Colobopsis
''Colobopsis'' is a genus of ant in the subfamily Formicinae. This genus was first described in 1861 by Mayr and contains 95 species. The type species is '' Colobopsis truncata''. Description As part of Camponotini, ''Colobopsis'' workers have distinctive mandibular dentition (5-8 teeth with the 3rd tooth from the apex not being reduced), antennae 12-segmented and antennal separations well separated from the posterior clypeal margin. ''Colobopsis'' workers are dimorphic, being divided into major workers and minor workers. The major workers generally have phragmotic heads that are truncate to varying extents. This may cause them to be confused for '' Camponotus'' and vice versa, since some ''Camponotus'' also have phragmotic heads. Pupae of ''Colobopsis'' are always naked. This is unlike pupae of ''Camponotus'', which are enclosed in cocoons. Phylogeny For a period of time, ''Colobopsis'' was considered a subgenus of ''Camponotus''. A 2015 phylogenomic study found it to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colobopsis Explodens
''Colobopsis explodens'' (suicidal attack ants) is a species of ant Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22 ... which is found in Southeast Asia. It is noted for a rare combat mechanism of workers exploding in self-defense, smothering the enemy with toxic and often deadly secretion. Defenses The species was formerly known informally as "yellow goo", named after the brightly colored gunk produced by its exploding worker ants. Territory Their colonies can contain thousands of individual ants and inhabit the leafy canopies of trees that stand as tall as and cover an area of at least .

Colobopsis Anderseni
''Colobopsis anderseni'', synonym ''Camponotus anderseni'', is a species of mangrove ant found in northern Australia. Taxonomy The species was originally placed in the ant genus '' Camponotus'' when described in 2001 as ''Camponotus (Colobopsis) anderseni''. In a revision of the ant subfamily Formicinae published in 2016 the subgenus ''C. (Colobopsis)'' found to be phylogenetically distinct from the other subgenera for ''Componotus''. As a result, the subgenus was raised to full genus status as ''Colobopsis'', with the species moved out of ''Camponotus'', resulting in the new binomial ''Colobopsis anderseni''. Description ''Colobopsis anderseni'' is light brown and glossy. Like any insect, its body contains three sections. The first part is called the prosoma while the middle part is called the mesosoma, and the posterior part is called the metasoma. The dorsum, or posterior side, of the mesosoma on ''C. anderseni'' is flattened. It also has distinct metanotum on the posteri ...

Colobopsis Saundersi
''Colobopsis saundersi'', synonym ''Camponotus saundersi'', is a species of ant found in Malaysia and Brunei, belonging to the genus ''Colobopsis''. A worker can explode suicidally and aggressively as an ultimate act of defense, an ability it has in common with several other species in this genus and a few other insects. The ant has an enormously enlarged mandibular (jaw) gland, many times the size of a normal ant, which produces defense adhesive secretions. According to a 2018 study, this species forms a species complex and is probably related to '' C. explodens'', which is part of the '' C. cylindrica'' group. Defenses Its defensive behaviours include self-destruction by autothysis, a term coined by Maschwitz and Maschwitz (1974). Two oversized, poison-filled mandibular glands run the entire length of the ant's body. When combat takes a turn for the worse, the worker ant violently contracts its abdominal muscles to rupture its gaster at the intersegmental fold, which also bur ...

Colobopsis Schmitzi
''Colobopsis schmitzi'', synonym ''Camponotus schmitzi'', is a species of ant native to Borneo, Schuitemaker, J.P. & A. Stärcke 1933. ''Overdruk uit het Natuurhistorisch Maandblad'' 22(3): 29–31. which is commonly known as the diving ant, swimming ant or pitcher-plant ant, due to their habit of diving into the digestive fluids of their plant host ''Nepenthes bicalcarata''. They are endemic to the island of Borneo. Description ''C. schmitzi'' closely resemble '' Colobopsis ceylonicus'' but are slightly larger. They have rectangular heads about one and a half times as long as they are wide. The mandibles have five teeth each (except for the minor workers which have four). The eyes are widely separated and located laterally, slightly behind the anterior bulge of the head. The antennae are short, with a scape at in length. The funicules are longer than they are wide proximally and become shorter and wider towards the tip. The body is smooth and shiny. The gaster is small. The l ...

''Colobopsis abdita'' (synonym ''Camponotus abditus'') is a species of carpenter ant endemic to Guatemala Guatemala ( ; ), officially the Republic of Guatemala ( es, República de Guatemala, links=no), is a country in Central America. It is bordered to the north and west by Mexico; to the northeast by Belize and the Caribbean; to the east by H .... It was described by Forel in 1899. Based on specimen collections, ''C. abditus'' ants are found in montane rainforest edge habitats, at elevations of 1,140 metres (3,740 ft). This species is rather small.

Formicinae
The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development. Formicines retain some primitive features, such as the presence of cocoons around pupae, the presence of ocelli in workers, and little tendency toward reduction of palp or antennal segmentation in most species, except subterranean groups. Extreme modification of mandibles is rare, except in the genera ''Myrmoteras'' and ''Polyergus''. However, some members show considerable evolutionary advancement in behaviors such as slave-making and symbiosis with root-feeding hemipterans. Finally, all formicines have very reduced stings and enlarged venom reservoirs, with the venom gland, specialized (uniquely among ants) for the production of formic acid. All members of the Formicinae "have a one-segmented petiole in the form of a vertical scale". Identification Formicine ants have a single node-like or scale-like petiole (postpetiole entirely lacking) and the apex of the abdom ...

Phragmosis
Phragmosis is any method by which an animal defends itself in its burrow, by using its own body as a barrier. This term was originally coined by W.M. Wheeler (1927), while describing the defensive technique exhibited by insects. Wheeler observed the positioning of specially modified body structures to block nest entrances, as exhibited in various insect species. The term phragmosis has since been further extended beyond just insects. Examples of phragmosis are found in the order Anura (frogs and toads). Some species, such as ''Pternohyla fodiens'' and ''Corythomantis greeningi'', have evolved a peculiarly casqued head adapted to protect the animal as it backs down a hole. Another example is the head-plug defense used by the aphid ''Astegopteryx'' sp., in which a banana-bunch shaped gall consisting of several subgalls is used as a barrier. Arguably, the most commonly observed phragmotic behaviour is within the ant family. The behaviour is displayed in numerous taxa such as '' Campon ...
