Comment | Synonymy: Dipsadoboa isolepis is listed as valid species in LeBreton 1999 and mentioned as such by TRAPE & ROUX-ESTÈVE 1995: 41. Distribution: not in Liberia fide TRAPE & BALDÉ 2014: 320. For a map with localities in Equatorial Guinea see SÁNCHEZ-VIALAS et al. 2022. Populations from Togo and further west have been described as D. riparia, as announced by Trape & Baldé 2014: “We provisionaly attribute these specimens D. cf. weileiri, although they clearly represent an undescribed species. They differ from typical D. weileiri from Cameroon, Gabon and Congo both by habitat (savanna for all our specimens, central African rainforest block for D. weileri) and colouration in life (dorsum green versus blackish respectively) and in preservative (underside of the tail whitish or pale blue grey versus blackish respectively). In life, the supralabials of our specimens were bright yellow, the belly pale yellow, and the underside of the tail pale yellow or pale greenish. However, we were unable to find clear meristic differences between this undescribed species and D. weileri.” (TRAPE & BALDÉ 2014) |
Etymology | Named after J. Weiler, who collected reptiles in Tanganyika (now Tanzania) and Cameroon, and gave the collection to Lorenz Müller. |
