{Calyptomyrmex clavatus}{Calyptomyrmex clavatus}Weber's (1952) description is at {original description}. Bolton's modern description (1987) is at {original description}

Collected as on card; also known from Ethiopia, at Harrar (collector unknown) and Zare, Yangambi, by M. Maldague (Bolton, 1981a).

Calyptomyrmex clavatusThe photomontage is collated from, where it appears as Calyptomyrmex brunneus, which I think was a misidentification. The postpetiole is slightly larger than the petiole but that is as shown in Bolton's drawing (above).  The anterior clypeal margin does not fit the description for either of the southern African species clavisetus and brunneus.
