Termopsidae
Termopsidae is an extinct family of termites in the order Blattodea. The five extant genera formerly included in Termopsidae ('' Archotermopsis'', '' Hodotermopsis'', '' Porotermes'', '' Stolotermes'', and ''Zootermopsis'') have recently been treated as part of the newer family Archotermopsidae, leaving only extinct taxa in Termopsidae. Several prehistoric genera are placed herein, known only from fossils. Since only a small part of the erstwhile diversity of dampwood termites survives, it is rather difficult to assign these to subfamilies. Several seem to represent very ancient members of the family; they may be quite basal Termopsidae, so it is indeed unwarranted to place them into a subfamily at all. * Genus '' Asiatermes'' (Early Cretaceous of China) * Genus '' Huaxiatermes'' (Early Cretaceous of China) * Genus '' Mesotermopsis'' (Early Cretaceous of China) * Genus '' Cretatermes'' (Late Cretaceous of Labrador, Canada) * Genus '' Lutetiatermes'' (Late Cretaceous of France) * ...

Termites
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees an ...

Archotermopsidae
Archotermopsidae is a family of termites in the order Blattodea, known as dampwood termites, formerly included within the family Termopsidae. They constitute a small and rather primitive family with five extant genera and 13–20 living species. They may be a nuisance, but compared to the drywood termites (Kalotermitidae), usually do not cause extensive damage to buildings or other man-made structures. As their name implies, they eat wood that is not dried out, perhaps even rotting, and consequently of little use to humans. Taxonomy In 2009, the five extant genera from the family Termopsidae ('' Archotermopsis'', '' Hodotermopsis'', '' Porotermes'', '' Stolotermes'', and ''Zootermopsis'') were moved to a newly created family, Archotermopsidae (''Zootermopsis'' had previously been treated as part of the family Hodotermitidae), so that the family Termopsidae now includes only fossil taxa: ''Asiatermes'', ''Huaxiatermes'', and ''Mesotermopsis'' (Early Cretaceous of China); ''Cretate ...

Zootermopsis
''Zootermopsis'' is a genus of termites in the Dampwood termite family (Archotermopsidae Archotermopsidae is a family of termites in the order Blattodea, known as dampwood termites, formerly included within the family Termopsidae. They constitute a small and rather primitive family with five extant genera and 13–20 living species ...). They are mostly found in western North America, ranging from Canada to Mexico, with the exception of '' Z. nevadensis'', which has become established in Japan. They live in rotting wood, commonly inhabiting fallen or dead trees in North America's temperate rain forests, where they break down the wood's cellulose with the help of symbiotic protozoa and bacteria in their stomachs. The life and reproductive cycles of these termites are relatively normal compared to other members of its family. Species can be identified using the shape and position of the subsidiary tooth in all non-soldier castes, allowing a more certain identification than the ...

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nils Holmgren
Nils Frithiof Holmgren (1877–1954) was a Swedish zoologist and comparative anatomist. He was professor of zoology at Stockholm University from 1921 to 1944. In 1906 Holmgren defended his doctoral dissertation at Stockholm University. In 1912 he became a teacher there, and in 1919 assistant professor of zoology, and in 1921 full professor. His early work focussed on the biology, systematics and anatomy of insects, especially termites, as in (1906) and (1909–1912). In later work he focused on the structure of the brain in worms, arthropods and vertebrates, publishing (1916) (Comparative anatomy of the brain), (1919), (1920), ''Points of view concerning forebrain morphology in lower vertebrates'' (1922), (with C. J. van der Horst) ''Contribution to the morphology of the brain'' in Ceratodus (1925), and ''Points of view concerning forebrain morphology in higher vertebrates'' (1925). This work made him a world expert on the nervous systems of the lower vertebrates. Later w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
