Polyergus Oligergus
''Polyergus'' is a small genus of ants with 14 described species. They are also referred to by the names "Slave-raiding ants" or "Amazon ants". They are characterized by their habit of raiding nests (of Formica) for workers. Reproduction ''Polyergus'' workers are incapable of caring for brood, for the most part due to their dagger-like, piercing mandibles. As such, they have evolved to rely on certain species of ants in the genus ''Formica''. They have lost the instinct for carrying out even rudimentary brood care, and even for feeding themselves (which they are unable to do). ''Polyergus'' 'workers' exist more as a force of improvised soldiers, acting in essence solely to raid the ''Formica'' nests. The captured ants are generally referred to as "slaves" in scientific and popular literature, though recent attempts have been made to apply other human cultural models. Some of these describe the ''Polyergus'' as "raiders", "pirates", or "kidnappers". They also describe the ''Form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyergus Breviceps
''Polyergus breviceps'' is a species of ant endemic to the United States. It is a social parasite of other ants, namely of '' Formica gnava'' but also of ''Formica occulta'' and '' Formica argentea''. ''Polyergus'' is an inquiline parasite, having lost its ability to take care of its young and themselves. "The workers do not forage for food, feed the young or the queen, or even clean up their own nest". To survive, ''Polyergus'' workers raid ''Formica'' nests to steal the pupae—which, once hatched, become workers of the mixed nest. This sort of relationship is not unique, of the approximately 8,800 species of ants, at least 200 have evolved some form of symbiotic relationship with one another. What makes ''Polyergus'' special is the way a newly mated queen can, all by herself, take over a ''Formica'' nest and start a new colony. Slave raids and colony takeovers ''Polyergus'' workers emerge from their nest (a mixed nest where ''Formica'' workers are already enslaved) and forage ...

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 ...

Incertae Sedis
' () or ''problematica'' is a term used for a taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty at specific taxonomic levels is indicated by ' (of uncertain family), ' (of uncertain suborder), ' (of uncertain order) and similar terms. Examples *The fossil plant '' Paradinandra suecica'' could not be assigned to any family, but was placed ''incertae sedis'' within the order Ericales when described in 2001. * The fossil ''Gluteus minimus'', described in 1975, could not be assigned to any known animal phylum. The genus is therefore ''incertae sedis'' within the kingdom Animalia. * While it was unclear to which order the New World vultures (family Cathartidae) should be assigned, they were placed in Aves ''incertae sedis''. It was later agreed to place them in a separate order, Cathartiformes. * Bocage's longbill, ''Motacilla bocagii' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyergus Samurai
''Polyergus samurai'' is a species of slave-making ant in the subfamily Formicinae. Distribution It was long thought endemic to Japan, but is now also known from Korea and northeastern China.''Купянская А. Н.'' 1990. Муравьи Дальнего Востока СССР. – Владивосток: ДВО АН СССР. – 258 с. (с.209–210) Description The queen and workers of this slave-maker ant species are black or dark brown in color (unlike the more western species) generally matching the host species in color. Behavior Like other species of the genus, it is a parasite to host ''Formica'' ant species. The colony begins when a young queen leaves her parent colony and mates. The queen then searches for a suitable host colony. When the ''P. samurai'' queen invades the host ''Formica japonica'' colony, she kills the resident ''Formica'' queen or queens and adopts the colony's scent. She then takes the role as queen, laying eggs destined to become her firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polyergus Mexicanus
''Polyergus mexicanus'' is a species of slave-making ant in the subfamily Formicinae. It is the most widely distributed species of ''Polyergus'' in North America. It is an obligatory social parasite, unable to feed itself or look after the colony and reliant on ants of another species, ''Formica'', to undertake these tasks. The parasitic ants are known as "dulotics" (from the Greek δοῦλος ''doulos'', meaning a slave) and the ants they parasitise are known as "hosts". Taxonomy In a revision of the genus ''Polyergus'' in 2013, Trager reinstated five species previously thought to be synonymous with ''Polyergus breviceps''. ''P. mexicanus'' was one of these, a widely distributed species found in western North American and originally described by the Swiss myrmecologist Auguste Forel in 1899, the type locality being Mexico. It is likely that most species mentioned in scientific journals as ''P. breviceps'' are in fact ''P. mexicanus''. Description ''P. mexicanus'' is somewha ...
