Abstract

In taxonomic studies (in preparation) of the genus Botryllophilus from the eastern and western coastal waters of the Pacific and from the northern Gulf of California, we have found that the females are morphologically divided into 2 types. The 2 morpho-types in our material, which includes 10 species, are characterized by features of the urosome including anal segment and caudal rami, rostrum, antennule, antenna, mandible, maxillule, maxilla, maxilliped, 1st to 5th legs, and the apparatus at the oviducal aperture. These characters are described and the significance of the recognition of the 2 morpho-types is discussed for the purpose of solving taxonomic problems in Botryllophilus.
