Marmyan
''Marmyan'' is an extinct genus of scale insect, containing a single species, ''Marmyan barbarae'' and unplaced in any coccid family. The genus is solely known from the Albian – Cenomanian Burmese amber deposits. History and classification ''Marmyan'' is known from the holotype specimen, collection number BMNH In. 20160(1), which along several other insects of different orders, are inclusions in a transparent chunk of Burmese amber. As of 2004, the type insect was part of the amber collections housed at the British Museum of Natural History, London, England. The amber specimen was recovered from deposits exposed in the Hukawng Valley of Kachin State, Myanmar. Burmese amber has been radiometrically dated using U- Pb isotopes, yielding an age of approximately 99 million years, close to the Aptian – Cenomanian boundary. The holotype was first studied by paleoentomologist and coccid researcher Jan Koteja, of the Agricultural University of Kraków. Kotejas's ...

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. The Albia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aptian
The Aptian is an age in the geologic timescale or a stage in the stratigraphic column. It is a subdivision of the Early or Lower Cretaceous Epoch or Series and encompasses the time from 121.4 ± 1.0 Ma to 113.0 ± 1.0 Ma (million years ago), approximately. The Aptian succeeds the Barremian and precedes the Albian, all part of the Lower/Early Cretaceous. The Aptian partly overlaps the upper part of the Western European Urgonian Stage. The Selli Event, also known as OAE1a, was one of two oceanic anoxic events in the Cretaceous Period, which occurred around 120 Ma and lasted approximately 1 to 1.3 million years. The Aptian extinction was a minor extinction event hypothesized to have occurred around 116 to 117 Ma.Archangelsky, Sergio.The Ticó Flora (Patagonia) and the Aptian Extinction Event" ''Acta Paleobotanica'' 41(2), 2001, pp. 115-22. Stratigraphic definitions The Aptian was named after the small city of Apt in the Provence region of France, which is also known for its cry ...

Grimaldiella
''Funchalia'' is a genus of deep-water prawns of the family Penaeidae. Six species are currently recognised: *'' Funchalia danae'' Burkenroad, 1940 *'' Funchalia meridionalis'' (Lenz & Strunck, 1914) *'' Funchalia sagamiensis'' Fujino, 1975 *'' Funchalia taaningi'' Burkenroad, 1940 *'' Funchalia villosa'' (Bouvier, 1905) *'' Funchalia woodwardi'' Johnson, 1868 Few specimens of ''Funchalia'' are present in museum collections, mostly due to the lack of sampling at the great depths where it lives. It probably has a cosmopolitan distribution. The genus was erected in 1868, when James Yate Johnson James Yate Johnson (1820, in Kendal, Westmorland – 2 February 1900, in Funchal) was an English naturalist. Johnson lived in Madeira from around 1851, studied marine fish, crustacea, sea anemones and sponges and terrestrial spiders, flowering pl ... erected it for the species '' Funchalia woodwardi'', which he had collected off Madeira; the specific epithet commemorated Henry Woodw ...

Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Eriococcidae
Eriococcidae is a family of scale insects in the order Hemiptera. They are commonly known as felt scales or eriococcids. Each species is usually specific to a different plant host, or closely related group of hosts. Recent research using ribosomal DNA has shown that the family Eriococcidae is not a single monophyletic group but is an aggregation of several different groups. Some species that appear morphologically similar seem to be only distantly related while dissimilar species are sometimes more closely related.Cook, L.G. & Gullan, P.J. 2004: The gall-inducing habit has evolved multiple times among the eriococcid scale insects (Sternorrhyncha: Coccoidea: Eriococcidae). ''Biological Journal of the Linnean Society'', 83: 441-452. DOI: 10.1111/j 1095-8312.2004.00396.x The type genus '' Eriococcus'' has been shown to be polyphyletic. Morphology Felt scales are a diverse group of scale insects. They produce a white, yellowish or gray membranous capsule or ovisac that encloses the p ...

Pseudococcidae
Mealybugs are insects in the family Pseudococcidae, unarmored scale insects found in moist, warm habitats. Many species are considered pests as they feed on plant juices of greenhouse plants, house plants and subtropical trees and also act as a vector for several plant diseases. Some ants live in symbiotic relationships with them, protecting them from predators and feeding off the honeydew which they excrete. Description Mealybugs are sexually dimorphic: females appear as nymphs, exhibiting reduced morphology, and lack wings, although unlike many female scale insects, they often retain legs and can move. Males are smaller, gnat-like and have wings. Since mealybugs (as well as all other Hemiptera) are hemimetabolous insects, they do not undergo complete metamorphosis in the true sense of the word. However, male mealybugs do exhibit a radical change during their life cycle, changing from wingless, ovoid nymphs to wasp-like flying adults. Mealybug females feed on plant sap, nor ...

Putoidae
Putoidae is a family of scale insects commonly known as giant mealybugs or putoids. There is probably a single genus, ''Puto'', containing about sixty species. The genus name ''Macrocerococcus'' has also been used but it is now considered to be a synonym of ''Puto''. The genus ''Puto'' was formerly classified as a member of the Pseudococcidae; however, it so significantly differed from the rest of the Pseudococcidae that it was accorded its own family Putoidae. Hosts Giant mealybugs occur on a wide range of hosts, each species having its own specific host. Host plants commonly include conifers, grasses and various woody shrubs. All parts of the plant can be infested. Description The adult female is oval and up to five millimetres long and concealed by tufts of powdery white wax. If the wax is removed, two longitudinal black stripes can be seen on the upper surface of the body and the wax glands are large and conspicuous. The legs and antennae are well developed and a dark colour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...
