Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development.
In zoological nomenclature, a type species is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). A similar concept is used for suprageneric groups and called a type genus.
Autothysis or suicidal altruism is the process where an animal destroys itself via an internal rupturing or explosion of an organ which ruptures the skin. The term was proposed by Ulrich Maschwitz and Eleonore Maschwitz in 1974 to describe the defensive mechanism of Colobopsis saundersi, a species of ant. It is caused by a contraction of muscles around a large gland that leads to the breaking of the gland wall. Some termites release a sticky secretion by rupturing a gland near the skin of their neck, producing a tar effect in defense against ants.
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 recent study, this species forms a species complex and is probably related to C. explodens, which is part of the C. cylindrica group.
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.
Colobopsis schmitzi, synonym Camponotus schmitzi, is a species of ant native to Borneo, 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.
Globitermes sulphureus is a species of termite that is very common in central and southern Vietnam and also present in other areas of South East Asia, including Cambodia, Thailand, and Peninsular Malaysia. They live in nests made of earth that can be up to 1.5 m tall and can contain tens of thousands of individuals. Between five and 10 per cent of the population are soldier termites which can be recognised by their yellow abdomen and two large, curved mandibles. The termites use autothysis as a defense mechanism.
Camponotini is a tribe containing 2 extinct ant genera and 8 extant ant genera, including Camponotus.

Myrmelachistini is a tribe of ants in the family Formicidae. There are at least 2 genera and 50 described species in Myrmelachistini.
Colobopsis explodens is a species of ant 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.
Lasiini is a tribe of ants in the family Formicidae. There are about 10 genera and more than 450 described species in Lasiini.
Camponotus castaneus, the reddish carpenter ant, is a species of ant in the family Formicidae.
