  Anergates - Wikipedia, the free encyclopedia
Anergates Forel, 1874 is a single-species genus of tetramorine Myrmicine ants.
It is a worker-less obligate parasite to Tetramorium caespitum, the "lawn ant" or "pavement ant", and is thought to have evolved as an aberrant form of the genus Tetramorium.
Since, unlike many other obligate social parasites, Anergates is never known to coexist with the host colony's fertile queen, every Anergates-Tetramorium colony is doomed to survive only the lifespan of the youngest Tetramorium workers.

 Informaton On Worker-Less Parasites. - www.ezboard.com
The phylogenetic relationships among Palaearctic species of the independent ant genus Tetramorium and its social parasites of the genera Strongylognathus, Anergates and Teleutomyrmex, were investigated electrophoretically at 21 presumptive enzyme loci.
Anergates atratulus and Teleutomyrmex schneideri could nonetheless be more distant to their hosts than is the rule in many other parasitic ants.
Under this scenario, morphological and behavioural peculiarities in Anergates and Teleutomyrmex would not represent cases of adaptive convergence, known as the 'inquiline syndrome'.

Since, unlike many other obligate social parasites, Anergates is never known to coexist with the host colony'sfertile queen, every Anergates-Tetramorium colony is doomed to survive only the lifespan of the youngestTetramorium workers.
Thus, the parasitic queen has very limited scope for producing alates to secure the nextgeneration, as this time span is often only 2-3 years or fewer.

 Anergates (GW60) - www.ezboard.com
The genus Anergates was described in 1874 by A. Forel to house the species Myrmica atratula, described by C. Schenck in 1852.
Most think now that the host queen is already dead before the inquiline enters the colony.The Anergates queen " must be " to weak to kill the host queen.
It is by Crawley (1912) and it is the observation of the killing of a Tetramorium queen by her workers when an Anergates queen is present.

These sexuals mate with each other in their home nest, the females, now queens leave the nest and find a colony of a different but particular species of ant.
On finding a suitable nest she enters it, kills the ruling queen and uses her workers to raise her own sexuals, she produces no workers of her own, this is called 'social parasitism' the only British example is Anergates atratulus which is a social parasite on Tetramorium caespitum.
To ants such as the South American Army ants which have no permanent nest sites, but travel around the forest eating anything they can get their mandibles on and making temporary bivouacs out of their workers bodies whenever the make a short rest at any particular site, i.e.

It has no workers of its own,only queens and curiously shaped,wingless males.
The Anergates queens enter the host nest,with little,or no opposition;they just walk in.
These queens are then fed by the Tetra.workers and they lay many eggs;all of which produce more sexuals and no workers of their own.

Now, the situation is much improved with many excellent generic and subgeneric revisions stemming from the work of Bolton, as follows:
Bolton (1976) gave definitive Tetramoriine genera as Anergates Forel, Decamorium Forel, Rhoptromyrmex Mayr (incorporating Acidomyrmex and Ireneella), Strongylognathus Mayr (incorporating Myrmus), Teleutomyrmex Kutter, Tetramorium Mayr (incorporating Tetrogmus, Xiphomyrmex, Atopula, Macromischoides, subgenus Lobomyrmex and subgenus Sulcomyrmex) and Triglyphothrix Forel.
In the same paper he revised the last genus and provided keys for Decamorium and Rhoptromyrmex.

Abstract - New data on tetramoriine ants in southern Italy are presented, based on recent collections from Sardinia, Sicily, Calabria, Apulia and Abruzzi.
Numerous records of the socially parasitic genera Strongylognathus and Anergates lead to significant extensions of the known range for several species.
