Comment | Venomous! Synonymy: Xenocalamus bicolor concavorostralis HOFFMAN 1940 is a synonym of X. b. bicolor fide Bates et al. 2014. The subspecies pernasutus and maculatus are synonyms of bicolor fide Broadley 1971. Type species: Xenocalamus bicolor GÜNTHER 1868 is the type species of the genus Xenocalamus GÜNTHER 1868. Phylogenetics: see Portillo et al. 2018 for a phylogenetic analysis of members of Aparallactinae, inlcuding members of Xenocalamus. Figueroa et al. 2016 synonymized Xenocalamus with Amblyodipsas although they only sampled Xenocalamus transvaalensis, hence we leave Xenocalamus for the time being. Key: Methuen 1919 has a key to the species of Xenocalamus known at the time. |
