DISTRIBUTION .— This species inhabits the forests of southern Nigeria and Cameroon . In Equatorial Guinea , it is only recorded from Bioko ( Hydeman et al. 2017 ) ( Map 9A ).

However, an integrative approach is necessary to test if this insular lineage is part of the geographically structured intraspecific variability or a different species. SPECIMENS EXAMINED .— One specimen . Moka, Bioko, 03°20ʹ23.47ʺN , 08°40ʹ6.20ʺE , 15 November 2003 ( MNCN 50377 ) .
