Mecodema Moniliferum
''Mecodema moniliferum'' is a medium-sized ground beetle endemic to the South island, New Zealand. This species is part of the monophyletic ''curvidens'' group and is found on the braided-river systems of the South Island. Diagnosis Distinguished from other ''Mecodema ''Mecodema'' is a genus of large flightless ground beetle (Carabidae) endemic to New Zealand. The genus is very diverse in comparison to the other three New Zealand genera ('' Diglymma'', '' Oregus'', '' Orthoglymma'') within the subtribe Noth ...'' species by having: # ventrites 4–5 bearing numerous setose punctures; # elytral striae defined anteriorly and laterally by large, irregularly spaced asetose punctures; # shape of basal lobe and setal distribution along ventral edge of left paramere. Description Length 14.6–19.5 mm, pronotal width 4.2–6.2 mm, elytral width 5.1–7.1 mm. Colour of entire body matte reddish-brown to matte black.

Henry Walter Bates
Henry Walter Bates (8 February 1825, in Leicester – 16 February 1892, in London) was an English naturalist and explorer who gave the first scientific account of mimicry in animals. He was most famous for his expedition to the rainforests of the Amazon with Alfred Russel Wallace, starting in 1848. Wallace returned in 1852, but lost his collection on the return voyage when his ship caught fire. When Bates arrived home in 1859 after a full eleven years, he had sent back over 14,712 species (mostly of insects) of which 8,000 were (according to Bates, but see Van Wyhe) new to science. Bates wrote up his findings in his best-known work, '' The Naturalist on the River Amazons''. Life Bates was born in Leicester to a literate middle-class family. However, like Wallace, T.H. Huxley and Herbert Spencer, he had a normal education to the age of about 13 when he became apprenticed to a hosiery manufacturer. He joined the Mechanics' Institute (which had a library), studied in his sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Beetle
Ground beetles are a large, cosmopolitan family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga. Members of the family are primarily carnivorous, but some members are phytophagous or omnivorous. Description and ecology Although their body shapes and coloring vary somewhat, most are shiny black or metallic and have ridged wing covers (elytra). The elytra are fused in some species, particularly the large Carabinae, rendering the beetles unable to fly. The species ''Mormolyce phyllodes'' is known as violin beetle due to their peculiarly shaped elytra. All carabids except the quite primitive flanged bombardier beetles (Paussinae) have a groove on their fore leg tibiae bearing a comb of hairs used for cleaning their antennae. Defensive secretions Typical for the ancient beetle suborder Adephaga to wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mecodema
''Mecodema'' is a genus of large flightless ground beetle (Carabidae) endemic to New Zealand. The genus is very diverse in comparison to the other three New Zealand genera ('' Diglymma'', '' Oregus'', '' Orthoglymma'') within the subtribe Nothobroscina (tribe Broscini). ''Mecodema'' is geographically widespread across both the North and South Islands, as well as numerous offshore islands, including the Three Kings Is., Poor Knights Is., Aotea ( Great Barrier Is.) and Hauturu (Little Barrier Is.), Kapiti Is., Stephens Is., Stewart Is., Chatham Is., Snares Is. Genus description Head, frons and vertex often rugose and / or punctate, microsculpture or macrosculpture absent in some species groups (e.g., ''curvidens'' species); eyes prominent, almost hemispherical; a single supraorbital puncture on each side, bearing more than one setae; setose punctures of vertex absent; mandibles large, uniformly narrow to the pointed apex, sharply curved in the apical third, mandibles ...

Beetles Described In 1867
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exoske ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Beetles Of New Zealand
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
