Bolton's modern description (1973b) is at
WORKER - TL 7.4-7.6 mm; a very distinctive species, with
unique petiole structure. Few erect hairs but pubescence everywhere
short and yellowish grey in colour (Bolton, 1973b, illustrated,
alitrunk profile, anterior petiole).
Having read Forel's (1911f) description of maynei,
it seems Bolton's synonymy was correct. The latter, however, did not
remark on Forel's point that André had declared the petiole scale had a
flat posterior face and had neither noted the anterior concavity of the
gaster nor its singular form (very elevated - as high as total length,
very short and vertically truncated anteriorly). Forel admitted that he
had not seen curta but felt André could not have missed the
characteristics. Forel also gave TL as 6.2; smaller than the specimens
Bolton described from Ghana.
Only 6-7 other collections, in each case of only a
single worker or female. Collected in Ghana at Bunso (C.A.
Collingwood) and Yakasi (D. Leston), both pkd collections from forested
regions (Bolton, 1973b).

but is a specimen labelled by Bolton as the holotype of "Polyrhachis
bicarinata". It is not clear from the MCZ photographs (there is no
dorsal view) whether there are any pronotal teeth or any margination on
the pronotum, nor it is really clear whether or not there are lateral
teeth on the petiole. No such species is listed in Bolton (1973b) nor
in Bolton's catalogue (1995), so the specimen is an enigma. The nearest
species from the key in Bolton (1973b) is curta, although there
are differences - e.g. the eyes break the outline of the head in full
face view and the yellow appendages. In André's original description
(1890) the colour is given as entirely black, the legs and antennae
brown-black, tibia slightly reddish .
