Probolomyrmex guineensis Taylor
Type location Guinea
(Taylor, 1965d: 353, illustrated, worker) collected at Nigorie,
Kakoulima, by F. Silvestri, 12.viii.1912
worker only described .
Taylor (1965d) noted that the Guinea record (from
Kakoulima, by F. Silvestri) given by Wheeler (1922) as Probolomyrmex
filiformis was this species. He examined three of the original
seven specimens and described it as a new species -
HL 0.61, HW 0.41, SL 0.38, PW 0.30
Close to filiformis but smaller, with relatively broad head,
short scapes and shorter petiolar node. Sculpturation more distinctive,
shagreening on all body and appendages; head with moderately distinct
puncturation, separated by about the same distance as their diameter
(0.005 mm); alitrunk dorsum with similar puncturation; propodeum with
concave declivity; subpetiolar process without an acute posteroventral
tooth, from above no trace of median emargination on node; colour paler
yellowish or reddish-brown; but with similar all over whitish,
extremely fine adpressed pubescence, most abundant on gaster; very few
erect hairs. Taylor's (1965d) text is at .
Later collected in Ghana, by D Leston, 15 July
1970, at Legon, on ground (in Brown, 1975: 57) and 46 workers, from
leaf litter in the semi-deciduous forest zone - under cocoa at Ofinso
and Kade, under primary forest at Southern Scarp Forest Reserve and
Kade, and under secondary forest at CRIG, by Belshaw & Bolton
(1994b). Brown (1975) also reported specimens from Ivory Coast,
Lamto Research Station, SW of Toumodi (J Lévieux).
Brown (1975) noted there were slight variations in size,
length of the petiole node and in the sharpness of the posteroventral
angle of the subpetiolar process.
Bolton (1973a) listed this as the sole species known
from West Africa, where it nests in small pieces of rotted wood.
