Marasmianympha Eupselias
''Marasmianympha'' is a genus of moths of the grass moth family (Crambidae) described by Eugene G. Munroe in 1991. Its single species, ''Marasmianympha eupselias'', was described by Edward Meyrick in 1929. Among the grass moths, it belongs to subfamily Spilomelinae. It is endemic to the Marquesas Islands of Polynesia, where it has been recorded on Fatu Hiva, Hiva Oa and Tahuata, but is suspected to occur on other islands as well. The holotype specimen is in the Natural History Museum, London. When first described, this moth was assigned to the genus '' Aulacodes'' in subfamily Acentropinae (then known as Nymphulinae). But eventually it was determined that despite a superficial similarity, ''M. eupselias'' is not a member of the Acentropinae, and hence by grass moth standards not at all closely related to ''Aulacodes''. Description and ecology ''M. eupselias'' is a smallish moth with fairly short antennae. It resembles '' Aulacodes'' in having labial palps which do not pro ...

Fatu Hiva
Fatu-Hiva (the "H" is not pronounced, see name section below) is the southernmost island of the Marquesas Islands in French Polynesia, an overseas territory of France in the Pacific Ocean. With Motu Nao as its closest neighbor, it is also the most isolated of the inhabited islands. ''Fatu Hiva'' is also the title of a book by explorer and archaeologist Thor Heyerdahl, in which he describes his stay on the island in the 1930s. Name The name of the island in Marquesan is Fatu Iva (without "h": ). However, the name was recorded by Europeans as ''Fatu-Hiva,'' perhaps under the influence of other Marquesan islands containing the element ''Hiva'' ( Nuku-Hiva and Hiva-Oa) and also because in French the letter "h" is silent. The spelling ''Fatu-Hiva'' has now become official. The island was named ''Isla Magdalena'' ("Magdalene Island") by Spanish explorers in the 16th century, a name rarely used. Hatauheva is another name form that appears in 1817, by Camille de Roquefeuil during h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uncus (insect Anatomy)
The uncus is an anterior extremity of the parahippocampal gyrus. It is separated from the apex of the temporal lobe by a slight fissure called the incisura temporalis (also called rhinal sulcus). Although superficially continuous with the hippocampal gyrus, the uncus forms morphologically a part of the rhinencephalon. An important landmark that crosses the inferior surface of the uncus is the band of Giacomini. The term comes from the Latin word uncus, meaning ''hook'', and it was coined by Félix Vicq-d'Azyr (1748–1794).JC Tamraz, YG Comair. Atlas of Regional Anatomy of the Brain Using MRI (2006), p 8. Clinical significance The part of the olfactory cortex that is on the temporal lobe covers the area of the uncus, which leads into the two significant clinical aspects of the uncus: uncinate fits and uncal herniations. * Seizures, often preceded by hallucinations of disagreeable odors, often originate in the uncus. * In situations of tumor, hemorrhage, or edema, increased ...

Clasper
In biology, a clasper is a male anatomical structure found in some groups of animals, used in mating. Male cartilaginous fish have claspers formed from the posterior portion of their pelvic fin which serve to channel semen into the female's cloaca during mating. The act of mating in some fish including sharks usually includes one of the claspers raised to allow water into the siphon through a specific orifice. The clasper is then inserted into the cloaca, where it opens like an umbrella to anchor its position. The siphon then begins to contract, expelling water and sperm. The claspers of many shark species have spines or hooks, which may hold them in place during copulation. Male chimaeras have cephalic claspers (tenacula) on their heads, which are thought to aid in holding the female during mating. In entomology, it is a structure in male insects that is used to hold the female during copulation (see Lepidoptera genitalia for more). See also *Sexual coercion among animals ...

Lepidoptera Genitalia
The study of the genitalia of Lepidoptera is important for Lepidoptera taxonomy in addition to development, anatomy and natural history. The genitalia are complex and provide the basis for species discrimination in most families and also in family identification. The genitalia are attached onto the tenth or most distal segment of the abdomen. Lepidoptera have some of the most complex genital structures in the insect groups with a wide variety of complex spines, setae, scales and tufts in males, claspers of different shapes and different modifications of the ductus bursae in females. The arrangement of genitalia is important in the courtship and mating as they prevent cross-specific mating and hybridisation. The uniqueness of genitalia of a species led to the use of the morphological study of genitalia as one of the most important keys in taxonomic identification of taxa below family level. With the advent of DNA analysis, the study of genitalia has now become just one of the te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palp
Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and anterior to the first pair of walking legs. Overview Pedipalps are composed of six segments or articles: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus. In spiders, the coxae frequently have extensions called maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior legs. The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders, or chelate weapons ( pincers) of great size, as in scorpions. The pedipalps of Solifugae are covered in setae, but have not been studied in detail. Comparative studies of pedipalpal morphology may suggest that leg-like pedipalps are primitive in arachnids. At present, the on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched ...

Nymphulinae
Acentropinae is a fairly small subfamily of the lepidopteran family Crambidae, the crambid snout moths. Species of this subfamily are exclusively found in wetlands and aquatic habitats. Systematics In modern treatments, the former subfamily Nymphulinae is mostly treated as a tribe within Acentropinae. There are about 730 species in 78 genera. Only 13 species in 6 genera are found in Europe. *'' Acentria'' Stephens, 1829 (= ''Acentropus'' J.

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the large ''Diplodocus'' cast that domina ...
