We redescribe the winged imagos and soldiers of two equatorial African species,
Onagbola EO, Scheffrahn RH (2017) African
The diversity of
Photographs of imagos and soldiers were taken as multi-layer montages using a Leica M205C stereomicroscope controlled by Leica Application Suite version 3 software. Preserved specimens were taken from 85% ethanol and suspended in a pool of Purell® Hand Sanitizer to position the specimens on a transparent Petri dish background. Wings (Fig.
