Syntelia Sinica
''Syntelia'' is a genus of beetles. It is the only genus in the family Synteliidae. There are seven known species, which are native to high-elevation regions in southern North America from central Mexico to Guatemala, and in eastern Asia, from India to Japan and eastern Russia. They are generally associated with rotting logs, typically found under bark, thought the Mexican species ''S. westwoodi'' has been found inside large decaying columnar cacti. Adults and larvae are predatory, feeding on insect larvae.Newton, Alfred F.. "Synteliidae Lewis, 1882: Coleoptera, Beetles". ''Handbook of Zoology Online'', edited by Andreas Schmidt-Rhaesa. Berlin, Boston: De Gruyter, 2016. A fossil species, ''Syntelia sunwukong'', is known from the Late Cretaceous (Cenomanian) aged Burmese amber of Myanmar. Adults are around in length. The characteristics of the family and genus include geniculate antennae with 3-segmented club, elongate body, narrowly separated coxae and tarsi with bisetose em ...

George Lewis (coleopterist)
George Lewis (1839–1926), F.L.S., F.E.S., was an English entomologist. He was a specialist in Coleoptera. Lewis was born on 5 August 1839, the second son of the Rev. R. Cr. Lewis, first Vicar of St. John's, Blackheath, S.E. He was educated at the Blackheath Proprietary School. In 1862 he went to China for the tea trade and returned to England twenty years later, after also spending periods in Japan and Sri Lanka. He married Miss Julia Hunter, of Iiiuer Park Road, Wimbledon Common. Soon after his marriage in 1867, he spent several years traveling and collecting beetles in Japan, and he visited that country again in 1880. He also collected in Ceylon and Algiers. An ardent entomologist from boyhood, Lewis made important collections of beetles in the East, most of which were acquired by the British Museum. He authored numerous taxa, including 750 species in the family Histeridae (a tiny fraction being listehere and had been for many years the recognized authority on the beetles o ...

Ceroid Cactus
The term ceroid cactus (or sometimes just cereus) is used to describe any of the species of cacti with very elongated bodies, including columnar growth cacti and epiphytic cacti. The name is from the Latin '' cēreus'', wax taper (slender candle), referring to the stiff, upright form of the columnar species. Some species of ceroid cacti were known as torch cactus or torch-thistle, supposedly due to their use as torches by Native Americans in the past.: "any of several columnar cacti of the genus ''Cereus'' whose stems were used by No. American Indians for torches." The genus '' Cereus'' was first genus for such cacti and one of the oldest cactus genera. Its circumscription varies depending on the authority. According to Cactiguide the word "cereus" was commonly and freely used to describe any tree-like cacti, although this general use of the word is regarded as misleading and the word ceroid or ceriform is preferred. Taxonomy The name ''cereus'' originates in a book by Taberna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Histeridae
Histeridae is a family of beetles commonly known as clown beetles or Hister beetles. This very diverse group of beetles contains 3,900 species found worldwide. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their geniculate (elbowed) antennae with clubbed ends. These predatory feeders are most active at night and will fake death if they feel threatened. This family of beetles will occupy almost any kind of niche throughout the world. Hister beetles have proved useful during forensic investigations to help in time of death estimation. Also, certain species are used in the control of livestock pests that infest dung and to control houseflies. Because they are predacious and will even eat other Hister beetles, they must be isolated when collected. Characteristics The Hister beetles are easily identified by their shiny elytra which is typically shiny black or metallic green. The two main shapes for this family are oval a ...

Histeroidea
Histeroidea is a superfamily of beetles in the infraorder Staphyliniformia. Characteristics Characteristic to Histeroidea are an accessory posterior ridge (locking device) behind the hind margin and presence of medial loop and apical hinge of wing. The elytra are truncate with 1 or 2 abdominal segments visible. The abdominal 8th segment is completely invaginated in the 7th segment. Each antenna has 8 (seldom 7) segments preceding a club of fused segments. The ventral body surface is glabrous.Hansen, MPhylogeny and classification of the staphyliniform beetle families (Coleoptera) Biologiske Skrifter, Copenhagen, 1997 Ecology Histeroids in general are predators. However, Sphaeritidae is believed to only be predatory in the larval stage, with its adults being saprophagous instead. This superfamily occurs in various habitats. The Histeridae alone can be found in dung, carrion, fungi, leaf litter, in symbiosis with other animals (e.g. social insects), under tree bark or in gal ...

Elytra
An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alternatively spelled as "hemielytra"), and in most species only the basal half is thickened while the apex is membranous, but when they are entirely thickened the condition is referred to as "coleopteroid". An elytron is sometimes also referred to as a shard. Description The elytra primarily serve as protective wing-cases for the hindwings underneath, which are used for flying. To fly, a beetle typically opens the elytra and then extends the hindwings, flying while still holding the elytra open, though many beetles in the families Scarabaeidae and Buprestidae can fly with the elytra closed (e.g., most Cetoniinae; ). In a number of groups, the elytra are reduced to various degrees, (e.g., the beetle families Staphylinidae and Ripiphoridae), or ...

Abdomen
The abdomen (colloquially called the belly, tummy, midriff, tucky or stomach) is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The abdomen is the front part of the abdominal segment of the torso. The area occupied by the abdomen is called the abdominal cavity. In arthropods it is the posterior (anatomy), posterior tagma (biology), tagma of the body; it follows the thorax or cephalothorax. In humans, the abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between Lumbar vertebrae, L5 and Vertebra#Sacrum, S1) to the pubic symphysis and is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear. In vertebrates, the abdomen is a large body c ...

Empodium
''Empodium'' is a genus of flowering plants in the family Hypoxidaceae, first described in 1866. It grows from a small corm which produces lance-shaped or pleated and sometimes hairy, star-shaped flowers and leaves with long in Autumn season. The genus is native to winter-rainfall areas in South Africa, Eswatini, Lesotho, and Namibia. ;Species # '' Empodium elongatum'' (Nel) B.L.Burtt - Lesotho, Eswatini, Lesotho # '' Empodium flexile'' (Nel) M.F.Thomps. ex Snijman - Cape Province The Province of the Cape of Good Hope ( af, Provinsie Kaap die Goeie Hoop), commonly referred to as the Cape Province ( af, Kaapprovinsie) and colloquially as The Cape ( af, Die Kaap), was a province in the Union of South Africa and subsequen ... # '' Empodium gloriosum'' (Nel) B.L.Burtt - Cape Province # '' Empodium monophyllum'' (Nel) B.L.Burtt - KwaZulu-Natal, Eswatini # '' Empodium namaquensis'' (Baker) M.F.Thomps. - Cape Province # '' Empodium plicatum'' (Thunb.)

Arthropod Leg
The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) are of Latin origin, and may be confused with terms for bones: ''coxa'' (meaning hip, plural ''coxae''), ''trochanter'', ''femur'' (plural ''femora''), ''tibia'' (plural ''tibiae''), ''tarsus'' (plural ''tarsi''), ''ischium'' (plural ''ischia''), ''metatarsus'', ''carpus'', ''dactylus'' (meaning finger), ''patella'' (plural ''patellae''). Homologies of leg segments between groups are difficult to prove and are the source of much argument. Some authors posit up to eleven segments per leg for the most recent common ancestor of extant arthropods but modern arthropods have eight or fewer. It has been argued that the ancestral leg need not have been so complex, and that other events, such as successive loss of function of a ''Hox''-gene, could result in parallel gains of leg segments. In arthropods, each of the leg segments ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two 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 touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a 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 if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched ...

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 ...

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 ...

Guatemala
Guatemala ( ; ), officially the Republic of Guatemala ( es, República de Guatemala, links=no), is a country in Central America. It is bordered to the north and west by Mexico; to the northeast by Belize and the Caribbean; to the east by Honduras; to the southeast by El Salvador and to the south by the Pacific Ocean. With an estimated population of around million, Guatemala is the most populous country in Central America and the 11th most populous country in the Americas. It is a representative democracy with its capital and largest city being Nueva Guatemala de la Asunción, also known as Guatemala City, the most populous city in Central America. The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica. In the 16th century, most of this area was conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence in 1821 from Spain and Mexico. In 1823, it became part of the Fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
