Oristicta Filicicola
''Oristicta filicicola'' is a species of damselfly belonging to the family Isostictidae. Until 2017 it was the only species of the genus ''Oristicta''. Commonly known as a slender wiretail, it is a slender and dull-coloured damselfly of medium-size. It is endemic to north-eastern Australia, where it inhabits streams in rainforests. Description Body ''Oristicta filicicola'' has olive-green eyes widely spaced on a small head. The synthorax is pale on the lower surface, graduating to a light green on the sides, with dark markings along the sutures. The upper surface is brown, outlined in black on the edges. The dorsal carina (mid-line ridge) is white on a dark background. The abdomen is long and slender, with a steel-like metallic-black on the upper surface, sharply cut off to cream ventral surfaces. At each segment join the paler colour sweeps up forming a narrow ring. On segments 9 and 10, the pale coloration sweeps up towards the rear, to form a dark wedge-shaped pattern on ...

Oristicta Rosendaleorum
''Oristicta rosendaleorum'' is a species of damselfly belonging to the family Isostictidae. It was described by Theischinger and Burwell in 2017. Until 2017 ''Oristicta filicicola'' was the only species of the genus ''Oristicta'' which has now been widened to include ''Oristicta rosendaleorum''. The common name suggested for the new species is elegant wiretail. Description ''Oristicta rosendaleorum'' is a slender and dull-coloured damselfly of medium-size with a length around 42mm, and hind-wing about 21mm . Differences when compared to ''Oristicta filicicola'' include richer black markings, altered patterns on the synthorax and abdominal segments, and a lack of posterolateral processes/horns on the male pronotum. The anal appendages of the male take a different form also. Distribution As of 2017, five specimens have been collected from two locations, both within 20 km of Lakeland, Queensland Lakeland is a rural town and Suburbs and localities (Australia), locality i ...

Isostictidae
Isostictidae is a family of small to medium-sized damselflies restricted to Australia, New Caledonia, and New Guinea New Guinea (; Hiri Motu: ''Niu Gini''; , fossilized , also known as Papua or historically ) is the List of islands by area, world's second-largest island, with an area of . Located in Melanesia in the southwestern Pacific Ocean, the island is .... It contains 12 genera and more than 40 species. Members of this family resemble species in the former threadtail family ( Protoneuridae). Diagnosis *Adult: The adults have a length of 15–40 mm. They have two antenodal crossveins, most postnodal crossveins aligned with crossveins behind them, quadrilateral cell almost rectangular, no supplementary intercalary longitudinal veins, and an anal vein fused with wing margin. Their antennae are seven-segmented. *Larva: Larvae have a labial mask, with short flat palps and narrow palpal setae. Premental setae are variable, median lobe is shallowly cleft; caudal gills ...

Taxa Named By Robert John Tillyard
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Australia
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Odonata Of Australia
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the '' Epiophlebia'' damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and wings folded together along body at rest. Adult odonates can land and perch, but rarely walk. All odonates have aquatic larvae called naiads or nymphs, and all of them, larvae and adults, are carnivorous and are almost entirely insectivorous, although at the larval stage they will eat anything that they can overpower, including small fish, tadpoles, and even adult newts. The adults are superb aerial hunters and their legs are specialised for catching prey in flight. Odonata in its narrow sense forms a subgroup of the broader Odonatoptera, which contains other dragonfly-like insects. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Biological Resources Study
Australian Biological Resources Study (ABRS) is a project undertaken by the Parks Australia Division of Australia's Department of Climate Change, Energy, the Environment and Water. Background ABRS was founded in 1973 from the recommendations of a 1972 Senate Select Committee report on Wildlife Conservation. ABRS was first set up as an Interim Council in 1973, followed by the establishment of the Study proper in 1978. The main aim of the Interim Council was to stimulate the study of taxonomy, distribution and ecology of Australia's biological resources via research grants, and for assessing the long term national requirements for taxonomic studies and maintenance of national collections of biological specimens. Research grants A core aim of the ABRS is to provide funding to support research on taxonomy and systematics for Australia's biota. The first grants offered by ABRS were to support the collection and scientific description of Australian plants and animals. Up to $75 ...

Robert John Tillyard
Robert "Robin" John Tillyard Fellow of the Royal Society, FRS (31 January 1881 – 13 January 1937) was an English–Australian entomology, entomologist and geologist. Early life and education Tillyard was the son of J. J. Tillyard and his wife Mary Ann Frances, née Wilson and was born at Norwich, Norfolk. He was educated at Dover College and intended to enter the army but was rejected on account of having suffered from rheumatism. He won a scholarship for classics at University of Oxford, Oxford and another for mathematics at University of Cambridge, Cambridge, and decided to go to Queens' College, Cambridge. He graduated senior optime in 1903. He went to Australia in 1904 and was appointed second mathematics and science master at Sydney Grammar School. While working as a science master Tillyard found time to publish extensively on dragonflies. After nine years with Sydney Grammar School, he resigned and undertook a research degree in biology at University of Sydney, Sydney U ...
