Constrictotermes
Constrictotermes is a genus of Neotropical higher termites within the subfamily Nasutitermitinae. They form large open-air foraging columns from which they travel to and from their sources of food, similar to the Indomalayan species of processionary termites. Species of this genus commonly build epigeal or arboreal nests and feed on a variety of lichens, rotted woods and mosses. Description Soldiers are monomorphic and identifiable with a notable constriction of the head behind the antenna sockets; the antenna have 13-14 articles, and the points of the mandibles are small. Species of this genus are distributed throughout the Neotropics, occurring primarily within South America and Central America; with one species, ''C. guantanamensis,'' being found within the extreme southeastern coast of Cuba. Within South America, Constrictotermes spp. can be found from the tropical rainforests of the Amazon to the xeric shrublands of Northeastern Brazil. As with all Nasutitermitinae ter ...

Constrictotermes Cavifrons
''Constrictotermes cavifrons'' is a species of Amazon rainforest, Amazonian Nasutitermitinae, nasute termite within the genus ''Constrictotermes''. It forms large and diurnal open-foraging trails to and from its sources of food which consists largely of lichens and other Micro-epiphyte, microepiphytes. The nests of ''C. cavifrons'' are arboreal and characterized by a cleared central runway from which foraging raids begin. Description The soldiers have antennae with 13 – 14 articles (antennomeres) and the length of the head ranges between 1.25 – 1.50 mm. The head and abdomen segments are pigmented dark in contrast to the conspicuously yellowish thorax, matching the coloration of workers. Soldiers of this species molt from sclerotized worker-like forms which are slightly smaller than the actual workers but otherwise appear to behave no differently. The head of the presoldier form measures between 0.839 – 0.887 mm while workers range between 0.936 – 1.036 mm. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constrictotermes Cyphergaster
''Constrictotermes cyphergaster'' is a Neotropical species of open-air foraging nasute termite within the genus ''Constrictotermes''. This species is distributed widely throughout South America and lives within xeric habitats such as the savannas found in Paraguay, Bolivia, Central Brazil, and Northern Argentina. ''C. cyphergaster'' primarily builds arboreal and transient epigeic nests and mainly consumes dead woods at varying stages of decomposition. Description Biology Nests of ''C. cyphergaster'' are mostly arboreal and are typically found between 0.4 and 3 meters high on a host tree. The nests vary between a reddish brown and grayish brown in color, are oval and the texture of the surface is reticulated. Growth and proliferation of nests coincides with seasonal changes. Most of the new small nests that emerge during the wet season are satellite colonies, which is associated with increased seasonal polycalism within ''C. cyphergaster''. In the Caatinga region of Brazil, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nasutitermitinae
The Nasutitermitinae is a near Cosmopolitan distribution, cosmopolitan subfamily of Termitidae, higher termites represented by 81 genera and 605 species. The highly derived soldier caste exhibits vestigial mandibles and a protruding Fontanellar gun, fontanellar process on the head, known as the nasus, from which they can "shoot" chemical weaponry. Notable genera include the notorious wood-eating Nasutitermes, and the conspicuous Hospitalitermes and Constrictotermes, both distinguished for their brazen habit of forming extensive foraging trails exposed to the open. Genera The ''Termite Catalogue''Termite Catalogue (retrieved 7 July 2019)/ref> lists the following: References External links Tree of Life (TolWeb) * * {{Taxonbar, from=Q15213827 Termites ...

Hospitalitermes
''Hospitalitermes'' is an Asian–Papuan genus of lichen-eating termite in the subfamily Nasutitermitinae. There are 37 species currently listed, of which most are recognized for their extensive surface foraging columns. Due to their conspicuous foraging activities, they are commonly known as processionary or marching termites. They often inhabit cavities inside of living trees excavated by other species of termite. Description The length of the workers and soldiers is about 5 mm. As with other genera in the subfamily, soldiers have a nasal tube from which, in case of danger, they shoot terpene-based repellents. They are one of the few species and genera of termites (''Hospitalitermes'', along with '' Lacessititermes'' and '' Longipeditermes'') that forage in large columns in the open air. In the species ''Hospitalitermes hospitalis'', the width of the columns is 20–30 mm (up to 8 termites in a row), they move away from the nest by an average of 29 m (up to 65 m), visi ...

Insects Of South America
Insects (from Latin ') are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. The ...

Nils Holmgren
Nils Frithiof Holmgren (September 28, 1877 – September 7, 1954) was a Swedish zoologist and comparative anatomist. He was professor of zoology at Stockholm University from 1921 to 1944. He took a special interest in the taxonomy of termites. Holmgren went to the Stockholm University College and in 1906 he defended his doctoral dissertation at the newly created Stockholm University. In 1912 he became a teacher at the zoological institute, and in 1919 assistant professor of zoology (replacing Wilhelm Leche), and in 1921 full professor. His early work focussed on the biology, systematics and anatomy of insects, especially termites, as in (1906) and (1909–1912). In later work he focused on the structure of the brain in worms, arthropods and vertebrates, publishing (1916) (Comparative anatomy of the brain), (1919), (1920), ''Points of view concerning forebrain morphology in lower vertebrates'' (1922), (with C. J. van der Horst) ''Contribution to the morphology of the brain' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotropical Realm
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropics, tropical Ecoregion#Terrestrial, terrestrial ecoregions of the Americas and the entire South American temperate climate, temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean Islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Phytochorion, Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic Floristic Kingdom, Antarctic kingdom. The Neo ...
