Arulenus
''Arulenus'' is a genus of pygmy grasshopper. , it consists of two species: * '' Arulenus miae'' * '' Arulenus validispinus'' Both species are endemic to Mindanao in the Philippines. Description Characteristic features of this genus include: the lack of tegmina and of alae, a smooth pronotum with large, slightly wrinkled spines on its discus, and outwardly turned lateral paranotal lobes. Taxonomic history Carl Stål circumscribed ''Arulenus'' in 1877 for the species ''A. validispinus'' and ''A. punctatus'', which Stål described in the same paper. In 1887, Ignacio Bolívar Ignacio Bolívar y Urrutia (9 November 1850, Madrid – 19 November 1944, Mexico City) was a Spanish naturalist and entomologist, and one of the founding fathers of Spanish entomology.

Arulenus Miae
''Arulenus miae'' is a species of pygmy grasshopper which is found on the island Mindanao in the Philippines. It was described in 2016 by Josip Skejo and Joy Honezza S. Caballero. They became aware of the species' existence through a photograph posted to a Facebook group. Specimens were later collected from Bukidnon Province. It is named in honor of a friend of Skejo, named Mia. Skejo and Caballero were praised for going through the process of collecting specimens instead of writing their description and naming a new taxon only based on a photograph.

Pygmy Grasshopper
Tetrigidae is an ancient family in the order Orthoptera, which also includes similar families such as crickets, grasshoppers, and their allies. Species within the Tetrigidae are variously called groundhoppers, pygmy grasshoppers,Borror DJ, Tripplehorn CA, Johnson NF (1989) An Introduction to the Study of Insects, 6th edition. Harcourt Brace College Publishers. New York. pg 213 pygmy devils or (mostly historical) "grouse locusts".Imms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp. Diagnostic characteristics Tetrigidae are typically less than 20 mm in length and are recognizable by a long pronotum. This pronotum extends over the length of the abdomen, sometimes to the tip of the wings, and ends in a point. In other Orthoptera, the pronotum is short and covers neither the abdomen nor the wings. Tetrigidae are generally cryptic in coloration. Some species have enlarged pronota that mimic leaves, stones or twigs. Other charac ...

Carl Stål
Carl Stål (21 March 1833 – 13 June 1878) was a Swedish entomologist specialising in Hemiptera. He was born at Karlberg Castle, Stockholm on 21 March 1833 and died at Frösundavik near Stockholm on 13 June 1878. He was the son of architect, author and officer Carl Stål then Colonel, Swedish Corps of Engineers. He matriculated at Uppsala University in 1853, studying medicine and passing the medico-philosophical examination in 1857. He then turned to entomology and completed his Ph.D. at the University of Jena in 1859. The same year he became assistant to Carl Henrik Boheman in the Zoological department of the Swedish Museum of Natural History in Stockholm, where, in 1867, he was appointed keeper with the title of professor. He made collecting trips in Sweden and throughout Europe and visited other museums including the collection of Johan Christian Fabricius in Kiel. His study of the Fabrician types resulted in his "Hemiptera Fabriciana". A significant part of Stål's work wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caelifera Genera
The Caelifera are a suborder of orthopteran insects. They include the grasshoppers and grasshopper-like insects, as well as other superfamilies classified with them: the ground-hoppers (Tetrigoidea) and pygmy mole crickets (Tridactyloidea). The latter should not be confused with the mole crickets (Gryllotalpidae), which belong to the other Orthopteran sub-order Ensifera. The name of this suborder comes from Latin meaning ''chisel-bearing'' ("chisel" in Latin: ''caelum''), referring to the "stout" shape of its species' ovipositors. Subdivisions and their distribution The Caelifera include some 2,400 valid genera and about 12,000 known species. Many undescribed species probably exist, especially in tropical forests. The Caelifera have a predominantly tropical distribution (as with most Orthoptera) with fewer species known from temperate climate zones. Caelifera are divided into two infraorders: the more basal Tridactylidea and the Acrididea or grasshopper-like species. Thi ...

Taxa Named By Carl Stål
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monospecific
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.'' ...

Pronotum
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also *Glossary of entomolo ...

Ignacio Bolívar
Ignacio Bolívar y Urrutia (9 November 1850, Madrid – 19 November 1944, Mexico City) was a Spanish naturalist and entomologist, and one of the founding fathers of Spanish entomology. He helped found the ''Real Sociedad Española de Historia Natural'' (Royal Spanish Natural History Society) in 1871, and was the author of several books and of over 1000 species. He also encouraged other naturalists to study entomology, José María de la Fuente being one example. In this field he wrote more than 300 books and monographs and described more than thousand new species and about 200 genera. After the Spanish Civil War he was exiled to Mexico Mexico (Spanish: México), officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatema ... when the nationalist government harshly repressed Republican militants and sympathisers. ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...
