Opisthoncana
''Opisthoncana'' is a monotypic genus of jumping spiders containing the single species, ''Opisthoncana formidabilis''. It was first described by Embrik Strand in 1913, and is only found on New Ireland. The name is a variation of the salticid genus ''Opisthoncus ''Opisthoncus'' is a genus of Oceania, South Pacific Salticidae, jumping spiders that was first described by Ludwig Carl Christian Koch in 1880.

Embrik Strand
Embrik Strand (2 June 1876 – 3 November 1947) was an entomologist and arachnologist who classified many insect and spider species including the greenbottle blue tarantula. Life and career Strand was born in Ål, Norway. He studied at the University of Kristiania (now University of Oslo). Around 1900 he focused on collecting insect specimens from Norway. These are now deposited at the university's museum, where he worked as a curator from 1901 to 1903. After studying at the University of Oslo Strand traveled in Norway from 1898 to 1903 collecting a great number of insects. For part of this time (1901–1903) he was a conservator in the museum of zoology of the university. He then left for Germany where he continued his studies of zoology at the University of Marburg (1903), then he worked with State Museum of Natural History Stuttgart (1905) and, later, that of Tübingen and then with Senckenberg Museum in Frankfurt. From 1907, he worked with Natural History Museum, Ber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

New Ireland (island)
New Ireland (Tok Pisin: ''Niu Ailan'') or Latangai, is a large island in Papua New Guinea, approximately in area with 120,000 people. It is named after the island of Ireland. It is the largest island of New Ireland Province, lying northeast of the island of New Britain. Both islands are part of the Bismarck Archipelago, named after Otto von Bismarck, and they are separated by Saint George's Channel. The administrative centre of the island and of New Ireland province is the town of Kavieng located at the northern end of the island. While the island was part of German New Guinea, it was named Neumecklenburg ("New Mecklenburg"). Geography The island is part of the Bismarck Archipelago and is often described as having the shape of a musket. New Ireland is surrounded by the Bismarck Sea in the southwest and by the Pacific Ocean in the northeast. For much of its in length, the island's width varies between less than to , yet the central mountainous spine is very steep an ...

Opisthoncus
''Opisthoncus'' is a genus of Oceania, South Pacific Salticidae, jumping spiders that was first described by Ludwig Carl Christian Koch in 1880. There are still many Australian species that have not yet been described. Species it contains thirty-two species, found only in Papua New Guinea and Australia: *''Opisthoncus abnormis'' L. Koch, 1881 – Australia (Queensland, New South Wales) *''Opisthoncus albiventris'' L. Koch, 1881 – Australia (New South Wales) *''Opisthoncus alborufescens'' L.

Spiders Of Oceania
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 se ...
