Strumigenys transenna

Identification
Bolton (2000) - S. transenna is the largest Afrotropical species yet recorded in the genus. It is close to Strumigenys londianensis and Strumigenys sarissa, also from East Africa. S. londianensis is easily isolated as it possesses some hairs on the leading edge of the scape that are curved toward the base of the scape, and the pronotal humeral hairs are remiform and stiff. In the other two species all hairs on the leading edge of the scape are curved toward the apex of the scape and the humeral hairs are long and flagellate. S. sarissa is decidedly smaller than transenna (compare measurements) and has a pair of erect stiff hairs anteriorly on the pronotal dorsum, between the flagellate hairs at the humeri.
