|Comment||Morphological differentiation between congestus, liberiensis and punctatus is minor but they inhabit different habitats: savannah (punctatus), forest (congestus and liberiensis) according to BRANCH & RÖDEL 2003.|
“According to Roux-Estève (1974), there are no clear morphological criteria for distinguishing the forest (sub)species A. liberiensis from the savanna (sub)species A. punctatus, except a lower number of mid-dorsal scales for A. liberiensis (26–32) compared to A. punctatus (30–34), the arrangement of subocular/preocular, and a longer maximum and average length for A. liberiensis as compared to A. punctatus. Our 19 specimens from rainforest areas of Guinea have 26 (4 specimens), 28 (11) or 30 (3) mid-dorsal scales, compared to 30 (24) or 32 (4) mid-dorsal scales for the 28 specimens from savanna areas of Guinea that we attribute to A. punctatus. The maximum length was 950 mm for a A. liberiensis female from Konipara (IRD 2669.G, a record size for the species), compared to 592 mm for a A. punctatus female from Kalékouré. Our preliminary molecular data also support the recognition of A. liberiensis as a distinct species. Both marbled and lineated patterns were represented.” (from TRAPE & BALDÉ 2014)
