Polyrhachis Lamellidens
''Polyrhachis'' is a genus of formicine ants found in the Old World with over 600 species. The genus is yet to be comprehensively resolved and contains many varied species including nest-weavers (e.g. ''Polyrhachis dives''), swimming workers (e.g. ''Polyrhachis sokolova''), soil (e.g. ''Polyrhachis proxima'') and tree-dwellers (e.g. ''Polyrhachis bicolor''). The first fossil record of this genus was of '' Polyrhachis annosa'' from the Miocene. General morphology Size: Workers range in size approx 5–10mm in length. Eyes developed, no ocelli. Antennae have 12 segments. Antennal insertions situated far from posterior margin of clypeus. Mesosoma of most species have spines on one or more of its pronotal, mesonotal or propodeal components. Petiole armed with spines or teeth. First gastral tergite well developed, longer in dorsal view than exposed parts of the following terga together. Opening at gastral apex for release of venom lacking a radial fringe of hairs. Ecology ''Polyrha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyrhachis Gracilior
''Polyrhachis gracilior'' is a species of ant Ants are Eusociality, eusocial insects of the Family (biology), family Formicidae and, along with the related wasps and bees, belong to the Taxonomy (biology), order Hymenoptera. Ants evolved from Vespoidea, vespoid wasp ancestors in the Cre ... found in the southwest and northeast India. It is one of the few ants that build arboreal nests made of leaves stitched together using silk produced by their larvae. Originally described as a "race" of '' Polyrhachis furcata'', it was elevated to a full species by C T Bingham who noted differences in the shape of the spines. A species described from Travancore as ''weberi'' by Horace Donisthorpe in 1943, was identified as being identical to ''gracilior'' by Barry Bolton.

Subgenera
In biology, a subgenus ( subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', a sub ...

Camponotus Quadrinotatus
Carpenter ants (''Camponotus'' spp.) are a genus of large ants (workers ) indigenous to many parts of the world. True carpenter ants build nests inside wood, consisting of galleries chewed out with their mandibles or jaws, preferably in dead, damp wood. However, unlike termites, they do not consume wood, but instead discard a material that resembles sawdust outside their nest. Sometimes, carpenter ants hollow out sections of trees. They also commonly infest wooden buildings and structures, causing a widespread problem: they are a major cause of structural damage. Nevertheless, their ability to excavate wood helps in forest decomposition. The genus includes over 1,000 species. They also farm aphids. In their farming, the ants protect the aphids from predators (usually other insects) while they excrete a sugary fluid called honeydew, which the ants get by stroking the aphids with their antennae.
