We resurrect Dipsadoboa guineensis from the synonymy of D. brevirostris and consider the latter species a junior synonym of D. duchesnei. In addition we resurrrect Philothamnus pobeguini and P. belli from the synonymy of P. heterodermus. 19 species were not previously collected in this country, including Letheobia coecata, Tricheilostoma bicolor, Myriopholis rouxestevae, Rhinoleptus koniagui, Python regius, Grayia tholloni, Natriciteres fuliginoides, Philothamnus heterolepidotus, Thrasops aethiopissa, Amblyodipsas unicolor, Gonionotophis granti, Mehelya crossi, Prosymna gregeirti, Prosymna meleagris, Rhamphiophis oxyrhynchus, Elapsoidea trapei, Naja katiensis, Naja senegalensis and Echis jogeri. Based on a critical review of literature and our own data, we compare the currently known snake fauna of Guinea (104 species) with that of Sierra Leone (65 species), Liberia (63 species), Ivory Coast (101 species), Ghana (102 species), Togo (93 species), Benin (72 species) and Nigeria (118 species). specialized taxonomy biogeography Guinea West Africa Dipsadoboa guineensis Philothamnus belli Philothamnus pobeguini Echis jogeri AFRIQUE DE L'OUEST GUINEE SIERRA LEONE LIBERIA COTE D'IVOIRE GHANA TOGO BENIN NIGERIA 080 082 3900 3 301-338 2014 1175-5326 https://www.documentation.ird.fr/hor/PAR00012794 1175-5326 [F B010063667] https://www.documentation.ird.fr/hor/PAR00012794 https://www.documentation.ird.fr/intranet/publi/2015/02/010063667.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-03-03 2017-08-23 PAR00012794 fre
