FIGURE 1 in Description of a new genus and two new species of killifish (Cyprinodontiformes: Nothobranchiidae) from West Africa, with a discussion of the taxonomic status of Aphyosemion maeseni Poll, 1941
FIGURE 1. Distribution map of Archiaphyosemion and Nimbapanchax: A. guineense collections are indicated by a grey circle, N. petersi by a black circle, N. jeanpoli by a grey square, N. viridis by a black square, N. leucopterygius by a grey triangle, and N. melanopterygius by a black triangle. The actual species distribution will in fact be broader based on records not associated with vouchered specimens.

FIGURE 8 in Aphyosemion pamaense, a new killifish species (Cyprinodontiformes: Nothobranchiidae) from Cameroon
FIGURE 8. Consensus tree based on Distance method (Kimura 2 and Neighbor Joining methods), Maximum Likelihood, Minimum Evolution. Numbers above the branches are percentages of bootstrap values based on 2,000 replicates for each method. Numbers correspond to sample location (Figure 1 and Table 1). When more than one sequence were found from the same location, they have been noted a, b. Scale refers to Kimura 2 distance.
