Differential diagnosis

The females of this species are morphologically similar to those of M. navatu sp. nov., by having the head at least 1.25× as long as wide, and the antennae with 11 flagellomeres. However, M. samburu sp. nov. has the probasisternum large with the anterior margin weakly angulated, whereas M. navatu has the probasisternum markedly large with the anterior margin strongly angulated.

Etymology

The epithet samburu is derived from the Samburu, a semi-nomadic pastoralist of north-central Kenya.
