Pachycondyla Parvula
''Pachycondyla parvula'' is an extinct species of ant in the formicid subfamily Ponerinae described by from a fossil found in Europe. ''P. parvula'' is one of six Lutetian ''Pachycondyla'' species. History and classification When described ''Pachycondyla parvula'' was known from six fossil insects which are compression-impression fossils preserved in layers of soft sedimentary rock. Along with other well preserved insect fossils, the ''P. parvula'' specimens were collected from layers of Lutetian Messel Formation rock in the Messel pit World Heritage Site. The Messel formation is composed of brown coals, oil shales, and bituminous shale, which preserved numerous insects, fish, birds, reptiles, and terrestrial mammals as a notable lagerstätten. The area is a preserved maar lake which initially formed approximately 47 million years ago as the result of volcanic explosions. At the time of description, the holotype specimen, number SMF MeI 10638, along with the paratype an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutetian
The Lutetian is, in the geologic timescale, a stage (stratigraphy), stage or age (geology), age in the Eocene. It spans the time between . The Lutetian is preceded by the Ypresian and is followed by the Bartonian. Together with the Bartonian it is sometimes referred to as the Middle Eocene Subepoch. Stratigraphic definition The Lutetian was named after Lutetia, the Latin language, Latin name for the city of Paris. The Lutetian Stage was introduced in scientific literature by French geologist Albert de Lapparent in 1883 and revised by A. Blondeau in 1981. The base of the Lutetian Stage is at the first appearance of the nanofossil ''Blackites inflatus'', according to an official reference profile (GSSP) established in 2011. Of two candidates located in Spain, the Gorrondatxe section was chosen.See thwebsite of Eustoquio Molinafor these candidates. The top of the Lutetian (the base of the Bartonian) is at the first appearance of calcareous nannofossils, calcareous nanoplankton s ...

Naturmuseum Senckenberg
The Naturmuseum Senckenberg () is a museum of natural history, located in Frankfurt am Main. It is the second-largest of its kind in Germany. In 2010, almost 517,000 people visited the museum, which is owned by the Senckenberg Nature Research Society. Senckenberg's slogan is "world of biodiversity". , the museum exhibits 18 reconstructed dinosaurs. History In 1763, Johann Christian Senckenberg donated 95,000 guilders–his entire fortune–to establish a community hospital and promote scientific projects. Senckenberg died in 1772. In 1817, 32 Frankfurt citizens founded the non-profit Senckenberg Nature Research Society, (SGN), which is a member of the Leibniz Association. Soon after, donated his collection of bird and mammal specimens to the society. The Naturmuseum Senckenberg was founded in 1821, just four years later. Initially located near the Eschenheimer Turm, the museum moved to a new building on Senckenberganlage in 1907. In 1896 a mummified Egyptian child in thei ...

Mandible (insect Mouthpart)
Insect mandibles are a pair of appendages near the insect's mouth, and the most anterior of the three pairs of oral appendages (the labrum is more anterior, but is a single fused structure). Their function is typically to grasp, crush, or cut the insect's food, or to defend against predators or rivals. Insect mandibles, which appear to be evolutionarily derived from legs, move in the horizontal plane unlike those of vertebrates, which appear to be derived from gill arches and move vertically. Grasshoppers, crickets, and other simple insects The mouthparts of orthopteran insects are often used as a basic example of mandibulate (chewing) mouthparts, and the mandibles themselves are likewise generalized in structure. They are large and hardened, shaped like pinchers, with cutting surfaces on the distal portion and chewing or grinding surfaces basally. They are usually lined with teeth and move sideways. Large pieces of leaves can therefore be cut and then pulverized near the mout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antenna (biology)
An antenna (plural: antennae) is one of a pair of appendages used for Sensory system, sensing in arthropods. Antennae are sometimes referred to as ''feelers''. Antennae are connected to the first one or two Segmentation (biology), segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing tactition, touch, air motion, heat, vibration (sound), and especially insect olfaction, smell or gustation, taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate (biology), substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members i ... [...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. Wasps, bees and ants In hymenopterans of the suborder Apocrita (wasps, bees and ants), the mesosoma 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. Encyrtidae head thorax abdomen.jpg, The mesosoma (thorax plus propodeum) and metasoma (remaining segments of the abdomen) of an encyrtid wasp. Scheme ant worker anatomy-en.svg, In the worker ant the mesosoma includes the pronotum, mesonotum, scutellum and the propodeum. The petiole and the gaster comprise the metasoma.

Gyne
The gyne (, from Greek γυνή, "woman") is the primary reproductive female caste of social insects (especially ants, wasps, and bees of order Hymenoptera, as well as termites). Gynes are those destined to become queens, whereas female workers are typically barren and cannot become queens. Having a queen is what makes a "queenright" hive, nest, or colony of eusocial insects. A colony with multiple queens is said to be a polygyne form, whereas one with only one is a monogyne form. The ancient Greek origin of ''gyne'' meant a woman who had given birth to at least one child. In species lacking morphological castes (i.e., where "workers" may not be sterile), the term "gyne" is usually reserved for those females whose entire life is spent as a reproductive or potential reproductive, as opposed to those who start life as a worker and subsequently attain reproductive status (often called a "replacement queen" or a "laying worker"). These can be seen in certain species of stingless be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest.
