Sason Hirsutum
''Sason hirsutum'' is a species of spiders in the family Barychelidae, found in Indonesia. Description Only the male has been described. Its body is about 9 mm long in total. The upper (dorsal) surface is generally light reddish brown; the lower (ventral) surface is lighter. The abdomen has a darker pattern on both surfaces. The ventral surface of the tarsus and part of the metatarsus of each leg is white. The legs are densely covered with relatively long hairs. Taxonomy ''Sason hirsutum'' was first described by Peter J. Schwendinger in 2003. The species name, ''hirsutum'', meaning "hairy", refers to the long dense hair on the legs. The male is similar to '' S. andamanicum'', but can be distinguished by a number of features, including the short, stout cuspules on the labium and maxillae, and the thinner, straight embolus of the palpal bulb. Distribution and habitat The species is only known from one of the Lingga Islands The Lingga Regency ( id, Kabupaten Lingga) ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider
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 sep ...

Barychelidae
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 42 genera. Most spiders in this family build trapdoor burrows. For example, the long '' Sipalolasma'' builds its burrow in rotted wood, with a hinged trapdoor at each end. The long ''Idioctis'' builds its burrow approximately deep, just below the high tide level, sealing the opening with a thin trapdoor. Some species avoid flooding by plugging their burrows, while others can avoid drowning by trapping air bubbles within the hairs covering their bodies. Some members of this group have a rake on the front surface of their chelicerae used for compacting burrow walls. These spiders can run up glass like tarantulas, and some can stridulate, though it isn't audible to humans. Distribution Barychelids are found in Australia, New Caledonia, South America, Africa, Madagascar, India, New Guinea, and Pacific islands. Genera , the World Spider Catalog accepts the following genera: *'' Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 a ...

Lingga Islands
The Lingga Regency ( id, Kabupaten Lingga) is a group of islands in Indonesia, located south of Singapore, along both sides of the equator, off the eastern coast of Riau Province on Sumatra island. They are south of the populated Riau Archipelago, known for the industrial island of Batam and the tourist-frequented island of Bintan, although the Lingga Islands themselves are rarely visited due to the infrequent local transportation. The equator goes through the northern tip of Lingga Island, the main island in the archipelago. Administratively they form a Regency of the Riau Islands Province with an area of 2,266.77 km2 and a population of 86,244 people at the 2010 census and 98,633 at the 2020 census.Badan Pusat Statistik, Jakarta, 2021. The regency seat lies at Daik on Lingga Island. The population are mainly Malay, Bugis and Chinese (predominantly Hakka, Teochew and Hokkien). Name Lingga derives its name from the profile of which is shaped like the Hindu linga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitun ...
