Amilaps
''Amilaps'' is a monotypic genus of jumping spiders containing the single species, ''Amilaps mayana''. It was first described in 2019 by Wayne Maddison, who originally collected the type specimen in 1983 in Teapa, Mexico. The genus was tentatively placed in the tribe Lapsiini, a division of the subfamily Spartaeinae.

Jumping Spider
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 ...

Spartaeinae
The Spartaeinae are a subfamily of the spider family Salticidae (jumping spiders). The subfamily was established by Fred R. Wanless in 1984 to include the groups Boetheae, Cocaleae, Lineae, Codeteae and Cyrbeae, which in turn were defined by Eugène Simon. The Spartaeinae are palaeotropical, with an exceptional diversity in the Malaysian and Indonesian archipelagos. They are unusual salticids that are considered basal to the phylogenetic tree of jumping spiders. Like the Lyssomaninae they lack many derived features that the Salticinae possess. Spartaeinae usually have large posterior median eyes. However, these were reduced in the genera ''Cyrba'', ''Gelotia'' and ''Wanlessia''. Genera In 2015, Spartaeinae was divided into three tribes with 29 genera. One has been added since.

Wayne Maddison
Wayne Paul Maddison (born 1958) is a Canadian evolutionary biologist, arachnologist, and biological illustrator. He is Canada Research Chair in Biodiversity and a professor at the departments of zoology and botany at the University of British Columbia, and the Director of the Spencer Entomological Collection at the Beaty Biodiversity Museum. Education and career Maddison was born in London, Ontario and his interests in studying spiders started while he was a teenager exploring Lake Ontario. Maddison studied zoology at the University of Toronto, where he obtained his BSc in 1980. He went on to study at Harvard University in the Department of Organismic and Evolutionary Biology, where he obtained his PhD in 1988 under the supervision of Herbert W. Levi. He was a NSERC postdoctoral fellow at the University of California, Berkeley from 1988 to 1990, where he worked with Montgomery Slatkin.

Monotypic Taxon
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 Genus, 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 o ...

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 ...

Type Specimen
In biology, a type is a particular wikt:en:specimen, 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 (mathematics), 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 ...

Teapa Municipality
Teapa is a Municipalities of Tabasco, municipality in the List of states of Mexico, Mexican state of Tabasco. The municipal seat is the city of Teapa.

Spiders Of Mexico
Spiders (order Araneae) are air-breathing arthropods that have eight limbs, 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 Antarctica, and have become established in nearly every land habitat. , 53,034 spider species in 136 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
