Red Driver Ant (Male)

Male driver ants, sometimes known as "sausage flies" (a term also applied to males of New World ecitonines) due to their bloated, sausage-like abdomens, are the largest known ants, and were originally believed to be members of a different species. Males leave the colony soon after hatching, but are drawn to the scent trail left by a column of siafu once it reaches sexual maturity. When a colony of driver ants encounters a male, they tear its wings off and carry it back to the nest to be mated with a virgin queen. As with all ants, the males die shortly afterward.[2]
Such is the strength of the ant's jaws that in East Africa they are used as natural, emergency sutures. Various East African indigenous tribal peoples (e.g. Maasai moran), when suffering from a gash in the bush, will use the soldiers to stitch the wound by getting the ants to bite on both sides of the gash, then breaking off the body. This use of ants as makeshift surgical staples creates a seal that can hold for days at a time, and the procedure can be repeated if necessary, allowing natural healing to commence.[4][5] http://en.wikipedia.org/wiki/Dorylus

Very interesting insect! It looks like some type of wasp to me. It could be a species of Horntail, Family Siricidae. I am not absolutely sure.
