Andrena Antoinei
''Andrena antoinei'' is an extinct species of mining bee in the family Andrenidae described from a single fossil found in a Late Oligocene lake in present-day France that existed in semi-arid conditions. History and classification ''A. antoinei'' was described from a solitary fossil, which is a compression-impression fossil pair preserved in layers of soft sedimentary rock. Along with other well preserved insect fossils, the ''A. antoinei'' specimen was collected from layers of Late Oligocene lacustrine rock belonging to the "calcaire de Campagne Calavon" sediments. The material is exposed along the northern slopes of the Luberon mountains near Céreste in southern France. The sediments are reported as from a shallow paleolake that was formerly considered about 30 million year old and Rupelian in age. Recent restudy of formation has suggested the older Late Oligocene age. The paleoflora preserved in the shales suggest the lake was surrounded by a mixed-mesophytic forest, tho ...

Late Oligocene
The Chattian is, in the geologic timescale, the younger of two ages or upper of two stages of the Oligocene Epoch/Series. It spans the time between . The Chattian is preceded by the Rupelian and is followed by the Aquitanian (the lowest stage of the Miocene). Stratigraphic definition The Chattian was introduced by Austrian palaeontologist Theodor Fuchs in 1894. Fuchs named the stage after the Chatti, a Germanic tribe.Berry, Edward W"The Mayence Basin, a Chapter of Geologic History" ''The Scientific Monthly'', Vol. 16, No. 2, February 1923. pp. 114. Retrieved March 18, 2020. The original type locality was near the German city of Kassel. The base of the Chattian is at the extinction of the foram genus ''Chiloguembelina'' (which is also the base of foram biozone P21b). An official GSSP for the Chattian Stage was ratified in October of 2016. The top of the Chattian Stage (which is the base of the Aquitanian Stage, Miocene Series and Neogene System) is at the first appearance of ...

Metasoma
The metasoma is the posterior part of the body, or tagma, of arthropods whose body is composed of three parts, the other two being the prosoma and the mesosoma. In insects, it contains most of the digestive tract, respiratory system, and circulatory system, and the apical segments are typically modified to form genitalia. In a few of the most primitive insects (the Archaeognatha), the metasomal segments bear small, articulated appendages called "styli", which are often considered to be vestigial. There are also pre-apical appendages in most insect orders, called cerci, which may be multi-segmented and almost resembling a posterior pair of antennae; these may be variously modified, or lost entirely. Otherwise, most adult insects lack appendages on the metasoma, though many larval insects (e.g., caterpillars) have some form of appendages, such as prolegs or, in aquatic insects, gills. In apocritan Hymenoptera (wasps, bees and ants), the metasoma consists of the second abdominal ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mesosoma
The mesosoma is the middle part of the body, or tagma, of arthropods whose body is composed of three parts, the other two being the prosoma and the metasoma. It bears the legs, and, in the case of winged insects, the wings. In hymenopterans of the suborder Apocrita (wasps, bees and ants), it consists of the three thoracic segments and the first abdominal segment (the propodeum). For historical reasons, in ants it is commonly referred to by the alternative name alitrunk. In scorpions, it is composed of six segments and forms the first part of the abdomen, containing all of the major organs. The first segment contains the sexual organs as well as a pair of vestigial and modified appendages forming a structure called the genital operculum. The second segment bears a pair of featherlike sensory organs known as the pectines; the final four segments each contain a pair of book lungs. The mesosoma is armoured with chitinous plates, on the upper surface by the tergites and on the low ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Euglossopteryx Biesmeijeri
''Euglossopteryx'' is an extinct genus of bee in the family Apidae known from a fossil found in North America. There is one described species in the genus, ''Euglossopteryx biesmeijeri''. History and classification ''Euglossopteryx biesmeijeri'' was described from a solitary fossil, which is a compression-impression fossil preserved in layers of soft sedimentary rock. Along with other well preserved insect fossils, the ''E. biesmeijeri'' specimen was collected from layers of the Middle Eocene Parachute Creek Member of the Green River Formation. The formation is a group of Late Paleocene to Late Eocene depositional basins in Wyoming and Utah. The Parachute Creek Member is a composed of oil shales from a shallow mountain lake that existed for around 20 million years. Study of the paleoflora preserved in the shales indicates the lake was around in elevation surrounded by a tropical to subtropical environment that had a distinct dry season. At the time of study, the holotype was ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bombus Cerdanyensis
''Bombus cerdanyensis'' is an extinct species of bumble bee in the family Apidae known from a fossil found in Europe. History and classification ''Bombus cerdanyensis'' was described from a solitary fossil, which is a compression-impression fossil pair preserved in layers of soft sedimentary rock. Along with other well preserved insect fossils, the ''B. cerdanyensis'' specimen was collected from layers of Late Miocene terrigenous and diatomites exposed around the small town of Bellver de Cerdanya, Spain. The sediments are reported as from a deep mountain paleolake that exists about 10 million years ago. Study of the paleoflora preserved in the shales indicates the lake was around in elevation in a climate that was warmer than the current conditions in the area. At the time of study, the holotype counterpart and part were part of the paleoentomology collections housed by the Museum National d’Histoire Naturelle. It was first studied by an international team of researchers ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Andrena
''Andrena'' is a genus of bees in the family Andrenidae. With over 1,500 species, it is one of the largest genera of animals. It is a strongly monophyletic group that is difficult to split into more manageable divisions; currently, ''Andrena'' is organized into 104 subgenera. It is nearly worldwide in distribution, with the notable exceptions of Oceania and South America. Bees in this genus are commonly known as mining bees due to their ground-nesting lifestyle. Morphology ''Andrena'' are generally medium-sized bees; body length ranges between 8 and 17 mm with males being smaller and more slender than females. Most are black with white to tan hair, and their wings have either two or three submarginal cells. They carry pollen mainly on femoral scopal hairs, but many ''Andrena'' have an additional propodeal corbicula for carrying some pollen on their thorax. C. D. Michener (2007) ''The Bees of the World'', 2nd Edition, Johns Hopkins University Press. They can be distin ...

Andreninae
The bee subfamily Andreninae is a nearly cosmopolitan lineage, with most of its diversity in one genus, ''Andrena'', which contains over 1500 species. The remaining four genera in the subfamily only contain a total of 9 species. Females of three of the genera (''Ancylandrena'', ''Andrena'', and '' Megandrena'') have broad, velvety depressions called "facial foveae" on the face between the eyes and the antennae; in all other members of the family, the foveae are much smaller, typically reduced to grooves or pits at the upper margin of the eyes. ''Ancylandrena'' and ''Megandrena'' occur only in the desert regions of southwestern North America (Nevada, California, Arizona, Sonora, and Baja California), while ''Andrena'' is nearly worldwide. ''Euherbstia'' and '' Orphana'' are rare bees restricted to desert regions of Chile. Unlike the subfamily Panurginae, none of the species of Andreninae have yellow markings anywhere other than on the face; those markings, when present, are usually ...

Morphometric
Morphometrics (from Greek μορϕή ''morphe'', "shape, form", and -μετρία ''metria'', "measurement") or morphometry refers to the quantitative analysis of ''form'', a concept that encompasses size and shape. Morphometric analyses are commonly performed on organisms, and are useful in analyzing their fossil record, the impact of mutations on shape, developmental changes in form, covariances between ecological factors and shape, as well for estimating quantitative-genetic parameters of shape. Morphometrics can be used to quantify a trait of evolutionary significance, and by detecting changes in the shape, deduce something of their ontogeny, function or evolutionary relationships. A major objective of morphometrics is to statistically test hypotheses about the factors that affect shape. "Morphometrics", in the broader sense, is also used to precisely locate certain areas of organs such as the brain, and in describing the shapes of other things. Forms Three general appro ...

Melittology
Melittology (from Greek , ''melitta'', "bee"; and ''-logia'') is a branch of entomology concerning the scientific study of bees. It may also be called apicology. Melittology covers the species found in the clade Anthophila within the superfamily Apoidea, comprising more than 20,000 species, including bumblebees and honey bees. Subdivisions * Apiology – (from Latin , "bee"; and Ancient Greek , ''-logia'') is the scientific study of honey bees. Honey bees are often chosen as a study group to answer questions on the evolution of social systems. :* Apidology is a variant spelling of ''apiology'' used outside of the Western Hemisphere, primarily in Europe; it is sometimes used interchangeably with ''melittology''. Melittological societies Melittologists and apiologists are served by a number of scientific societies, both national and international in scope. Their main role is to encourage the study of bees and apicultural research. * ''International Bee Research Association'' * ...

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 ...
