Gasteracantha Interrupta
''Gasteracantha interrupta'' is a species of spiny orb-weaver spider in the genus '' Gasteracantha''. It is black and white in color, and it occurs in the Lesser Sundas and Sulawesi in Indonesia. Description Female ''Gasteracantha interrupta'' spiders have hardened, shell-like abdomens that are black and white in color and armed with six spines. Friedrich Dahl described this species in 1914 based on five specimens from Sulawesi and Lombok. Dahl distinguished this species from another black-and-white species, the wide-ranging ''Gasteracantha kuhli ''Gasteracantha kuhli'' is a species of spiny orb-weaver spider in the genus ''Gasteracantha'', widespread from India to Japan, the Philippines, and Java in Indonesia Indonesia, officially the Republic of Indonesia, is a country in Southe ...'', based on a plain white central area on the dorsal side of the abdomen and details of the sigilla.

Friedrich Dahl
Karl Friedrich Theodor Dahl (June 24, 1856 in Rosenhofer Brök north of Dahme, Holstein – June 29, 1929 in Greifswald) was a German zoologist, and in particular an arachnologist. The son of a farmer, Dahl studied at the universities of Leipzig, Freiburg, Berlin and Kiel. His dissertation (1884) was "''Beiträge zur Kenntnis des Baus und der Funktion der Insektenbeine''". He became a '' Privatdozent'' in 1887; with a habilitation thesis "''Ueber die Cytheriden der westlichen Ostsee''". Around this time he traveled to the Baltic states and (1896–1897) to the Bismarck Archipelago near New Guinea. He was also interested in biogeography. On April 1, 1898 Dahl became curator of arachnids at the ''Museum für Naturkunde'' in Berlin, where he worked under his former teacher, the then museum director Karl Möbius. Dahl remained in Berlin until he retired, and his type collection is held in that museum. Although he described in many animal groups, Dahl concentrated on spider ...

Orb-weaver Spider
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs. The family has a cosmopolitan distribution, including many well-known large or brightly colored garden spiders. With 3,108 species in 186 genera worldwide, the Araneidae comprise the third-largest family of spiders (behind the Salticidae and Linyphiidae). Araneid webs are constructed in a stereotypical fashion, where a framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets. Orb webs are also produced by members of other spider families. The long-jawed orb weavers (Tetragnathidae) were formerly included in the Araneidae; they are closely related, being part of the superfamily Arane ...

Gasteracantha
''Gasteracantha'' is a genus of orb-weaver spiders first named by Carl Jakob Sundevall in 1833. Species of the genus are known as spiny-backed orb-weavers, spiny orb-weavers, or spiny spiders. The females of most species are brightly colored with six prominent spines on their broad, hardened, shell-like abdomens. The name ''Gasteracantha'' is derived from the Greek (), meaning "belly, abdomen", and (), meaning "thorn, spine". Spiny-backed orb-weavers are sometimes colloquially called "crab spiders" because of their shape, but they are not closely related to the true crab spiders. Other colloquial names for certain species include thorn spider, star spider, kite spider, or jewel spider. Members of the genus exhibit strong sexual dimorphism. Females are several times larger than males, which lack prominent spines or bright colors. ''Gasteracantha'' species are distributed worldwide in tropical and subtropical climates. The genus is most diverse in tropical Asia, from India t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Sundas
The Lesser Sunda Islands or nowadays known as Nusa Tenggara Islands ( id, Kepulauan Nusa Tenggara, formerly ) are an archipelago in Maritime Southeast Asia, north of Australia. Together with the Greater Sunda Islands to the west they make up the Sunda Islands. The islands are part of a volcanic arc, the Sunda Arc, formed by subduction along the Sunda Trench in the Java Sea. A bit more than 20 million people live on the islands. Etymologically, Nusa Tenggara means "Southeast Islands" from the words of ''nusa'' which means 'island' from Old Javanese language and ''tenggara'' means 'southeast'. The main Lesser Sunda Islands are, from west to east: Bali, Lombok, Sumbawa, Flores, Sumba, Savu, Rote, Timor, Atauro, Alor archipelago, Barat Daya Islands, and Tanimbar Islands.

Sulawesi
Sulawesi (), also known as Celebes (), is an island in Indonesia. One of the four Greater Sunda Islands, and the world's eleventh-largest island, it is situated east of Borneo, west of the Maluku Islands, and south of Mindanao and the Sulu Archipelago. Within Indonesia, only Sumatra, Borneo, and New Guinea, Papua are larger in territory, and only Java and Sumatra have larger populations. The landmass of Sulawesi includes four peninsulas: the northern Minahassa Peninsula, Minahasa Peninsula, the East Peninsula, Sulawesi, East Peninsula, the South Peninsula, Sulawesi, South Peninsula, and the Southeast Peninsula, Sulawesi, Southeast Peninsula. Three gulfs separate these peninsulas: the Gulf of Tomini between the northern Minahasa and East peninsulas, the Tolo Gulf between the East and Southeast peninsulas, and the Bone Gulf between the South and Southeast peninsulas. The Strait of Makassar runs along the western side of the island and separates the island from Borneo. Etymology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lombok
Lombok is an island in West Nusa Tenggara province, Indonesia. It forms part of the chain of the Lesser Sunda Islands, with the Lombok Strait separating it from Bali to the west and the Alas Strait between it and Sumbawa to the east. It is roughly circular, with a "tail" ( Sekotong Peninsula) to the southwest, about across and a total area of about including smaller offshore islands. The provincial capital and largest city on the island is Mataram. Orang Lombok is some what similar in size and density, and shares some cultural heritage with the neighboring island of Bali to the west. However, it is administratively part of West Nusa Tenggara, along with the larger and more sparsely populated island of Sumbawa to the east. Lombok is surrounded by a number of smaller islands locally called Gili. The island was home to some 3,168,692 Indonesians as recorded in the decennial 2010 censusBiro Pusat Statistik, Jakarta, 2011. and 3,758,631 in the 2020 Census;Badan Pusat Statistik, ...

Spiders Described In 1914
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 separate th ...
