Rotoitidae
The Rotoitidae are a very small family of rare, relictual parasitic wasps in the superfamily Chalcidoidea, known primarily from fossils (14 extinct species in two genera, '' Baeomorpha'' and '' Taimyromorpha'').Huber JT, Shih C, Dong R (2019) A new species of ''Baeomorpha'' (Hymenoptera, Rotoitidae) from mid-Cretaceous Burmese amber. Journal of Hymenoptera Research 72: 1-10. https://doi.org/10.3897/jhr.72.35502 Only two extant species are known, each in its own genus, one from New Zealand and one from Chile, and little is known about their biology. Females of the Chilean species, '' Chiloe micropteron'', have their wings reduced to tiny bristles. Most fossil species are known from the Late Cretaceous (Santonian) Taimyr amber of Russia and Late Cretaceous (Campanian) Canadian amber, but one species, ''Baeomorpha liorum'' is known from the mid Creaceous (late Albian-earliest Cenomanian) Burmese amber.

Baeomorpha
''Baeomorpha'' is an extinct genus of rotoitid parasitic wasp, known from the Late Cretaceous (~99-72 ma) of Laurasia. The type species, ''B. dubitata'' was named by Charles Thomas Brues for a specimen found in 72 million year old Canadian Amber.C. T. Brues. 1937. Superfamilies Ichneumonoidea, Serphoidea, and Chalcidoidea, in Insects and arachnids from Canadian amber. ''University of Toronto Studies in Geology'' 40:27-44 The vast majority of species are known from the Russian Taimyr amber, of upper Santonian age but two species (including type) are known from the upper Campanian Canadian amber, while one species is known from the lower Cenomanian Burmese amber.

Chiloe Micropteron
''Chiloe micropteron'' is a species of wasp of the family Rotoitidae. The species was described by Gibson and Huber in 2000 from specimens collected in Chile. The generic name is derived from Chiloé Island Chiloé Island ( es, Isla de Chiloé, , ) also known as Greater Island of Chiloé (''Isla Grande de Chiloé''), is the largest island of the Chiloé Archipelago off the west coast of Chile, in the Pacific Ocean.

Burmese Amber
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its alleged role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected. Geological context, depositional environment and age The amber is found within the Hukawng Basin, a large Cretaceous-Cenozoic sedimentary basin within northern Myanmar. The s ...

Chalcidoidea
Chalcid wasps (, , for their metallic colour) are insects within the superfamily Chalcidoidea, part of the order Hymenoptera. The superfamily contains some 22,500 known species, and an estimated total diversity of more than 500,000 species, meaning the vast majority have yet to be discovered and described. The name "chalcid" is often confused with the name "chalcidid", though the latter refers strictly to one constituent family, the Chalcididae, rather than the superfamily as a whole; accordingly, most recent publications (e.g.,) use the name "chalcidoid" when referring to members of the superfamily. Most chalcid wasps are parasitoids of other insects, though other life styles are known, with the herbivorous fig wasps acting as pollinators. Various species are used as biological pest control agents or in scientific research. Description Chalcidoids are generally small wasps, averaging 1.5 mm in length and usually being less than 3 mm. The body is often metallic in colour. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Noyes (entomologist)
John Stuart Noyes (born Cardiff 1949) is a Welsh entomologist. At the age of 14 an article entitled "My Hobby has Wings" about Noyes appeared in his local newspaper, the ''Pontypridd Observer''; this 1963 article highlighted Noyes' interest in entomology at an early age. In 1967 he began studying for a degree in zoology and applied entomology at Imperial College, London where he completed his doctoral thesis on the biology of the leek moth (''Acrolepiopsis assectella''). In 1974 he was appointed as a researcher in the Chalcidoidea at the British Museum (Natural History). He was seconded to the Department of Scientific and Industrial Research in New Zealand where he conducted a survey of the Chalcidoidea of New Zealand in 1980 and 1981. He travelled widely in the course of his research into the Chalcidoidea and has published over 80 papers, with some major monographs, and described one new family, 88 new genera and 644 new species of Chalcidoidea. When he retired he was reviewing t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campanian
The Campanian is the fifth of six ages of the Late Cretaceous Epoch on the geologic timescale of the International Commission on Stratigraphy (ICS). In chronostratigraphy, it is the fifth of six stages in the Upper Cretaceous Series. Campanian spans the time from 83.6 (± 0.2) to 72.1 (± 0.2) million years ago. It is preceded by the Santonian and it is followed by the Maastrichtian. The Campanian was an age when a worldwide sea level rise covered many coastal areas. The morphology of some of these areas has been preserved: it is an unconformity beneath a cover of marine sedimentary rocks. Etymology The Campanian was introduced in scientific literature by Henri Coquand in 1857. It is named after the French village of Champagne in the department of Charente-Maritime. The original type locality was a series of outcrop near the village of Aubeterre-sur-Dronne in the same region. Definition The base of the Campanian Stage is defined as a place in the stratigraphic column wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of Chile
The wildlife of Chile encompasses a diverse range of animals, a condition is attributed to the country's slender and elongated shape, which spans a wide range of latitude, and also its altitude, ranging from the windswept coastline of the Pacific coast on the west to northern Andes to the sub-Antarctic, high Andes mountains in the east. There are many distinct ecosystems. Chile, often called "The spine of South America", has 100 protected areas covering a total area of 14.5 million hectares (20% of the country) in 36 National parks, 49 National Reserves, and 15 National Monuments. In the southern part of Chile, 50 percent of the flora (part of temperate rain forest called the Valdivian forests) is endemic which is a unique feature in the world. '' Lapageria rosea'' (Chilean bellflower) is the national flower, Andean condor, (''Vultur gryphus'') (NT), is the national bird, and South Andean huemul (''Hippocamelus bisulcus''), is the national animal of Chile. Legally, wildlife in Chil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mymaridae
The Mymaridae, commonly known as fairyflies or fairy wasps, are a family (biology), family of chalcid wasp, chalcidoid wasps found in temperate and tropical regions throughout the world. The family contains around 100 genera with 1400 species. Fairyflies are very tiny insects, like most chalcidoid wasps, mostly ranging from long. They include the Dicopomorpha echmepterygis, world's smallest known insect, with a body length of only , and the Kikiki, smallest known flying insect, only long. They usually have nonmetallic black, brown, or yellow bodies. The antennae of the females are distinctively tipped by club-like segments, while male antennae are thread-like. Their wings are usually slender and possess long bristles, giving them a hairy or feathery appearance, although some species may have greatly reduced stubby wings or lack wings altogether. They can be distinguished from other chalcidoids by the H-shaped pattern of sutures on the front of their heads. Fairyflies are among ...

Cenomanian
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for marine spec ...

Albian
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column.
