Sphegina Kumaoniensis
''Sphegina kumaoniensis'' is a species of hoverfly in the family Syrphidae found in India, Thailand, and northeast Myanmar. It's characterized by a convex dorsal line of frontal prominence that ends clearly before the ocellar triangle as well as a mouthedge less strongly projecting, vibrissal angle less protruding or equal with the frontal prominence. Etymology The name comes the Kumaon division where it was originally discovered. Related Species ''S. kumaoniensis'' is very similar to '' S. uncinata'' and it's difficult to tell the two apart without reference to the male genitalia, in which they can be distinguished by ''S. kumaoniensis horn-like process of the baso-dorsal superior lobe (absent in ''S. uncinata''), broad and latero-ventrally curved apical part of the superior lobe (in ''S. uncinata'' it's narrow and dorsally curved), and surstylus narrowed on the apical half with a concave medial margin (in ''S. uncinata'' it's short and evenly broad from dorsal view).

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoverfly
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most mammals, ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Kumaon Division
Kumaon (; Kumaoni: ''Kumāū''; ; historically romanized as KemāonJames Prinsep (Editor)John McClelland ) is a revenue and administrative division in the Indian State of Uttarakhand. It spans over the eastern half of the state and is bounded on the north by Tibet, on the east by Nepal, on the south by the state of Uttar Pradesh, and on the west by Garhwal. Kumaon comprises six districts of the state: Almora, Bageshwar, Champawat, Nainital, Pithoragarh and Udham Singh Nagar. Historically known as Manaskhand and then Kurmanchal, the Kumaon region has been ruled by several Hindu dynasties over the course of history; most notably the Katyuris and the Chands. The Kumaon division was established in 1816, when the British reclaimed this region from the Gorkhas, who had annexed the erstwhile Kingdom of Kumaon in 1790. It was formed into a division of what was then called Ceded and Conquered Provinces, later known as United Provinces. In independent India the state was called Utt ...

Sphegina Uncinata
''Sphegina uncinata'' is a species of hoverfly in the family Syrphidae found in Myanmar. It's easily identified by a straight dorsal line of frontal prominence that ends just before the ocellar triangle, a strongly projecting mouth edge, and a vibrissal angle more strongly protruding than the frontal prominence. Etymology The name comes from Latin 'uncinata', meaning 'hooked', referring to the hooked posterior part of the male superior lobe. Description In male specimens, the body length is 4.5 to 5.8 millimeters and the wing length is 4.7 to 5.5 millimeters. The face is strongly concave with a large frontal prominence. The face is dorsally blackish, ventrally paler yellowish or brownish; gena yellow; lunula brown or yellow; occiput dull black; antenna brown, scape and pedicel usually not darker than the basal flagellomere; Colour dark brown, postpronotum and postalar callus yellow or brownish; pro- and mesoleg yellow; metaleg has a brown coxa, simple yellow trochanter, da ...

Brachyopini
The Brachyopini (or Chrysogastrini) is a tribe of hoverflies. Unlike many members of this family these flies are generally darker and less colourful though some genera contain species with an attractive metallic lustre e.g. ''Chrysogaster''. Some like '' Brachyopa'' are associated with sap runs where their larvae feed on decaying sap. Others are found in boggy areas where their often semiaquatic larvae feed on decaying organic matter.

Insects Described In 1998
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
