Haaniella Glaber
''Haaniella'' is a genus of the Phasmatodea family Heteropterygidae from Southeast Asia. Characteristics The species of the genus ''Haaniella'' reach a body length of 4.5 to 16.5 cm in the female sex. The males, which are 2.5 to 9.8 cm in length, are always smaller and have a slimmer abdomen than the females, whose abdomen, especially in the middle, is wider than the rest of the body. In females, as in all members of the subfamily Heteropteryginae, the abdomen ends in a secondary ovipositor, which surrounds the actual ovipositor. The fore wings (tegmina) of the adult females only just reach the abdomen. They also end at this height in the males of most species. Only the wings of males of '' Haaniella aculeata'', ''Haaniella glaber'' and ''Haaniella mecheli'' are significantly longer and have a similar wing construction as those of ''Heteropteryx dilatata''. Their narrow fore wings cover half or part of almost the entire abdomen. The hind wings below are usually even lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Endemic
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karim ...

Sternite
The sternum (pl. "sterna") is the ventral portion of a segment of an arthropod thorax or abdomen. In insects, the sterna are usually single, large sclerites, and external. However, they can sometimes be divided in two or more, in which case the subunits are called sternites, and may also be modified on the terminal abdominal segments so as to form part of the functional genitalia, in which case they are frequently reduced in size and development, and may become internalized and/or membranous. For a detailed explanation of the terminology, see Kinorhynchs have tergal and sternal plates too, though seemingly not homologous with those of arthropods.Sørensen, M. V. et al. Phylogeny of Kinorhyncha based on morphology and two molecular loci. PLoS One 10, 1–33 (2015). Ventrites are externally visible sternites. Usually the first sternite is covered up, so that vertrite numbers do not correspond to sternid numbers. The term is also used in other arthropod groups such as crustaceans ...

Arthropod Coxa
The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) are of Latin origin, and may be confused with terms for bones: ''coxa'' (meaning hip, plural ''coxae''), ''trochanter'', ''femur'' (plural ''femora''), ''tibia'' (plural ''tibiae''), ''tarsus'' (plural ''tarsi''), ''ischium'' (plural ''ischia''), ''metatarsus'', ''carpus'', ''dactylus'' (meaning finger), ''patella'' (plural ''patellae''). Homologies of leg segments between groups are difficult to prove and are the source of much argument. Some authors posit up to eleven segments per leg for the most recent common ancestor of extant arthropods but modern arthropods have eight or fewer. It has been argued that the ancestral leg need not have been so complex, and that other events, such as successive loss of function of a ''Hox''-gene, could result in parallel gains of leg segments. In arthropods, each of the leg segments artic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haaniella Scabra
''Haaniella scabra'' is a species of stick insect native to Borneo and a typical representative of the subfamily Heteropteryginae. The occasionally used common name Small Haaniella refers to the size of this. Description ''Haaniella scabra'' primarily differs from most of the other representatives of the genus by its much smaller size. Many sharp spines can also be found in this species on the head, body and legs of both sexes. The formation of the wings also corresponds to that of the other '' Haaniella'' species. Both pairs of wings are shortened, with the forewings, which are designed as tegmina, completely covering the hindwings, which have been transformed into stridulation organs. The males are only long. The abdomen and legs are usually dark brown in color. The head and thorax are drawn somewhat livelier due to lighter parts. The spines in particular are usually very light or almost white. The forewings at rest reveal an equally bright "V"-shaped pattern. The remaining w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haaniella Saussurei
''Haaniella saussurei'' is a species of stick insect native to Borneo and a typical representative of the subfamily Heteropteryginae. The occasionally used common name Saussure's Haaniella refers to the species name. Description As is typical for most of the species of the genus '' Haaniella'', both sexes of ''Haaniella saussurei'' have many sharp thorns on the body and legs and very short wings. The front wings, which are designed as tegmina, completely cover the short hind wings (alae). The latter are transformed into stridulation organs and are used to ward off enemies. The females are often patterned in contrasting light and dark brown, but can also only be dark. With increasing age, the contrast in the patterned females decreases and the animals become darker. Egg-laying females have a conspicuously plump abdomen, the end of which is formed by a spike-like laying apparatus that surrounds the actual ovipositor. The dorsal end segment of this ovipositor is formed by the eleve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haaniella Grayii
''Haaniella grayii'' is a stick insect species native to Borneo. It is a typical representative of the subfamily Heteropteryginae and the largest species of the genus '' Haaniella''. The occasionally used common name Gray's Haaniella refers to the species name. Description ''Haaniella grayii'' has the genus-typical sharp spines distributed over the body and legs in both sexes. Also typical of the genus are the strongly shortened forewings, developed as tegmina, which completely cover the short hindwings, which have been transformed into stridulation organs. The slimmer males, which have much more spines on their backs and are more colorful, remain smaller at than the females, which are long. In addition to almost monochromatic beige-brown, more rarely brown to black-brown females, there are also specimens with high-contrast light and dark brown patterns, which can have light, almost white patterns on the mesonotum, the front wings and the abdomen. They usually get a little da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haaniella Dehaanii
''Haaniella dehaanii'' is a stick insect species. It is a typical representative of the subfamily Heteropteryginae. The occasionally used common name De Haan's haaniella refers to the species name. Description Both sexes, like all species of this genus, have many pointed spines on their bodies and legs. The shortened tegmina has developed front wings completely cover the just as shortened hind wings. Females are dark brown in color and very compact in shape. The abdomen of egg-laying specimens in particular bulge in shape. The abdomen ends in a spike-like secondary ovipositor. Characteristic is a triangular or oval area in front of the wings, which is white to beige in the otherwise black-brown female nymph and only light brown to beige in the adult, then-brown females. In contrast to the top, the bottom is very vividly drawn. Female nymphs in particular have bright orange areas on the undersides of the femura, the meso- and metathorax, the intermediate membranes of the abdomin ...

Borneo
Borneo (; id, Kalimantan) is the third-largest island in the world and the largest in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, and east of Sumatra. The island is politically divided among three countries: Malaysia and Brunei in the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory. In the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The population in Borneo is 23,053,723 (2020 national censuses). Additionally, the Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. The sovereign state of Brunei, located on the north coast, comprises about 1% of Borneo's land area. A little more than half of the island is in the Northern Hemisphere, including Brunei and the Malaysian portion, while the Indonesian portion spans the Northern and Southern hemisph ...
