Strumigenys dyshaula

Identification
Of the species possessing a preocular notch and relativelly large eyes a number of forms do not have the preocular notch extended onto the ventral surface of the head as a transverse impression. Among the six species in this category Strumigenys dyshaula is distinguished by having a postpetiole whose sides are not completely lapped around by spongiform tissue, having the ventral lobe of the postpetiole well developed, having six standing hairs on the cephalic dorsum and having basigastral costulae which do not arise as a regular row across the width of the tergite but rather radiate out from each side of a central clear area.

Distribution
This taxon was described from Zimbabwe. It is also found in Tanzania.
