Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostyl ...

Beetles
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, Elytron, 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 fungus, 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.

Staphylinidae
The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed. With roughly 63,000 species in thousands of genera, the group is currently recognized as the largest extant family of organisms. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus ''Leehermania'' proves to be a member of this family. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems. One well-known species is the devil's coach-horse beetle. For some other species, see list of British rove beetles. Anatomy As might be expected for such a large family, considerable variation exists among the species. Sizes range from <1 to , with most in the 2–8 mm range, and the form is generally elongated, with some rove beetles being ovoid i ...

William Elford Leach
William Elford Leach FRS (2 February 1791 – 25 August 1836) was an English zoologist and marine biologist. Life and work Elford Leach was born at Hoe Gate, Plymouth, the son of an attorney. At the age of twelve he began a medical apprenticeship at the Devonshire and Exeter Hospital, studying anatomy and chemistry. By this time he was already collecting marine animals from Plymouth Sound and along the Devon coast. At seventeen he began studying medicine at St Bartholomew's Hospital in London, finishing his training at the University of Edinburgh before graduating MD from the University of St Andrews (where he had never studied). From 1813 Leach concentrated on his zoological interests and was employed as an 'Assistant Librarian' (what would later be called Assistant Keeper) in the Natural History Department of the British Museum, where he had responsibility for the zoological collections. Here he threw himself into the task of reorganising and modernising these coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velleius Dilatatus
''Velleius dilatatus'' , the hornet rove beetle, is a species of rove beetle belonging to the family Staphylinidae. This beetle is commensal with the European hornet (''Vespa crabro''), living in its nests. Taxonomy ''Velleius dilatatus'' was first formally described in 1787 as ''Staphylinus dilatatus'' by the Danish biologist Johan Christian Fabricius with its type locality given as Saxony ("''Halae Saxonum''"). This species is classified within the genus ''Quedius'' by some authorities who treat ''Velleius'' as a subgenus of ''Quedius''. Description ''Velleius dilatatus'' is a large species of rove beetle being between , and is completely black or dark brown in colour with a rounded, laterally flattened pronotum. They have a large head with weakly convex eyes and long and curved temples, The surface of the exoskeleton is matt because there is strong microsculpture. The mandibles are large and asymmetrical; the right mandible has a prominent tooth and the left has 3 smaller tee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
