Micro-endemic populations of Palaeocheloctonus Lourenco, 1996 (Scorpiones: Hormuridae) in Madagascar: A new case of vicariance among Malagasy scorpions

摘要

A new scorpion species, Palaeocheloctonus septentrionalis sp.n., is described from the North of Madagascar. The new species clearly suggests a new case of micro-endemic and vicariant population within the island. The number of Palaeocheloctonus species in Madagascar is now increased to two and the known geographical distribution of the genus is extended within that great island, but remains strongly disrupted.
