Tyrannomyrmex Dux
''Tyrannomyrmex'' is a rare tropical genus of ants in the subfamily Myrmicinae. Three similar species, only known from workers, are recognized and share small eyes and edentate mandibles. Species Two of the species are known only from single worker specimens, but a single male specimen collected in 1965 possibly represents the male of an otherwise unknown species, and ''T. alii'' is known from a series of over 35 gynes and workers. So far, all species of ''Tyrannomyrmex'' occur in tropical Old World forests. The wide distribution range from India and Sri Lanka in the west to peninsular Malaysia and perhaps the Philippine archipelago in the east suggests that more species may be discovered. * '' Tyrannomyrmex alii'' Sadasivan & Kripakaran, 2017 - Western Ghats, India * '' Tyrannomyrmex dux'' Borowiec, 2007 – Kerala, India * '' Tyrannomyrmex legatus'' Alpert, 2013 – Sinharaja Forest Reserve, Sri Lanka * '' Tyrannomyrmex rex'' Fernández, 2003 – Negri Sem ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...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 ...

Ommatidia
The compound eyes of arthropods like insects, crustaceans and millipedes are composed of units called ommatidia (singular: ommatidium). An ommatidium contains a cluster of photoreceptor cells surrounded by support cells and pigment cells. The outer part of the ommatidium is overlaid with a transparent cornea. Each ommatidium is innervated by one axon bundle (usually consisting of 6–9 axons, depending on the number of rhabdomeres) and provides the brain with one picture element. The brain forms an image from these independent picture elements. The number of ommatidia in the eye depends upon the type of arthropod and range from as low as 5 as in the Antarctic isopod ''Glyptonotus antarcticus'', or a handful in the primitive Zygentoma, to around 30,000 in larger Anisoptera dragonflies and some Sphingidae moths. Description Ommatidia are typically hexagonal in cross-section and approximately ten times longer than wide. The diameter is largest at the surface, tapering toward the in ...

Monomorium
''Monomorium'' is a genus of ants in the subfamily Myrmicinae. As of 2013 it contains about 396 species. It is distributed around the world, with many species native to the Old World tropics. It is considered to be "one of the more important groups of ants," considering its widespread distribution, its diversity, and its variety of morphological and biological characteristics. It also includes several familiar pest species, such as the pharaoh ant (''M. pharaonis'') and the flower ant (''M. floricola''). Description This genus is very diverse in morphology, with species of many shapes and sizes that "do not necessarily even remotely resemble one another" at first glance. While the worker caste is monomorphic in some species, in others it is polymorphic. In some species the workers are minute, in others they are rather large. Large, multifaceted eyes are common, but ''M. inusuale'' has much reduced eyes, as do some species from Africa. The sting is always functional.Fernández, ...

Adelomyrmex
''Adelomyrmex'' is a genus of ants in the subfamily Myrmicinae. Species of ''Adelomyrmex'' are small, litter-inhabiting ants most often collected in Berlese and Winkler samples. Although the genus and its relatives have a pantropical distribution, Central American cloud forests are the only places where they are abundant and diverse. Habitat and distribution The center of ''Adelomyrmex'' abundance and diversity is Central America, and a few far-flung species occur in New Guinea, Samoa, Fiji, Tonga, New Caledonia, and Isla del Coco. Several ''Adelomyrmex'' species are mountain-top endemics with very restricted ranges, and climate change clearly poses the threat of mountain-top extinction. The geographic range of the genus in the New World is (1) the mainland from northern Mexico to Amazonian Brazil; (2) the Galápagos, where the mainland species ''A. myops'' is probably recently introduced; and (3) Isla del Coco, a small oceanic island north of the Galápagos, with a hig ...

Dipterocarp Forest
Dipterocarpaceae is a family of 16 genera and about 695 known species of mainly tropical lowland rainforest trees. The family name, from the type genus ''Dipterocarpus'', is derived from Greek (''di'' = two, ''pteron'' = wing and ''karpos'' = fruit) and refers to the two-winged fruit. The largest genera are ''Shorea'' (196 species), ''Hopea'' (104 species), ''Dipterocarpus'' (70 species), and ''Vatica'' (65 species).Ashton, P.S. Dipterocarpaceae. In ''Tree Flora of Sabah and Sarawak,'' Volume 5, 2004. Soepadmo, E., Saw, L. G. and Chung, R. C. K. eds. Government of Malaysia, Kuala Lumpur, Malaysia. Many are large forest-emergent species, typically reaching heights of 40–70 m, some even over 80 m (in the genera ''Dryobalanops'', ''Hopea'' and ''Shorea''), with the tallest known living specimen (''Shorea faguetiana'') 93.0 m tall. The species of this family are of major importance in the timber trade. Their distribution is pantropical, from northern South America to Africa, the Sey ...

Lowland
Upland and lowland are conditional descriptions of a plain based on elevation above sea level. In studies of the ecology of freshwater rivers, habitats are classified as upland or lowland. Definitions Upland and lowland are portions of plain that are conditionally categorized by their elevation above the sea level. Lowlands are usually no higher than , while uplands are somewhere around to . On unusual occasions, certain lowlands such as the Caspian Depression lie below sea level. Upland habitats are cold, clear and rocky whose rivers are fast-flowing in mountainous areas; lowland habitats are warm with slow-flowing rivers found in relatively flat lowland areas, with water that is frequently colored by sediment and organic matter. These classifications overlap with the geological definitions of "upland" and "lowland". In geology an "upland" is generally considered to be land that is at a higher elevation than the alluvial plain or stream terrace, which are considered ...

Incertae Sedis
' () or ''problematica'' is a term used for a taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty at specific taxonomic levels is indicated by ' (of uncertain family), ' (of uncertain suborder), ' (of uncertain order) and similar terms. Examples *The fossil plant '' Paradinandra suecica'' could not be assigned to any family, but was placed ''incertae sedis'' within the order Ericales when described in 2001. * The fossil ''Gluteus minimus'', described in 1975, could not be assigned to any known animal phylum. The genus is therefore ''incertae sedis'' within the kingdom Animalia. * While it was unclear to which order the New World vultures (family Cathartidae) should be assigned, they were placed in Aves ''incertae sedis''. It was later agreed to place them in a separate order, Cathartiformes. * Bocage's longbill, ''Motacilla bocagii' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
