(Polyrhachis sulcata nov. sp.,
André, 1895a: 1, queen; Bolton, 1973b: 322, worker) collected by
Albert Mocquerys, in the Ogooué Delta (not Brazzaville, as cited

 André's (1895a) description
of the queen is at  . Bolton's modern
description (1973b) is at  .
WORKER - TL 7.8-9.2 mm; unique sculpturation of very
deep
regularly spaced striae, areas between them strongly convex so as to
give a ploughed appearance. Off-white to yellowish white erect hairs
present on all surfaces of the body and appendages. Little pubescence.
Colour black with apices of appendages lighter, often yellow or dull
yellow-brown (Bolton, 1973b, illustrated, dorsal view of full body,
alitrunk and petiole profile, anterior petiole).
Wheeler (1922) listed it from Cameroun (by H.
Brauns).
Others from Ghana, at Kade and Bunso, by pkd (D.
Leston) (Bolton, 1973b). Purely speculatively, this could be the
species named as Polyrhachis species near militaris by
Majer (1976b), with four workers in a single sample at Kade. It is
pictured in Hölldobler & Wilson (1990, page 140; but the labelling
is transposed between the two species of Polyrhachis, the lower
being sulcata).
Rigato (2016) added: EQUATORIAL GUINEA, Bioko, Moka, 1300 m, 3°21’36” N 8°39’49”E, 1–11.x.1998 at lights (D. Ubick, D.K. Dabney, R.C. Drewes, J.V. Vindum, L. Henwood, R.W. Tomos, M. Boko, M.P. Ndung) (3 g, CAS).
