Oxypeltidae
The Oxypeltidae are a small family belonging to the superfamily Chrysomeloidea, widespread in the Andean region of Chile and Argentina. They have traditionally been considered a group within the Cerambycidae. Description The body is massive and characterised by metallic colour, bluish or green on the head and prothorax, and red on the elytra. Their antennae and legs have a blue metallic colour. The head, round and small, has two robustly toothed antennae, the pronotum is furnished with longitudinal crests, and the elytra, covered by strong puncture, are bidentate at the apex. The posterior wings, membranous, have an unusual violet colour, while they are transparent or brownish in cerambycids. Biology The larvae, typically xylophagous, attack trees of the genus ''Nothofagus'', the vicariant of beeches in the Southern Hemisphere. The adults are diurnal and can often be found on leaves. Systematics They have always been a mystery for specialists since these insects do not show ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheloderus Childreni
''Cheloderus childreni'' is a species of beetle belonging to the family Oxypeltidae. Description ''Cheloderus childreni'' can reach a length of about . This species, traditionally classified within the Cerambycidae and recently included in a new Oxypeltidae family, do not have any morphologic resemblance with the other cerambycids. The body is massive and characterised by a nice metallic colour, green on head and prothorax, and red on elytra. Their Antenna (biology), antennae and legs have a blue metallic colour. The head, round and small, has two robustly toothed antennae, the pronotum is furnished with two lateral ridges, and the elytra, covered by strong puncture, are bitoothed at the apex. The posterior wings are membranous and unusually pigmented in respect of all other groups of cerambycids. Larvae, typically xylophagy, xylophagous, bore under the bark of coigue (''Nothofagus dombeyi'', Nothofagaceae), the vicariant of beeches in the Southern Hemisphere. Distribution This ...

Chrysomeloidea
The Chrysomeloidea are an enormous superfamily of beetles, with tens of thousands of species. The largest families are Cerambycidae, long-horned beetles, with more than 35,000 species, and Chrysomelidae, leaf beetles, with more than 13,000 species. Overview The Chrysomeloidea, like all other Phytophaga, typically have the fourth tarsal segment reduced and hidden by the third segment. Several species in these two families are important plant pests. The spotted cucumber beetle is a serious pest of vegetables and is a very common insect on all sorts of flowers. The Colorado potato beetle, ''Leptinotarsa decemlineata'', attacks potatoes and other members of the Solanaceae. The Asian long-horned beetle is a serious pest of trees where it has been introduced. . It seems almost evident that during the Jurassic and the Cretaceous the Chrysomelidae were pollen feeders and then they became external and later on internal feeders on or in leaves, buds, twigs and roots.

Disteniidae
The Disteniidae are a small family of beetles in the superfamily Chrysomeloidea, traditionally treated as a group within the Cerambycidae (most resembling certain Lepturinae such as the genus '' Stenocorus'', but having long fine antennae and sometimes metallic colours). Morphology Adult The adults have a lepturoid aspect, having like those (except for a small number of cases) a divided stridulatory area. Nevertheless, the head is extremely short, the mandibles are strongly bowed and the anterior coxae are globular. The antennae are long, nearly filiform in most of the genera, and bearing very long setae in the Malagasy genus '' Nethinius''. Larva The major differences are in the larval morphology, because they have the prosternal skin attached to the base of the submentum, rather than with the gula such as all other Cerambycidae. For nearly all other aspects, they are very similar to the larvae of Lepturinae. Distribution This family, original from Gondwana, includes mo ...

Cerambycidae
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns, are a large family of beetles, with over 35,000 species described. Most species are characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short (e.g., '' Neandra brunnea'') and such species can be difficult to distinguish from related beetle families such as the Chrysomelidae. The scientific name of this beetle family goes back to a figure from Greek mythology: after an argument with nymphs, the shepherd Cerambus was transformed into a large beetle with horns. Description Other than the typical long antennal length, the most consistently distinctive feature of the family is that the antennal sockets are located on low tubercles on the face; other beetles with long antennae lack these tubercles, and cerambycids with short antennae still possess them. They otherwise vary greatly in size, shap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vesperidae
The Vesperidae are a small family of beetles, normally classified within the family Cerambycidae, of heterogeneous aspect but all characterised by larval stages related to roots of herbaceous plants or trees Morphology Adult The nocturnal adults are characterised by earthy brown-testaceous colours, brachypterous wings or apterous (especially in females) and physogastry in females. Some tropical genera ('' Pathocerus'') have comb-like antennae, some other (''Hypocephalus'') extremely reduced antennae. Some genera, such as the Brazilian '' Migdolus'' have well-developed mandibles, such as the males of the cerambycids '' Parandra'' and '' Spondylis'', while others, such as the males of the genus ''Hypocephalus'', have extremely modified mandibles. Larva The larvae have evolved some adaptations to subterranean life. In particular, the Mediterranean genus '' Vesperus'' have larvae characterised by a peculiar larval hypermetamorphosis. The larvae I have a normal worm-like aspect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prioninae
The Prioninae are a subfamily of Cerambycidae (long-horned beetles). They are typically large (25–70 mm) and usually brown or black. The males of a few genera sport large mandibles that are used in fights with other males, similar to stag beetles. These beetles are commonly nocturnal and are attracted to light. The majority of the Prioninae whose biology is known are borers whose larvae feed on rotting wood or roots. Genera The following genera are recognised in the subfamily Prioninae: * '' Acalodegma'' * '' Acanthinodera'' * '' Acanthophorus'' * '' Acideres'' * '' Aegolipton'' * '' Aegosoma'' * '' Aerogrammus'' * ''Aesa'' * '' Afraustraloderes'' * '' Agrianome'' * '' Allaiocerus'' * '' Allomallodon'' * '' Anacolus'' * '' Analophus'' * '' Ancistrotus'' * '' Andinotrichoderes'' * '' Anoeme'' * '' Anomophysis'' * '' Anomotoma'' * '' Anoplotoma'' * '' Anthracocentrus'' * '' Aplagiognathus'' * '' Apocaulus'' * '' Apterocaulus'' * '' Arba'' * '' Archetypus'' * '' Archodontes' ...
