Numerous taxa show ancient intertropical disjunct distributions. Many can be explained by well-known processes of historical vicariance, such as the breakup of Gondwanaland. Others, such as Asian–Neotropical divergences are not as well understood. To clarify the phylogenetic position and understand biogeographic and temporal origins the geographically disjunct and morphologically unique genera of hinged-teeth snakes, Scaphiodontophis (n = 1) and Sibynophis (n = 9; Colubridae), we inferred a time-calibrated phylogeny with additional 107 taxa representing the...
