2.1 Sampling
We obtained 20 specimens of Toxicodryas (seven T.
blandingii and 13 T. pulverulenta ) through fieldwork and from
various museums (see Table S1). Sampling was representative of the known
range of each species throughout the upper and lower Guinean forest
blocks of West and Central Africa including the countries of Guinea,
Liberia, Ghana, Cameroon, Gabon, and Democratic Republic of the Congo
(DRC). Museum catalog numbers, GenBank accession numbers, and locality
data for each specimen are presented in Table S1.
