The systematics and reproductive biology of the Galeus arae subspecific complex (Chondrichthyes : Scyliorhinidae)

2000 
Galeus arae is currently classified as a complex of three subspecies (Galeus arae arae, Galeus arae antillensis, and Galeus arae cadenati). Morphometric and meristic analyses, size at maturity, and variation in color patterns, support the recognition of these taxa as distinct species. All species have well-developed nidamental glands and are oviparous. Galeus arae comprises two geographically disjunct populations that are not distinguishable by the characters we examined. A northern population occurs along the east and Gulf coasts of North America from South Carolina to the Mississippi delta, and the northern coast of Cuba to the north-eastern tip of the Yucatan. A southern population occurs along the Caribbean coasts of Honduras, Nicaragua, and Costa Rica, and some neighboring islands. Galeus antillensis occurs on the northern coasts of Hispaniola and Puerto Rico, and off many of the Leeward Islands. Galeus cadenati occurs off the Caribbean coasts of Panama and Colombia. Distributional data suggest that the three species are distributed allopatrically.
