Camponotus (Tanemyrmex) occasus majorThe photomontage is of a major worker from Senegal, Tambacounda, collector B Ndiaye.

The dull, or opaque, surface of the head and alitrunk is as described by Emery

If my diagnosis is correct this is the first record from mainland Africa. The Cape Verde Islands, however, are situated some 500 km west of Dakar, the prinicipal port of Senegal.  thus the finding of the species in Senegal is not over surprising.
