Coleopsidae
''Coleopsis'' is an extinct genus of stem-group beetles. It contains a single species, ''Coleopsis archaica'', and is the only member of the family Coleopsidae. It is known from a single specimen from the Early Permian (Asselian) Meisenheim Formation of western Germany, estimated to be about 297 million years old. It is currently the oldest known beetle. Taxonomy and systematics While originally interpreted as a member of the family Tshekardocoleidae, this interpretation has been revised and questioned, with the most recent analyses suggesting that it is best placed in its own family, and may be the sister group to all other beetles. The family name was originally published in 2016 as "Coleopsidae" but a later publication claimed that this spelling was erroneous and proposed the spelling "Coleopseidae"; however, under the ICZN, Article 29.4, family-rank names originally published after 1999 are not subject to emendation because of incorrect spelling, so Coleopsidae would be maint ...

Tshekardocoleidae
Tshekardocoleidae is an extinct family of stem group beetles, known from the Permian. They represent some of the earliest known beetles. They first appeared during the Cisuralian, before becoming extinct at the beginning of the Guadalupian. A claimed Jurassic record is doubtful. Like other primitive beetles, they are thought to have been xylophagous. The oldest known beetle, '' Coleopsis,'' was originally assigned to this family, but is now assigned to its own family Coleopsidae. The Tshekardocoleidae are thought to have retained several plesiomorphies (ancestral characters) of Coleoptera in a broad sense. For instance, their elytra are flattened, lack epipleura (outer margins), cover the body loosely, and their tips extend beyond the apex of the abdomen. Their abdomens have a nearly cylindrical shape and are thought to have been flexible, apparently being able to strongly contract and expand. In extant beetles, the elytra are tight-fitting, forming a subelytral space which is abs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boris Rohdendorf
Boris Borisovich Rohdendorf (, 12 July 1904, Saint Petersburg – 21 November 1977, Moscow) was a Soviet entomologist and curator at the Zoological Museum at the Moscow University. He attained the position of head of the Laboratory of Arthropods, Paleontological Institute, Russian Academy of Sciences, Academy of Sciences of the Soviet Union in Moscow. A student of Andrey Martynov, he was a prolific taxonomist who described numerous new taxa, including fossil Diptera, and published important syntheses on fossil insects. His work was a basis for many Russian paleoentomologists. Rohdendorf was born near St. Petersburg where his father was an army man. He studied at the natural science department of the Moscow University and from 1921 he worked as a taxonomist at the zoological museum of the university. He took a special interest in the Diptera, examining the Tachinidae, Phasiidae, Calliphoridae and Sarcophagidae. In 1923 he described a new Phasiinae from Turkmenistan. He graduated ...

Protocoleoptera
The Protocoleoptera are a Paraphyly, paraphyletic group of extinct beetles, containing the earliest and most primitive lineages of beetles. They represented the dominant group of beetles during the Permian, but were largely replaced by modern beetle groups during the following Triassic. Protocoleopterans typically possess prognathous (horizontal) heads, distinctive elytra with regular window punctures, Arthropod cuticle, cuticles with tubercles or scales, as well as a primitive pattern of ventral sclerites, similar to the modern Archostemata, archostematan families Ommatidae and Cupedidae. They are thought to have been Xylophagy, xylophagous and Woodboring beetle, wood boring. Nomenclature Protocoleoptera was originally proposed by Robert John Tillyard in 1924 for the extinct genus ''Protocoleus'', assigned to the family Protocoleidae. ''Protocoleus'' is now considered a member of the extinct order Protelytroptera (a stem-group of the modern Dermaptera, the earwigs), which would m ...

Beetle Superfamilies
Beetles are insects that form the order Coleoptera (), in the superorder Holometabola. 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 arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in dipterans (flies) and hymenopterans (wasps). 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 ...
