Kelabita Lambir
''Kelabita'' is a small genus of southeast Asian cellar spiders. The genus was erected in 2018 for two species transferred from ''Pholcus'' after a molecular phylogenetic study of Pholcidae. It is named after the Kelabit, an ethnic group native to Borneo. They build domed webs up to above the ground, and can be distinguished by unique sclerotization, including a partially sclerotized embolus. it contains only two species: '' K. andulau'' and '' K. lambir''.

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 ...

Pholcidae
The Pholcidae are a family of araneomorph spiders. The family contains over 1,800 individual species of pholcids, including those commonly known as cellar spider, daddy long-legs spider, carpenter spider, daddy long-legger, vibrating spider, gyrating spider, long daddy, and skull spider. The family, first described by Carl Ludwig Koch in 1850, is divided into 94 genera. The common name "daddy long-legs" is used for several species, especially ''Pholcus phalangioides'', but is also the common name for several other arthropod groups, including harvestmen and crane flies. Appearance Pholcids are thin and delicate arachnids. The body, resembling the shape of a peanut, is approximately 2–10 mm (0.08–0.39 inch) in length, and the legs may be up to 50 mm (1.97 inches) long. ''Pholcus'' and ''Smeringopus'' have cylindrical abdomens and eyes arranged in two lateral groups of three and two smaller median contiguous eyes. Arrangements of eight and six ey ...

Pholcus
''Pholcus'' is a genus of spiders in the family Pholcidae, with 361 described species as of October 2021. It includes the cellar spider '' P. phalangioides'', often called the "daddy longlegs". This may cause confusion because the name "daddy longlegs" is also applied to two other unrelated arthropods: the harvestman and the crane fly. Description ''Pholcus'', like Pholcidae in general, have extremely long and thin legs. The genus can be distinguished from other pholcid genera by its large size (body length >4 mm), eight eyes, evenly domed prosoma (lacking a median furrow or pit) and cylindrical opisthosoma (longer than it is high). Habitat In the wild, ''Pholcus'' live in environments such as caves, under rocks, forest shrubs and deep limestone cracks. Synanthropic species such as ''P. phalangioides'' live in and around buildings and other disturbed habitats.

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Dayak People
The Dayak (; older spelling: Dajak) or Dyak or Dayuh are one of the native groups of Borneo. It is a loose term for over 200 riverine and hill-dwelling ethnic groups, located principally in the central and southern interior of Borneo, each with its own dialect, customs, laws, territory, and culture, although common distinguishing traits are readily identifiable. Dayak languages are categorised as part of the Austronesian languages. The Dayak were animist (Kaharingan and Folk Hindus) in belief; however, since the 19th century there has been mass conversion to Christianity as well as Islam due to the spreading of Abrahamic religions. Etymology It is commonly assumed that the name originates from the Bruneian and Melanau word for “interior people”, without any reference to an exact ethnic group. The term was adopted by Dutch and German authors as an umbrella term for any non-Muslim natives of Borneo. Thus, the difference between Dayaks and non-Dayaks natives could be un ...

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 ...

Sclerotization
Sclerotization is a biochemical process that produces the rigid shell of sclerotin that comprises an insect's chitinous exoskeleton. It is prominent in the thicker, armored parts of insects and arachnids, especially in the biting mouthparts and sclerites of scorpions and beetles. Molecular mechanism Sclerotization entails crosslinking of oxygen-reactive derivatives of dopamine. The reaction of the dopamine derivatives toward oxygen is catalyzed by diverse enzymes such as laccase, which convert the catechol groups to quinones. The resulting quinones are susceptible to nucleophilic attack by amines and thiols, which decorate the side-chains of proteins. These reactions gives rise to color (typically brown), loss of solubility, and rigidification that accompany sclerotization.{{cite journal , doi=10.1007/s00726-005-0298-2, title=When Quinones Meet Amino Acids: Chemical, Physical and Biological Consequences, year=2006, last1=Bittner, first1=S., journal=Amino Acids, volume=30, issue=3 ...

Palpal Bulb
The two palpal bulbs – also known as palpal organs and genital bulbs – are the copulatory organs of a male spider. They are borne on the last segment of the pedipalps (the front "limbs" of a spider), giving the spider an appearance often described as like wearing boxing gloves. The palpal bulb does not actually produce sperm, being used only to transfer it to the female. Palpal bulbs are only fully developed in adult male spiders and are not completely visible until after the final moult. In the majority of species of spider, the bulbs have complex shapes and are important in identification. Structure The palpal bulb of a mature male spider is borne on the last segment of the pedipalp. This segment usually has touch-sensitive hairs (setae) with nerves leading to them. The bulb itself is entirely without nerves, and hence without sensory organs and muscles, since these depend on nerves for their functioning, although some spiders have one or two muscles external to the bulb and ...
