Ogcodes
''Ogcodes'' is a genus of small-headed flies in the family Acroceridae. About 90 species have been described for the genus. Subgenera and species The genus is split into three subgenera: ''Ogcodes'', ''Protogcodes'' and ''Neogcodes''. ''Ogcodes'' is cosmopolitan in distribution, ''Protogcodes'' is endemic to Australia, and ''Neogcodes'' is restricted to the Nearctic.

Acroceridae
The Acroceridae are a small family (biology), family of odd-looking flies. They have a hump-backed appearance with a strikingly small head, generally with a long proboscis for accessing nectar. They are rare and not widely known. The most frequently applied common names are small-headed flies or hunch-back flies. Many are bee or wasp mimicry, mimics. Because they are parasitoids of spiders, they also are sometimes known as spider flies. Description The Acroceridae vary in size from small to fairly large, about the size of large bees, with a wingspan over 25 mm in some species. As a rule, both sexes have tiny heads and a characteristic hump-backed appearance because of the large, rounded thorax. In appearance, they are compact flies without major bristles, but many species have a bee-like hairiness on their bodies, and some are bee or wasp mimicry, mimics. In most species, the eyes are holoptic in both sexes, the heads seemingly composed mainly of the large ommatidia, facete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Camillo Rondani
Camillo Rondani (21 November 1808 – 17 September 1879) was an Italian entomologist noted for his studies of Diptera. Early life, family and education Camillo Rondani was born in Parma when the city was part of the French Empire Napoleon having crowned himself King of Italy. The Rondani family were wealthy landowners and of "rich and of ancient origins" with ecclesiastical connections preliminary. Camillo's early education was in a seminary. He then passed into the public school system where, encouraged by Macedonio Melloni his physics and chemistry teacher in the preparatory course for the University of Parma, he did not attend the law lessons though his family had insisted. He attended mineralogy classes given by a Franciscan priest Father Bagatta and was taught natural history, a complementary course to botany for Medicine and Pharmacy. The Reader of Botany to the Athenaeum Parmesan was Professori Giorgio Jan, assistant at the Imperial Museum in Vienna and holder of the ...

Endoparasite
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entelegynae
The Entelegynae or entelegynes are a subgroup of araneomorph spiders, the largest of the two main groups into which the araneomorphs were traditionally divided. Females have a genital plate ( epigynum) and a "flow through" fertilization system; males have complex palpal bulbs. Molecular phylogenetic studies have supported the monophyly of Entelegynae (whereas the other traditional subgroup, the Haplogynae, has been shown not to be monophyletic). The clade contains both cribellate and ecribellate spiders. Characterization The Entelegynae are characterized primarily by the nature of the female genital system. The ancestral ( plesiomorphic) system is found in non-entelegyne spiders, where there is a single external genital opening in the female's abdomen. One or more males inject sperm from their palpal bulbs via this opening; the sperm is usually stored in special spermathecae (absent in some spiders, e.g. ''Pholcus''). When eggs are released from the ovaries, sperm is also releas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systematic Entomology
''Systematic Entomology'' is a scientific journal covering the field of systematic entomology, published by the Royal Entomological Society of London. Having begun in 1932 as '' Proceedings of the Royal Entomological Society of London, Series B: Taxonomy'', the title was changed to ''Journal of Entomology, Series B: Taxonomy'' in 1971, starting with volume 40. After volume 44 in 1976, the journal became ''Systematic Entomology'', starting again with volume 1. According to the ''Journal Citation Reports'', the journal has a 2020 impact factor of 3.844. It is indexed in the following bibliographic databases: *''Academic Search'' *''AGRICOLA'' *''Aquatic Sciences and Fisheries Abstracts'' *'' BIOBASE'' *''Biological Abstracts'' *''BIOSIS Previews'' *'' CAB Direct'' *'' CSA Biological Sciences Database'' *'' CSA Environmental Sciences & Pollution Management Database'' *''Current Contents'' *''Embiology'' *'' IBIDS'' *'' InfoTrac'' *''Journal Citation Reports'' *''Science Citation In ...

Willi Hennig
Emil Hans Willi Hennig (20 April 1913 – 5 November 1976) was a Germans, German biologist and zoologist who is considered the founder of Phylogenesis, phylogenetic systematics, otherwise known as cladistics. In 1945 as a POWs in World War II, prisoner of war, Hennig began work on his theory of cladistics, which he published in German in 1950, with a substantially revised English translation published in 1966. With his works on evolution and systematics he revolutionised the view of the natural order of beings. As a Taxonomy (biology), taxonomist, he specialised in dipterans (true flies). Hennig coined the key terms synapomorphy, Plesiomorphy and symplesiomorphy, symplesiomorphy, and paraphyly. He also asserted, in his "auxiliary principle", that "the presence of apomorphous characters in different species 'is always reason for suspecting kinship [i.e., that species belong to a monophyletic group], and that their origin by convergence should not be presumed a priori' (Hennig, 195 ...

Pierre André Latreille
Pierre André Latreille (; 29 November 1762 – 6 February 1833) was a French zoologist, specialising in arthropods. Having trained as a Roman Catholic priest before the French Revolution, Latreille was imprisoned, and only regained his freedom after recognising a rare beetle species he found in the prison, ''Necrobia ruficollis''. He published his first important work in 1796 (), and was eventually employed by the . His foresighted work on arthropod systematics and taxonomy gained him respect and accolades, including being asked to write the volume on arthropods for George Cuvier's monumental work, , the only part not by Cuvier himself. Latreille was considered the foremost entomologist of his time, and was described by one of his pupils as "the prince of entomologists". Biography Early life Pierre André Latreille was born on 29 November 1762 in the town of Brive, then in the province of Limousin, as the illegitimate child of Jean Joseph Sahuguet d'Amarzit, général ...

Brachycera Subfamilies
The Brachycera are a suborder of the order Diptera. It is a major suborder consisting of around 120 families. Their most distinguishing characteristic is reduced antenna segmentation. Description A summary of the main physical characteristics is: * Antenna size (with eight or fewer flagellomeres) is reduced. * The maxillary palp (an elongated appendage near the mouth) has two segments or fewer. * The back portions of the larval head capsule extend into the prothorax (the anterior part of the thorax, which bears the first pair of legs). * Two distinct parts make up of the larval mandible (lower jaw). * The epandrium and hypandrium of the genitalia are separated in males. * No premandible is present on the lower surface of the labrum (the roof of the mouth). * The configuration of the CuA2 and A1 wing veins is distinct. Brachyceran flies can also be distinguished through behavior. Many of the species are predators or scavengers. Classification The structure of subgroups with ...
