Glomeridesmida
Glomeridesmida is an order of millipedes in the infraclass Pentazonia containing two families ( Glomeridesmidae and Termitodesmidae) and at least 35 described species. Glomeridesmida is the only living order of the superorder Limacomorpha. Glomeridesmidans are also known as slug millipedes. Description Millipedes in this order are small, usually 4 to 8 mm (0.16 to 0.31 in.) long, with the largest reaching in length. These millipedes are somewhat flattened, and unlike other orders of Pentazonia, are unable to roll into a ball. Glomeridesmidans have antennae with seven segments but are blind and lack ommatidia. The penultimate pair of legs in males are modified into telopods. In most species, females feature a very long ovipositor. Most adult females in this order have 36 pairs of legs and 21 segments, counting 20 tergites plus the anal shield. Male specimens in this order are rare, unknown for all species in the family Termitodesmidae, and known for only a small numbe ...

Glomeridesmidae
Glomeridesmidae is a millipede family of the order Glomeridesmida. This family includes two genera: The genus ''Glomeridesmus'' includes most species in this family; the genus ''Glomeridesmoides'' includes one species. The species in this family are found in Middle America (Americas), Middle and South America, India, Southeast Asia, the East Indies and Oceania. Description In millipedes in this family, the head is visible from above, and the Antenna (biology), antennae are much longer than the head is wide. The first Tergum, tergite (the collum) is smaller than the tergites that follow. The legs are sparesely covered with isolated spines. The female has an elongated ovipositor. Most adult females in this family have 36 pairs of legs and 21 segments, counting 20 tergites plus the anal shield. Male specimens in this family are rare and known for only a few species.

Millipedes
Millipedes (originating from the Latin , "thousand", and , "foot") are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from Latin for "thousand feet", no species was known to have 1,000 or more until the discovery in 2020 of '' Eumillipes persephone'', which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures. Most millipedes are slow-moving detritivores, eating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Termitodesmidae
Termitodesmidae is a family of millipedes belonging to the order Glomeridesmida. These millipedes are found in India, Sri Lanka, and Vietnam. The five known species in this family are notable in that they are found only in termite mounds. Termitodesmidae is the only myriapod family known to depend on insects in such a commensal relationship. Description In millipedes in this family, the head is not visible from above, and the antennae are shorter than the head is wide. The first tergite (the collum) is larger than the tergites that follow. The legs are densely covered with long spines. The female gonopore is a simple vulva without an elongated ovipositor. Males are unknown in this family. Genus and species This family includes only one genus: * '' Termitodesmus'' Silvestri, 1911 This genus contains five species: * '' Termitodesmus calvus'' Attems, 1938 * ''Termitodesmus ceylonicus ''Termitodesmus ceylonicus'' is a species of millipede in the family Glomeridesmidae.

Pentazonia
Pentazonia is a taxonomic infraclass of millipedes containing the pill-millipedes (Oniscomorpha) which can roll into a ball and the order Glomeridesmida which cannot. Defining traits (apomorphies) include divided sternites, a labrum with single median tooth, and an enlarged pygidium on the hind-most body segment. Pentazonia is in the dominant millipede subclass Chilognatha which have a calcified exoskeleton and modified sperm-transferring legs in males. In contrast to the Helminthomorpha Chilognatha is a Subclass (biology), subclass of the Class (biology), class Diplopoda, which includes the vast majority of extant millipede, millipedes, about 12,000 species. Taxonomy The classification of Chilognatha presented below is based on ... – the other Chilognathan infraclass, the sperm-transferring legs are located on posterior body segments and known as ''telopods''. Pentazonians are relatively short-bodied, with between 13 and 21 body segments. The Pentazonia contains one extin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle America (Americas)
Middle America is a subregion in the Northern Hemisphere tropics of the Americas. It usually includes Mexico, the seven countries of Central America, and the 13 island countries and 18 territories of the Caribbean. Together with Northern America, they form the continent of North America. Colombia and Venezuela of Caribbean South America are sometimes included in this subregion. The Caribbean is occasionally excluded from this subregion while The Guianas are infrequently included. Geography Physiographically, Middle America marks the territorial transition between Northern America and South America, connecting yet separating the two.Gonzalez, Joseph. 2004"Middle America: Bridging Two Continents"(ch. 17).

Tropics
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided by precipitation variations than by temperature variations. The tropics maintain wide diversity of local climates, such as rain forests, monsoons, sa ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern Subregion#Americas, subregion of the Americas. South America is bordered on the west by the Pacific Ocean, on the north and east by the Atlantic Ocean, and to the south by the Drake Passage; North America and the Caribbean Sea lie to the northwest. The continent includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territory, dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one administrative division, internal territory: French Guiana. The Dutch Caribbean ABC islands (Leeward Antilles), ABC islands (Aruba, Bonaire, and Curaçao) and Trinidad and Tobago are geologically located on the South-American continental shel ...

Commensalism
Commensalism is a long-term biological interaction (symbiosis) in which members of one species gain benefits while those of the other species neither benefit nor are harmed. This is in contrast with mutualism, in which both organisms benefit from each other; amensalism, where one is harmed while the other is unaffected; and parasitism, where one is harmed and the other benefits. The commensal (the species that benefits from the association) may obtain nutrients, shelter, support, or locomotion from the host species, which is substantially unaffected. The commensal relation is often between a larger host and a smaller commensal; the host organism is unmodified, whereas the commensal species may show great structural adaptation consistent with its habits, as in the remoras that ride attached to sharks and other fishes. Remoras feed on their hosts' fecal matter, while pilot fish feed on the leftovers of their hosts' meals. Numerous birds perch on bodies of large mammal herbivo ...

Myriapoda
Myriapods () are the members of subphylum Myriapoda, containing arthropods such as millipedes and centipedes. The group contains about 13,000 species, all of them terrestrial. Although molecular evidence and similar fossils suggests a diversification in the Cambrian Period, the oldest known fossil record of myriapods dates between the Late Silurian and Early Devonian, with '' Pneumodesmus'' preserving the earliest known evidence of air-breathing on land. Other early myriapod fossil species around the similar time period include '' Kampecaris obanensis'' and '' Archidesmus'' sp. The phylogenetic classification of myriapods is still debated. The scientific study of myriapods is myriapodology, and those who study myriapods are myriapodologists. Anatomy Myriapods have a single pair of antennae and, in most cases, simple eyes. Exceptions are the two classes of symphylans and pauropods, the millipede order Polydesmida and the centipede order Geophilomorpha, which are all ey ...

Termite
Termites are a group of detritivore, detritophagous Eusociality, eusocial cockroaches which consume a variety of Detritus, decaying plant material, generally in the form of wood, Plant litter, leaf litter, and Humus, soil humus. They are distinguished by their moniliform antennae and the soft-bodied, unpigmented worker caste for which they have been commonly termed "white ants"; however, they are not ants but highly Apomorphy and synapomorphy, derived cockroaches. About 2,997 extant species are currently described, 2,125 of which are members of the family Termitidae. Termites comprise the infraorder Isoptera, or alternatively the Taxonomic rank#All ranks, epifamily Termitoidae, within the order Blattodea (the cockroaches). Termites were once classified in a separate Order (biology), order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood-eating cockroaches of t ...
