Roger's (1859, 1860) description is at . Charsley's (1877) description of Ponera tarda is at . Forel's (1892l) description of jugata is at . Emery (1909c: 373) gave an illustrated description, this is at . Santschi (1921e) gave an illustrated description, this is at . Santschi (1923a) gave a further note, with a naming of exacta, this is at . He accepted that the length of the scape varied between populations and was often shorter than in his (1921e) drawing, which he said was of exacta.

Bernard's key (1952, now probably incorrect) has it as - TL 2.5-3.0, head large, with convex sides; clypeus and thorax matt, dull red; mandibles with 5 large, spaced out, teeth.

Collingwood (1985, illustrated), reporting it from Saudi Arabia, noted that the frontal furrow on the face continues as a thin line.

Seifert (2003b: 61ff - http://antbase.org/ants/publications/21154/21154.pdf) reported an analytical study of specimens previously identified as Hypoponera punctatissima or varieties. This led him to separate off Hypoponera schauinslandi (Emery) as a distinct sibling species, type location Hawaii,with an African synonym aemula, formerly Ponera dulcis var. aemula Santschi, type location Tanzania. Also Hypoponera indifferens Forel (1895), type location Madagascar. (Forel, 1895c: 245, worker & queen). Seifert gave a review of the habitat requirements of punctatisssima and schauinslandi in Europe north of 40° latitude. This strongly suggests punctatisssima is endogenous to temperate Europe, i.e. tolerant of relatively cool, dry climates. H. schauinslandi is found only in hothouse situations in Europe, with air temperatures constantly above 19°C (usually between 22°C and 27°C) and appears to have its origins in the humid tropics. Thus Seifert characterized the latter as a "tropical, cosmopolitan, tramp species".

My feeling, therefore, is that the reports of H. punctatissima from sub-Saharan Africa, including my own from Nigeria, are very likely to be of H. schauinslandi.

Seifert (2003b) unfortunately chose to use a set of different measurements, or at least to use different names for the measurements. Thus -
CL = maximum cephalic length in median line (i.e similar to HL but taken from the lowest point of any concavity of the occipital margin to the upper clypeal prtrusion
CW = maximum cephalic width, i.e = HW
CS = cephalic index, arithmetic mean of CL and CW
Eyepos = difference between a posterior reference point, apparently where a transverse line from the eye centres transect the median longitudinal line of the head

Nigeria specimens (as Hypoponera punctatissina, Taylor, 1976: 21). WORKER. TL 2.46 mm, HL 0.58, HW 0.47, SL 0.39, PW 0.34
Seifert measurements: CS = 525 CL/CW 123 SL/CS = 0.742)
Colour dark yellow-brown, shiny with dense pilosity. Eyes absent. Metanotal groove distinct.
I collected it from in an old tree stump, in dead wood and in soil, some 5-7 cm deep, the Cocoa Research Institute of Nigeria, Idi Ayunre.

The photomontage is of a worker from Gabon, Pongara National Park; collector Yves Braet (Gabon 194).

The photomontage is of a worker from Cameroun, Awae II; collector A Fotso Kuate.

. Previously listed by me as H. brevis

The photomontage is of a queen from Central African Republic, Dzanga-Sangha NP; collector Philippe Annoyer.

A similar queen from Mauritius can be seen at http://www.antweb.org/specimen.do?name=casent0055829
