The map does not currently reflect the range of this species

As far as I am aware the sub-species robecchii (recognised from Somalia and probably eastern Ethiopia has not been synonymised with the nominate form.

Yes the map is misleading from the information in the text. In Kenya it occurs from the coast through eastern to northern dryland areas.

Not sure if crepuscular accurately describes this species. I am quite sure it is active during the day...

Yes the species is active only during the day.

In Kenya the species is quite common.

As no Rieppeleon species is listed on CITES, annual CITES export quotas and CITES trade data for this species is lacking. While shipments of pygmy chameleons labeled as R. kerstenii are frequent, this shipments typically contain R. brevicaudatus and R. temporalis, not R. kerstenii. Rieppeleon kerstenii is known to be traded occasionally (one to two shipments every 3-4 years) and in limited to moderate quantities.

No trade in this species in Kenya
