Synthemiopsis
''Synthemiopsis gomphomacromioides'', also known as the Tasmanian spotwing, is a species of dragonfly from southern and north-western Tasmania, Australia. It is the only species in the genus ''Synthemiopsis'' and has also been placed in its own tribe, Synthemiopsini. R. J. Tillyard, who first described it, considered it intermediate between the Australian genus ''Synthemis'' and the Chilean '' Gomphomacromia''. He had material from swamps around Cradle Mountain, at about altitude, and from Flowerdale Creek near Wynyard. ''Synthemiopsis gomphomacromioides'' flies rapidly over the swamps and often sits on reeds. It occurs together with '' Synthemis tasmanica'', a similar but duller-coloured species. Documentation Tillyard described ''Synthemiopsis gomphomacromioides'' in 1917 on the basis of both adults and larvae, but his larvae are in fact probably '' Synthemis tasmanica'', a different dragonfly species. Arthropod researcher Günther Theischinger documented the larvae of '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthemistidae
The Synthemistidae are the family of dragonflies commonly known as tigertails, or sometimes called southern emeralds. This family is sometimes treated as a subfamily of Corduliidae. This is an ancient dragonfly family, with some species occurring in Australia and New Guinea. Most species are small in size and have narrow abdomens. Their nymphs are bottom dwellers, and resist droughts by burying themselves very deeply. Synthemistid dragonflies frequently prefer marshy areas, as well as fast-flowing streams. The family Synthemistidae is sometimes called Synthemidae. Genera The family Synthemistidae includes the following genera: * ''Apocordulia'' * '' Archaeophya'' * '' Archaeosynthemis'' * ''Austrocordulia'' * ''Austrophya'' * '' Austrosynthemis'' * '' Choristhemis'' * ''Cordulephya'' * '' Eusynthemis'' * '' Gomphomacromia'' * ''Hesperocordulia'' * '' Idionyx'' * '' Idomacromia'' * ''Lathrocordulia'' * '' Lauromacromia'' * '' Macromidia'' * ''Micromidia'' * '' ...

Robert John Tillyard
Robert "Robin" John Tillyard FRS (31 January 1881 – 13 January 1937) was an English–Australian 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 Oxford and another for mathematics at 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 Sydney University and took his research BSc degree in 1914. Career He was seriously injured in a railway acciden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal ...

Appendages
An appendage (or outgrowth) is an external body part, or natural prolongation, that protrudes from an organism's body. In arthropods, an appendage refers to any of the homologous body parts that may extend from a body segment, including antennae, mouthparts (including mandibles, maxillae and maxillipeds), gills, locomotor legs (pereiopods for walking, and pleopods for swimming), sexual organs (gonopods), and parts of the tail (uropods). Typically, each body segment carries one pair of appendages. An appendage which is modified to assist in feeding is known as a maxilliped or gnathopod. In vertebrates, an appendage can refer to a locomotor part such as a tail, fins on a fish, limbs (legs, flippers or wings) on a tetrapod; exposed sex organ; defensive parts such as horns and antlers; or sensory organs such as auricles, proboscis ( trunk and snout) and barbels. Appendages may become ''uniramous'', as in insects and centipedes, where each appendage comprises a single series ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lobe (anatomy)
In anatomy, a lobe is a clear anatomical division or extension of an organ (as seen for example in the brain, lung, liver, or kidney) that can be determined without the use of a microscope at the gross anatomy level. This is in contrast to the much smaller lobule, which is a clear division only visible under the microscope. Interlobar ducts connect lobes and interlobular ducts connect lobules. Examples of lobes *The four main lobes of the brain **the frontal lobe **the parietal lobe **the occipital lobe **the temporal lobe *The three lobes of the human cerebellum **the flocculonodular lobe **the anterior lobe **the posterior lobe *The two lobes of the thymus *The two and three lobes of the lungs ** Left lung: superior and inferior ** Right lung: superior, middle, and inferior *The four lobes of the liver ** Left lobe of liver ** Right lobe of liver ** Quadrate lobe of liver ** Caudate lobe of liver *The renal lobes of the kidney * Earlobes Examples of lobules *the c ...

Postocular
In scaled reptiles, the ocular scales are those forming the margin of the eye.Wright AH, Wright AA. 1957. ''Handbook of Snakes''. Comstock Publishing Associates (7th printing, 1985). 1105 pp. . The name originates from the term ''oculus'' which is Latin for 'eye' and, in the broadest sense, refers to a scale associated with the eye. The numbers of these scales present, and sometimes the shapes and sizes, are some of many characteristics used to differentiate species from one another. Prefixes are usually included to indicate the positions or locations of the individual scales:Mallow D, Ludwig D, Nilson G. 2003. ''True Vipers: Natural History and Toxinology of Old World Vipers''.

Lateral (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of ana ...

Frontal Bone
The frontal bone is a bone in the human skull. The bone consists of two portions.'' Gray's Anatomy'' (1918) These are the vertically oriented squamous part, and the horizontally oriented orbital part, making up the bony part of the forehead, part of the bony orbital cavity holding the eye, and part of the bony part of the nose respectively. The name comes from the Latin word ''frons'' (meaning " forehead"). Structure of the frontal bone The frontal bone is made up of two main parts. These are the squamous part, and the orbital part. The squamous part marks the vertical, flat, and also the biggest part, and the main region of the forehead. The orbital part is the horizontal and second biggest region of the frontal bone. It enters into the formation of the roofs of the orbital and nasal cavities. Sometimes a third part is included as the nasal part of the frontal bone, and sometimes this is included with the squamous part. The nasal part is between the brow ridges, and ends ...

Setae
In biology, setae (singular seta ; from the Latin word for " bristle") are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. Crustaceans have mechano- and chemosensory setae. Setae are especially present on the mouthparts of crustaceans and can also be found on grooming limbs. In some cases, setae are modified into scale like structures. Setae on the legs of krill and other small crustaceans help them to gather phytoplankton. It captures them and all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ligula
In the brain, the taenia of the fourth ventricle (lingula, tenia of fourth ventricle) are two narrow bands of white matter, one on either side, which complete the lower part of the roof of the fourth ventricle. Each consists of a vertical and a horizontal part. * The ''vertical part'' is continuous below the obex with the gracile nucleus, to which it is adherent by its lateral border. * The ''horizontal portion'' extends transversely across the inferior peduncle, below the striae medullares, and roofs in the lower and posterior part of the lateral recess; it is attached by its lower margin to the inferior peduncle, and partly encloses the choroid plexus, which, however, projects beyond it like a cluster of grapes; and hence this part of the tænia has been termed the ''cornucopia''.
