Syntermitinae
The Syntermitinae is a neotropical subfamily of mandibulate nasute termites in the family Termitidae which contains 18 genera and 101 species. Majority of members in this subfamily have a soldier caste with a conspicuous horn-like projection from the fontanelle on their head adapted for chemical defense, similar to the fontanellar nasus of true nasute termites. However unlike true nasutes, the soldiers' mandibles are highly developed and they are unable to expel their chemical weaponry at a distance, relying instead on direct physical contact. Some genera, such as Syntermes, have completely lost their nasus. Both ''Nasutitermitinae'' and ''Syntermitinae'' are not closely related, with Syntermitinae being more closely related to either the ''Amitermes-group'' or '' Microcerotermes'' ''Termitinae''. Identification The frontal-gland aperture of soldiers is at the tip of a large projection (nasus) located in the frontal region of the head and the soldier mandibles have a recognizab ...

Rhynchotermes
Rhynchotermes is a genus of neotropical higher termites within the subfamily Syntermitinae, represented by 8 known species. Species of this genus are known for their soldiers which have highly developed, curved mandibles and a pronounced frontal tube superficially analogous to the fontanellar guns of true nasute termites. Most species forage above the surface in the open where they primarily feed on forest leaf litter. Nests are subterranean or are shallow and epigeic. Description Worker, Soldier and Imago have antennae with 14 articles (antennomeres) with the first and third articles longer than the second. Soldiers are smaller than workers, are either monomorphic or dimorphic and the head capsule is rounded to a near pear shape. The inner margins of the mandibles are either serrated or smooth, strongly or evenly curved and the inner marginal tooth is conical. Apical extent of mandibles either weakly overlapping or evenly distanced when closed. The frontal tube about the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syntermes
''Syntermes'' is a genus of large, hornless, open foraging Syntermitinae termites belonging to the family Termitidae Termitidae is the largest family of termites whose members are commonly known as the higher termites. They are evolutionarily the most specialised termite group, with their highly compartmentalized hindgut lacking the flagellated protozoans comm .... The genus is most recognized for the large mounds built from loose soil that some species construct, with some as old as 4,000 years.

Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate 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 the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

Termitidae
Termitidae is the largest family of termites whose members are commonly known as the higher termites. They are evolutionarily the most specialised termite group, with their highly compartmentalized hindgut lacking the flagellated protozoans common to "lower termites". Whereas lower termites are restricted mostly to woody tissue, higher termites have diverse diets consisting of wood, grass, leaf litter, fungi, lichen, faeces, humus and soil. Subfamilies The family contains the following subfamilies: *Termitidae Latreille, 1802 **Subfamily Apicotermitinae Grassé & Noirot, 1954 955/small> (synonym: Indotermitidae Roonwal & Sen Sarma in Roonwal, 1958) **Subfamily Cubitermitinae Weidner, 1956 **Subfamily Foraminitermitinae Holmgren, 1912 (synonym: Pseudomicrotermitinae Holmgren, 1912) **Subfamily Macrotermitinae Kemner, 1934, nomen protectum CZN 2003/small> (synonyms: Acanthotermitinae Sjöstedt, 1926, nomen rejiciendum CZN 2003/small>; Odontotermitini Weidner, 1956 **Subfamily ...

Neotropical Realm
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American 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 Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
