Mecodema Aoteanoho
''Mecodema aoteanoho'' is a medium-sized (19–24 mm length, 5.5–7 mm width) ground beetle, the only such beetle endemic to Great Barrier Island (Aotea), Hauraki Gulf, Auckland, New Zealand. ''Mecodema aoteanoho'' is a sister species to '' M. haunoho'' ( Little Barrier Island) and is closely related to the Coromandel (mainland) species, '' M. atrox'', all of which are species within the monophyletic ''curvidens'' group (4–6 setae along each side of the prothoracic carina). There are a number of other characters that distinguish ''M. aoteanoho'' from all other North Island ''Mecodema ''Mecodema'' is a genus of large flightless ground beetle (Carabidae) endemic to New Zealand.

Ground Beetle
Ground beetles are a large, cosmopolitan distribution, cosmopolitan family (biology), 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 arthropod leg, fore leg tibiae bearing a comb of hairs used for cleaning their antenna (biology), antennae. ...

Mecodema Haunoho
''Mecodema haunoho'' is the only ground beetle ( Carabidae) species that is endemic to Little Barrier Island (Hauturu). It is sister species of the Great Barrier Island (Aotea) species '' M. aoteanoho'' and both are closely related to ''M. manaia'', a species found in Bream Head, Northland, New Zealand.

Little Barrier Island
Little Barrier Island, or Hauturu in Māori language (the official Māori title is ''Te Hauturu-o-Toi''), lies off the northeastern coast of New Zealand's North Island. Located to the north of Auckland, the island is separated from the mainland to the west by Jellicoe Channel, and from the larger Great Barrier Island to the east by Cradock Channel. The two aptly named islands shelter the Hauraki Gulf from many of the storms of the Pacific Ocean. Settled by the Māori between 1350 and 1650, the island was occupied by them until the New Zealand government declared the island a wildlife sanctuary in 1897. Since the island came under control of the government, it has been under limited access, with only a few rangers living on the island. In the Māori language, the name of the island name means "the resting place of lingering breezes". Along with its larger neighbour Great Barrier, it was given its English name by Captain James Cook in 1769. The island is a nature sanctuary whic ...

Coromandel Peninsula
The Coromandel Peninsula ( mi, Te Tara-O-Te-Ika-A-Māui) on the North Island of New Zealand extends north from the western end of the Bay of Plenty, forming a natural barrier protecting the Hauraki Gulf and the Firth of Thames in the west from the Pacific Ocean to the east. It is wide at its broadest point. Almost its entire population lives on the narrow coastal strips fronting the Hauraki Gulf and the Bay of Plenty. In clear weather the peninsula is clearly visible from Auckland, the country's biggest city, which lies on the far shore of the Hauraki Gulf, to the west. The peninsula is part of the Thames-Coromandel District of the Waikato region. Origin of the name The Māori name for the Coromandel comes from the Māori legend of Māui and the Fish, in which the demigod uses his hook to catch a great fish from the depths of te Moana-Nui-a-Kiwa (The Pacific Ocean). ''Te Tara-O-Te-Ika-A-Māui'' means 'The spine of Māui's fish'. The spine can be understood to be the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mecodema Atrox
''Mecodema atrox'' is a medium-sized (17–24 mm length, 6–8 mm width) ground beetle species that is closely related to ''Mecodema curvidens'' (a very widespread species throughout the Bay of Plenty and Central Plateau). ''Mecodema atrox'' is relatively rare in comparison due to its preferred habitat, the coastal broadleaf forests of the Coromandel Peninsula, a forest type that is in decline. The body of ''Mecodema atrox'' is black and the legs are dark reddish-brown. They can be distinguished from other ''Mecodema'' species by a number of characters, including the pattern of asetose punctures along the elytral striae. This species is part of the ''curvidens'' group that has a geographical distribution from Northland (including the Three Kings Island) to Banks Peninsula, South Island. Species of the ''curvidens'' group predominantly follow an eastern distribution including species on the offshore islands (e.g., Poor Knights Island, Hauturu (Little Barrier Island) a ...

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 ...

Elytron
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), o ...

Beetles Of New Zealand
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] |
