A Review of the Cornetfishes, Genus Fistularia (Fistulariidae), with a Discussion of Intrageneric Relationships and Zoogeography
Abstract:The cornetfishes, genus Fistularia, are found worldwide in tropical seas. There are four extant species, F. tabacaria, F. commersonii (= petimba, auctorum), F. corneta, and F. petimba (= villosa, auctorum). They form two species pairs.
F. tabacaria is found throughout the tropical Atlantic. Its closest relative, F. commersonii, is distributed across the Pacific and Indian Oceans. The distribution of these two species shows a typical tethyan pattern.
The remaining two species, F. petimba and F. corneta, form the other species pair. F. petimba is found throughout the tropical Atlantic and Indo-West Pacific Oceans. F. corneta is restricted to the tropical eastern Pacific. It is inferred that the ancestor of this species group was unable to cross the East Pacific Barrier.
