Formiscurra
''Formiscurra'' is a genus of planthopper in the family Caliscelidae with two species: ''Formiscurra indicus'' of southern India and '' Formiscurra atlas'' from southwestern Ethiopia. Like others of its family they have short wings, suck plant sap and escape by leaping. The species shows great sexual dimorphism Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most ani .... The males of this half centimeter-long insect have an enlarged lobe in front of its head, the frons or metope, giving it an ant-like appearance. Females do not have such an enlarged structure but have a slightly long snout and differ slightly in body shape. The species is found mainly on low vegetation in open scrub and grass habitats. It has been suggested, based on the Afro-Indian distribution, that the ancestral species o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formiscurra Indicus
''Formiscurra indicus'' is a species of planthopper in the family Caliscelidae found in southern India. A related species, '' Formiscurra atlas'' occurs in southwestern Ethiopia. Like others of its family they have short wings, suck plant sap and escape by leaping. The species shows great sexual dimorphism. The male of this half centimeter-long insect has an enlarged lobe in front of its head, the frons or metope, giving it an ant-like appearance. Females do not have such an enlarged structure but have a slightly long snout and differ slightly in body shape. The species is found mainly on low vegetation in open scrub and grass habitats. Discovery This species was described in 2011 on the basis of specimens collected from around southern India from as far back as 1978. The holotype was collected in the campus of the University of Agricultural Sciences at Bangalore in the state of Karnataka in India. Other specimens have been collected from a widely separated locations in souther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caliscelidae
Caliscelidae is a family of planthoppers, sap-sucking insects that belong to the order Hemiptera, suborder Auchenorrhyncha and superfamily Fulgoroidea. They are somewhat anomalous and have often been included within the family Issidae. Studies made in 2013 of the phylogeny of the Issidae and other groups using molecular techniques support the treatment of the group as a separate family. Sexual dimorphism can be marked. Some members of the family are called piglet bugs due to the shape of their snout. A particularly aberrant genus described in 2011 from India, '' Formiscurra'', has males that resemble ants.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Planthopper
A planthopper is any insect in the infraorder Fulgoromorpha, in the suborder Auchenorrhyncha, a group exceeding 12,500 described species worldwide. The name comes from their remarkable resemblance to leaves and other plants of their environment and that they often "hop" for quick transportation in a similar way to that of grasshoppers. However, planthoppers generally walk very slowly. Distributed worldwide, all members of this group are plant-feeders, though surprisingly few are considered pests. The infraorder contains only a single superfamily, Fulgoroidea. Fulgoroids are most reliably distinguished from the other Auchenorrhyncha by two features; the bifurcate ("Y"-shaped) anal vein in the forewing, and the thickened, three-segmented antennae, with a generally round or egg-shaped second segment (pedicel) that bears a fine filamentous arista. Overview Planthoppers are laterally flattened and hold their broad wings vertically, in a tent-like fashion, concealing the sides of t ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auchenorrhyncha Genera
The Auchenorrhyncha suborder of the Hemiptera contains most of the familiar members of what was called the "Homoptera" – groups such as cicadas, leafhoppers, treehoppers, planthoppers, and spittlebugs. The aphids and scale insects are the other well-known "Homoptera", and they are in the suborder Sternorrhyncha. Distributed worldwide, all members of this group are plant-feeders, and many are vectors of viral and fungal diseases of plants. It is also common for Auchenorrhyncha species to produce either audible sounds or substrate vibrations as a form of communication. Such calls range from vibrations inaudible to humans, to the calls of many species of cicadas that can be heard for hundreds of metres, at least. In season, they produce the most characteristic and ubiquitous noise of the bush. Etymology The word auchenorrhyncha is from the Greek αὐχήν, 'neck, throat' and ῥύγχος, 'snout'. Classification Debate and uncertainty as to whether the Auchenorrhyncha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Described In 2011
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] |
