Asphinctopone differens Bolton & FisherHNS sp. n.

(Figs 1c,d; 2b,d)

Holotype worker. TL 3.7, HL 0.82, HW 0.66, CI 81, SL 0.61, SI 92, PW 0.48, WL 1.06. Answering the description of silvestriiHNS, above, but differing as follows.

Side of propodeum entirely densely irregularly sculptured.

Dorsum of propodeum with a pelt of fine short pubescence that is erect and weakly curved.

In addition, pubescence on the pronotum and mesonotum is more dense and more elevated than in silvestriiHNS. The propodeal dorsum in profile is longer and flatter than in any silvestriiHNS specimen examined, but the latter shows variation in the shape of the propodeum, and as only a single specimen of differensHNS is known it is impossible to tell if the sclerite also shows variation here. In differensHNS the dorsal margin of the anepisternum is distinctly concave, whereas in all known silvestriiHNS specimens it is flat to very feebly sinuate.

Holotype worker, Central African Republic: P.N. Dzanga-Ndoki, 37.9 km. 169°S Lidjombo, 2°22'N, 16°10'E, 360 m., 21.v.2001, #4130(30), CASENT 0417143, sifted litter, rainforest (B.L. Fisher) (CASC).

The two species are obviously very closely related. We infer they are two distinct species because (1) specimens of silvestriiHNS are known from the type-locality of differensHNS and thus occur in sympatry and (2) the differences between the single specimen of differensHNS and all the observed material of silvestriiHNS are distinct for multiple non-overlapping characters
