Leptothorax (Goniothorax) grisoni Forel, 1916: 425 (w.q.). D.R. Congo.

Nesomyrmex grisoni – Bolton 2003: 272 (see also Bolton 1982: 329).

Diagnosis

The following character combination distinguishes N. grisoni from the other species of the group: in profile mesosomal dorsum forming a single, uninterrupted flat surface without any trace of metanotal groove; petiolar peduncle short; body colour dark brown to black.

Diagnostic comments

As mentioned above, N. grisoni and N. angulatus are straightforwardly distinguishable from the remainder of the group. At the same time they are morphologically very close to each other and only separable on the basis of body colour. For a more in-depth discussion we refer to the species account of N. angulatus .

Biology

Very little information about the natural history of this species is available. It seems to live on vegetation in rain forest habitats.

Distribution

Nesomyrmex grisoni is only known from the Central African Republic, the D.R. Congo and Ghana.
