As this Key develops we shall be concentrating on the more common genera, those with names in caps in the list below. Those where we still have to develop a page appear on the list below in green.
The full list is provided for reference; where further information is available on site the genus name in bold blue CAPS is a link to other pages already on this site.

|www.ispotnature.org/node/629223 [C wissmannii]|
Centromyrmex Four species; obscure, blind yellow/red tropical ponerines with hectic stings
Cerapachys Twelve species; fairly obscure small ponerines, most subtropical
CREMATOGASTER Cocktail ants; 43 species, some are very hard to tell apart
Cryptopone One species; Obscure tiny yellow blind ponerines
Decamorium One species. Slow, timid myrmicine; red brown; mostly Zimbabwe northwards
Diplomorium One species. Obscure, tiny, Monomorium-type ant associated with Messor
Discothyrea Four species. Obscure tiny yellow/red ants that lurk in termite mounds
DORYLUS Driver or Army ants; 12 species. Most can only be told apart by microscopic features.
Euponera Four species. Small [4 - 6 mm] and rare ponerines with tiny eyes
HAGENSIA Three species; handsome large ponerines without the ‘ringbum’ constriction on the first gastral segment
HYPOPONERA Eighteen species; mostly obscure, small ponerines with two invasive tramp species
LEPISIOTA Small black ants; twenty species [one not universally recognised]. One species has become invasive, although indigenous. Minimum 30x magnification needed to tell species apart.
Leptanilla One species; known from a single male specimen [how obscure is that?!]
LEPTOGENYS Rajor-jaw ants; fourteen species. Widespread ponerines.
LINEPITHEMA Argentine ants; one species in Southern Africa. Massively invasive species throughout the temperate regions of Earth.
MEGAPONERA Matabele ants: one species. Large, polymorphic ants famous for their destructive columns and hectic stings
Melissotarsus Two species; rare and small, known only from KZN: there may only be one species, in fact
MERANOPLUS Cautious or Furry ants: seven species. Very hairy, sculpted ants
MESOPONERA Small ringbum ants; three species. Medium to small dull black ponerines
MESSOR Harvester ants; seven species. Medium to large slow-moving polymorphic ants that gather vegetable matter for fungus gardens
Microdaceton Two species; rare, small, KZN and northwards only. Weird little ants with gin-trap jaws
MONOMORIUM Timid ants: 82 species. Widespread, smallish ants; some species are obscure
Nesomyrmex Twenty species; obscure hollow-stem or rotting-wood dwellers, most species with limited distribution and many only recently identified and named
ODONTOMACHUS Troglodyte ants; two species. Large gin-trap-jawed ponerines from KZN northwards; seldom seen

OPHTHALMOPONE Bug-eyed ants; two species. Large, very fast bug-eyed ponerines. Uncommon
PALTOTHYREUS Foul ringbum ants; one species. Huge [>20mm] ants with large jaws that emit foul smells. Widespread but uncommon; some pics are at:
Paretrechina Five species; only known as tramp ants in our region, with records from Durban harbour and South Peninsula High School. Obscure
PHEIDOLE House ants: 25 species. A massive genus world-wide but most local species are small and poorly known, and in something of a taxonomic mess. Pheidole megacephala is an important worldwide invasive species.
Pheidolegeton Three species. Obscure ants, mostly from Namibia; differ from Pheidole in that both majors and minors have huge heads
PLAGIOLEPIS Restless ants; sixteen species. Mostly small and uncommon, they look like small Anoplolepis but are monomorphic.
PLATYTHYREA Beetle-muncher ants; seven species. Medium-sized, slim and fast ponerines that do not really occur in Southern Africa and might eventually be excluded from this site
PLECTROCTENA Millipede muncher ants; three species. Very large ponerines, up to nearly 25mm in length
Prionopelta One species. Tiny and obscure, in forest litter: only one worker ever found in SA, in KZN
Pristomyrmex Two species. Very rare, coarsely-sculpted forest litter ants from KZN
