Esme (genus)
''Esme'' is a genus of damselflies in the family Platycnemididae The Platycnemididae are a family of damselflies. They are known commonly as white-legged damselflies. There are over 400 species native to the Old World.Dijkstra, K. D. B., Kalkman, V. J., Dow, R. A., Stokvis, F. R., & Van Tol, J. (2014)Redefini .... This genus has three species. The following are the species: *'' Esme cyaneovittata'' *'' Esme longistyla'' (Nilgiri bambootail) *'' Esme mudiensis'' References Platycnemididae {{Platycnemididae-stub ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Damselfly
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica. All damselflies are predatory insects; both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, bu ...

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 opi ...

Platycnemididae
The Platycnemididae are a family of damselflies. They are known commonly as white-legged damselflies. There are over 400 species native to the Old World.Dijkstra, K. D. B., Kalkman, V. J., Dow, R. A., Stokvis, F. R., & Van Tol, J. (2014)Redefining the damselfly families: a comprehensive molecular phylogeny of Zygoptera (Odonata).''Systematic Entomology'', 39(1), 68-96. The family is divided into several subfamilies. Genera There are about 50 genera of Platycnemididae.Theischinger, G., Gassmann, D., & Richards, S. J.

Esme Cyaneovittata
''Esme cyaneovittata'' is damselfly in the family Platycnemididae. It is endemic to Western Ghats in India, south of Palakkad Gap. Description and habitat It is a medium-sized damselfly with black-capped blue eyes. Its thorax is velvet-black on dorsum and azure blue on sides. The dorsum is marked with narrow ante-humeral blue stripes. There is another moderately broad black stripe over the postero-lateral suture. The base of the sides is pale blue. Wings are transparent with black pterostigma. Abdomen is black, marked with azure blue on segment 1 and 2. Segments 3 to 7 have very narrow baso-dorsal annules. Segments 8 to 10 are blue. The apical border of 10 and the ventral borders of all segments are broadly black. Anal appendages are black. Female is similar to the male; but more robustly build. It can be distinguished from '' Esme mudiensis'' from its labrum marked with blue. From '' Esme longistyla'', it can be distinguished by its black legs unmarked with blue, by its stout i ...

Esme Longistyla
''Esme longistyla'' is damselfly in the family Platycnemididae. It is commonly known as the Nilgiri bambootail. It is endemic to Western Ghats in India. Description It is medium-sized damselfly with about abdomen and hindwings about with black-capped blue eyes. Its thorax is velvet-black on dorsum and azure blue on sides. The dorsum is marked with narrow ante-humeral blue stripes. There is another moderately broad black stripe over the postero-lateral suture. The base of the sides are pale blue. The under side of the thorax is greenish yellow or blue. The legs of the males are black. The abdomen is long and slender. The first and 8–10 segments on the abdomen are azure blue. The second segment of the damselfly is black with board irregular azure blue stripes on sides of abdomen. The segments from 3–7 are black with azure blue rings at the end of each segment. The segments 8 to 10 are azure blue; but the sides of segment 10 and apical border are narrowly black. Anal appendag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
