Miscellaneous Ponerinae

This post previously listed as Pachycondyla is no longer (by the decree of the proclaimed and acclaimed Superlatives experts) of the genus Pachycondyla which has been since 2014 C.E. been redefined to be strictly just Neotropic ants that are to be found no where else except in the Neotropics (relating to or denoting a zoogeographical region comprising Central and South America, including the tropical southern part of Mexico and the Caribbean). Any species resembling by morphology or even genetics of this newly restrictedly redefined genus cannot be and must not be Pachycondyla.

So to obey this decree, all the species in this blog previously classified under Pachycondyla will be redefined as other genera as per this decree. This will be as and when I can find the spare time (redefining still on going).

This post consist of genera of Ponerinae and other subfamilies of ants (previously under the genus Pachycondyla) which have hunter queens. Maybe one day when I have tons of times to spare and nothing better to do, I may redo this post in entirely (instead of a just a cosmetic touch up).

Some of the species (of this location) of the ants in this post are specialist termites hunters. Specialist termite hunters (also includes other arthropods such as centipede) tackle termites differently from other ants that do not specialized on termites. When they encounter termites they kill as many as they can before starting to carry them back to their nest or eat them. They must have 'evolved' this technique to get a higher harvest rate. They also typically stuffed their mandibles with as many as they can carry and not carrying them back one at a time.

Most species are mostly subterranean (at least during the day) and tunneled through the forest soil hunting their preys.

Like Odontoponera, most species of Ponerinae (and also some other subfamily of similar morphology) similarly have 'slippery' feet and the gyne are semi-claustral and hunts for food during the development of her first brood of workers.

Some small species (of the sub tropical region) are currently listed as invasive species and are widely found in the U.S. and known locally as stinging needle ants.

Here then is the decree of the proclaimed and acclaimed Superlative experts on the genus Pachycondyla since redefined, an extract from the Zooxata: The tribal and generic classification of the diverse ant subfamily Ponerinae (Hymenoptera: Formicidae) is revised to reflect recent molecular phylogenetic information and a reappraisal of ponerine morphological diversity. The monogeneric tribe Thaumatomyrmecini (Thaumatomyrmex) is newly synonymized under Ponerini (syn. nov.), and the diverse genus Pachycondyla is fragmented into 19 genera, largely along the lines of its junior synonyms: Bothroponera, Brachyponera (gen. rev.), Ectomomyrmex (gen. rev.), Euponera (gen. rev.), Hagensia (gen. rev.), Megaponera (gen. rev.), Mesoponera (gen. rev.), Neoponera (gen. rev.), Ophthalmopone (gen. rev.), Pachycondyla, Paltothyreus (gen. rev.), Pseudoneoponera (gen. rev.), Pseudoponera (gen. rev.), and 6 new genera: Austroponera (gen. nov.), Buniapone (gen. nov.), Fisheropone (gen. nov.), Mayaponera (gen. nov.), Parvaponera (gen. nov.) and Rasopone (gen. nov.).


The 10 millimeters worker. Ectomomyrmex leeuwenhoeki has really tiny rudimentary eyes. There are several look alike species of around the same size (TL varying from 9 to 11 mm) that looks very similar.

Pachycondyla havilandi worker with larva
Ectomomyrmex leeuwenhoeki  workers with larvae. Ectomomyrmex leeuwenhoeki are among what I called the fat species.


Ectomomyrmex Sp02.
A worker of a small species. This is a much smaller species at 6 mm. It is around half the size of the species listed above.



Ectomomyrmex sp03.
Here is an even smaller species. An alate gyne (5mm) and worker (4.8mm). A drop of 1.2 mm in size may not seem much but in this case the 6 mm species is 25% larger than the 4.8mm species.
 
Workers of one of the smallest species.

Similar to Odontomachus, Odontoponera and Diacamma, The male or drone of this genus looks like wasp. Their antennae are "without" the characteristic elbow.


Mesoponera sp4.
A sleek and polished species. This species of Mesoponera is at 9 mm total length




Brachyponera sp5.

This species resembles the previous species but is only a fraction of its size at slightly over 3 mm.

Workers of a polish and sleek looking species of Brachyponera.


 Brachyponera sp6.
Another small Brachyponera species.
 This species is unique in that the gaster color is different from the body main. It could be an anomaly, possibly infection.

SP14
A large species with workers measuring over 17 millimeters. This species is almost identical to Pseudoneoponera tridentata except for a slight size different of around 2 millimeters. Also the petiole of Pseudoneoponera tridentata is more prominent both broader and higher and having three tiny spines.


Another large species with workers measuring 14 millimeters. This species is a Ectomomyrmex astuta look alike but is significantly larger.



Pseudoneoponera sp(14)
This species resembles Pseudoneoponera tridentata but at around 12 millimeters is significantly smaller.








Buniapone amblyops, a species that look like a cross between ex Pachycondyla and Leptogenys. This species the workers only have rudimentary eyes. This mid size ant hunts both alone and in packs.

Pachycondyla amblyops, a Pachycondyla species that look like a cross between Pachycondyla and Leptogenys.

Measuring around 8 millimeters this monomorphic ant is as effective a solitary hunter as Diacamma and Odontoponera.
