Confirmed observations

A single sighting recorded west of Cotonou in 2013 (Zwart and Weir, 2014). This sighting is also described in Van Waerebeek et al. (2017) and its close proximity to the sightings in Togo, as well as the homogeneity of the Togo-Benin coastline suggests that cross border movements are possible.
