Synetinae
The Synetinae are a small subfamily within the leaf beetle family (Chrysomelidae). They are found entirely within the Holarctic, mainly in North America but also appearing in parts of Europe Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east ... and Asia. The subfamily contains only two genera, ''Syneta'' and ''Thricolema'', with a total of 12 described species. The group is sometimes treated as a tribe of Eumolpinae, where they are known as Synetini. Classification Historically, the genera ''Syneta'' and ''Thricolema'' were placed within the Orsodacnidae, which was formerly considered a subfamily within the Chrysomelidae. The family-group name was first proposed as "Synetae" in 1883 by John Lawrence LeConte and George Henry Horn, though it is often attributed instead to J. Gordon Edwa ...

Syneta
''Syneta'' is a genus of leaf beetles in the subfamily Synetinae. There are about 11 described species in ''Syneta''. The genus is entirely holarctic in distribution, with species appearing in North America, Siberia, East Asia and Northern Europe. Nomenclature The generic name ''Syneta'', derived from the Greek word meaning "sagacious", was first used by Eschscholtz in his collection, though he never published it. ''Syneta'' was then listed in the last two editions of Dejean's Catalogue of Coleoptera. No characters for the genus were mentioned in the Catalogue, though three species were listed; of these species, only one ('' Syneta betulae'') was considered valid, the other two being ''nomina nuda'', automatically making it the type species of the genus. Because of its inclusion in the Catalogue with a valid species, the name ''Syneta'' should be attributed to Dejean, though it has also been attributed to Lacordaire, who was the first to publish it with a description in 1845. ...

Thricolema
''Thricolema'' is a genus of leaf beetles in the subfamily Synetinae. It contains only one species, ''Thricolema anomala'', known from California and Oregon in the United States. ''Thricolema'' resembles ''Syneta'', except that the adult females of ''Thricolema'' have simple tarsal claws, whereas adults of both sexes of ''Syneta'' have bifid claws. The body of an adult is elongated and fibrous. Adults are associated with ''Calocedrus decurrens ''Calocedrus decurrens'', with the common names incense cedar and California incense cedar (syn. ''Libocedrus decurrens'' Torr.), is a species of coniferous tree native to western North America. It is the most widely known species in the genus, ...''.

Leaf Beetle
The beetle family Chrysomelidae, commonly known as leaf beetles, includes over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making it one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research. Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5 as the fourth tarsal segment is very small and hidden by the third. As with many taxa, no single character defines Chrysomelidae; instead, the family is delineated by a set of characters. Some lineages are only distinguished with difficulty from longhorn beetles (family Cerambycidae), namely by the antennae not arising from frontal tubercles. Members of former chrysomelid subfamilies ( Orsodacnidae and Megalopodidae) are also difficult to differentiate from true chrysomelids. Adult and larval leaf beetles feed o ...

Eumolpinae
The Eumolpinae are a subfamily of the leaf beetles, or Chrysomelidae. It is one of the largest subfamilies of leaf beetles, including more than 500 genera and 7000 species. They are oval, and convex in form, and measure up to 10 mm in size. Typical coloration for this subfamily of beetles ranges from bright yellow to dark red. Many species are iridescent or brilliantly metallic blue or green in appearance. Description Eumolpinae can be recognized at first sight by their rounded thoraces, more or less spherical or bell-shaped, but always significantly narrower than the mesothorax as covered by the elytra. Additional features include a small head set deeply into the thorax, and usually well-developed legs. They generally resemble other Chrysomelidae, but differ in having front coxae rounded and third tarsal segment bilobed beneath. Many are metallic, or yellow and spotted. The dogbane beetle (''Chrysochus auratus''), for instance, is very attractive—iridescent blue-green wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Henry Horn
George Henry Horn (April 7, 1840 – November 24, 1897) was an American entomology, entomologist who specialized in the study of beetles. Biography Born in Philadelphia on April 7, 1840, Horn attended the University of Pennsylvania, from which he graduated with a degree in medicine in 1861. From 1862 to 1866, he served in the American Civil War as surgeon to the infantry of the List of California Civil War Union units, California Volunteers, during which time he collected insects extensively in California, Arizona, and New Mexico. He then returned to Philadelphia, where he established a medical practice, specializing in obstetrics, and was elected president of the Entomological Society of Philadelphia, the predecessor of the American Entomological Society. He would remain president of the latter society until his death. He was elected as a member of the American Philosophical Society in 1869 and was the librarian and one of the secretaries of the society at the time of his dea ...

Holarctic
The Holarctic realm is a biogeographic realm that comprises the majority of habitats found throughout the continents in the Northern Hemisphere. It corresponds to the floristic Boreal Kingdom. It includes both the Nearctic zoogeographical region (which covers most of North America), and Alfred Wallace's Palearctic zoogeographical region (which covers North Africa, and all of Eurasia except for Southeast Asia, the Indian subcontinent, the southern Arabian Peninsula). These regions are further subdivided into a variety of ecoregions. Many ecosystems and the animal and plant communities that depend on them extend across a number of continents and cover large portions of the Holarctic realm. This continuity is the result of those regions’ shared glacial history. Major ecosystems Within the Holarctic realm, there are a variety of ecosystems. The type of ecosystem found in a given area depends on its latitude and the local geography. In the far north, a band of Arctic tun ...

Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east.

Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...
