spiders that constitute the family (biology), family Salticidae. , this family contained over 600 species description, described genus, genera and over 6,000 described species, making it the largest family of spiderscomprising 13% of spider species. Jumping spiders have some of the best visual perception, vision among arthropods — being capable of stereoptic color vision — and use sight in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and Invertebrate trachea, tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the Anatomical terms of location, anterior median pair (the two front middle eyes) being pa ...

Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...

Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...
