Ischnura Rubilio
''Ischnura rubilio'', western golden dartlet, is a species of damselfly in the family Coenagrionidae. It is found in Indian subcontinent and Iran. Earlier it was considered as a subspecies of ''Ischnura aurora'', distributed from Australia and Pacific Islands. There are strong differences in DNA between the Asian forms of the species and specimens from the Pacific. There is also some Morphology (biology), morphological differences; dorsal side of segment 8 and 9 are entirely blue in Asian forms compared to only 1/3 of length of segment 8 is blue in specimens from the Pacific. The form found in Indian subcontinent and Iran is ''Ischnura aurora rubilio'' Selys, 1876 and is now considered as a good species, ''Ischnura rubilio''. Description and habitat It is a small apple green damselfly with black thoracic stripes, black capped olive green eyes, and blue tipped yellow tail. Its thorax is bronzed black color on dorsal side with narrow olive green antehumeral stripes. The lateral sid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
