Taivala
''Taivala'' is a monotypic genus of jumping spiders containing the single species, ''Taivala invisitata''. It was first described by G. Peckham & Elizabeth Peckham in 1907, and is found in Sarawak, Borneo. Only females have been found, but it is thought to be closely related to ''Pseudamycus''. A female epigyne The epigyne or epigynum is the external genital structure of female spiders.

Pseudamycus
''Pseudamycus'' is a spider genus (biology), enus of the jumping spider family, Salticidae. The monotypic genus ''Taivala'' is thought to be closely related. Appearance These jumping spiders are light or colorful, sometimes iridescent. The cephalothorax is high, with steep sides of the thorax. The eyes protrude from the head, located within an orange-brown eye field. The rest of the carapace is greyish-orange, the abdomen light grey-brown with dots and light and dark streaks on the sides. The first pair of legs are dark brown with yellow tarsi, the other three pairs are reddish yellow and spiny.Salticidae.orgGenus ''Pseudamycus'' Habits They live on shrubs and other, mostly broad leaved plants, for example ginger. Distribution The ten species are found in Southeast Asia, from India to New Britain (New Guinea). Name The genus is combined of Greek ''pseudo'' "false" and the salticid genus name ''Amycus (spider), Amycus''. Species * ''Pseudamycus albomaculatus'' (Hasselt, 1882) â ...

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 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. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

Salticidae
Jumping spiders are a group of spiders that constitute the family Salticidae. As of 2019, this family contained over 600 described genera and over 6,000 described species, making it the largest family of spiders at 13% of all species. Jumping spiders have some of the best vision among arthropods and use it 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 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 anterior median pair being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider families because of the shape of the cephalothorax and their eye pa ...

George And Elizabeth Peckham
George Williams Peckham (March 23, 1845 – January 10, 1914) and Elizabeth Maria Gifford Peckham (December 19, 1854 – February 11, 1940) were a married couple who were early American teachers, taxonomists, ethologists, arachnologists, and entomologists, specializing in animal behavior and in the study of jumping spiders (family Salticidae) and wasps. Lives and careers George Peckham was born in Albany, New York in 1845. At age 18, he enlisted in the U.S. Army to fight in the American Civil War, reaching the rank of first lieutenant. After the war, he resumed his studies, obtaining a law degree from Albany Law School in 1867. After graduation, George worked at the law office of James T. Brown of Milwaukee. Not caring for the law, however, he became a student in the medical college of the University of Michigan, earning his M.D. in 1872. Rather than practice medicine, however, he chose to teach biology at East Division High School of Milwaukee, Wisconsin. In 1 ...

Sarawak
Sarawak (; ) is a States and federal territories of Malaysia, state of Malaysia. The largest among the 13 states, with an area almost equal to that of Peninsular Malaysia, Sarawak is located in northwest Borneo Island, and is bordered by the Malaysian state of Sabah to the northeast, Kalimantan (the Indonesian portion of Borneo) to the south, and Brunei in the north. The capital city, Kuching, is the largest city in Sarawak, the economic centre of the state, and the seat of the Sarawak state government. Other cities and towns in Sarawak include Miri, Malaysia, Miri, Sibu, and Bintulu. As of 2021, the population of Sarawak was estimated to be around 2.45 million. Sarawak has an equatorial climate with tropical rainforests and abundant animal and plant species. It has several prominent cave systems at Gunung Mulu National Park. Rajang River is the longest river in Malaysia; Bakun Dam, one of the largest dams in Southeast Asia, is located on one of its tributaries, the Balui River ...

Borneo
Borneo (; id, Kalimantan) is the third-largest island in the world and the largest in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, and east of Sumatra. The island is politically divided among three countries: Malaysia and Brunei in the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory. In the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The population in Borneo is 23,053,723 (2020 national censuses). Additionally, the Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. The sovereign state of Brunei, located on the north coast, comprises about 1% of Borneo's land area. A little more than half of the island is in the Northern Hemisphere, including Brunei and the Malaysian portion, while the Indonesian portion spans the Northern and Southern hemisph ...

Epigyne
The epigyne or epigynum is the external genital structure of female spiders. As the epigyne varies greatly in form in different species, even in closely related ones, it often provides the most distinctive characteristic for recognizing species. It consists of a small, hardened portion of the exoskeleton located on the underside of the abdomen, in front of the epigastric furrow and between the epigastric plates. Functions The primary function of the epigyne is to receive and direct the palpal organ of the male during copulation. The various specific forms of epigynes are correlated, in each case, with corresponding specific differences in the palpus of the male. This specialization prevents individuals of different species from mating. The epigyne covers or accompanies the openings of the spermathecae, which are pouches for receiving and retaining sperm. Frequently, the openings of the spermathecae are on the outer face of the epigyne and can be easily seen. A secondary functi ...
