TYPE LOCALITY.— Unknown taxonomic identity (see comments) .

DISTRIBUTION.— Members of the Arthroleptis poecilonotus species complex are widely distributed, ranging from Guinea-Bissau to Uganda, and southwards to Gabon, Congo and Central African Republic. In Equatorial Guinea, it has been recorded both in Río Muni at Cabo San Juan ( Boulenger 1900, 1903), Monte Alén ( De la Riva 1994) and in several localities on Bioko ( Mertens 1965; Hydeman et al. 2017) ( Map 2C ).

COMMENTS.— See comments on A. adelphus .

Phylogenetic evidence suggests that under the name A. poecilonotus Peters, 1863 there is a species complex comprising multiple allopatric species from (1) Western Ghana and Sierra Leone, (2) Togo Hills of Eastern Ghana, (3) Cameroon, and (4) Bioko ( Blackburn 2008) . The lineage identified from Bioko by Blackburn (2008) was formally described as A. bioko ( Blackburn 2010) . Arthroleptis poecilonotus has two available synonyms, A. macrodactylus Boulenger, 1882 described from Gabon and A. inguinalis Boulenger, 1900 described from Benito River ( Equatorial Guinea). As the type locality of A. poecilonotus is in Ghana (Holländischen Besitzungen (Boutry) [ Ghana] an der Küste von Guinea), the different lineage from Cameroon, and also, the unstudied populations from Gabon and Equatorial Guinea deserve other nomenclatural denominations once an exhaustive taxonomic revision is made.
