Redescription of Mesokalliapseudes crassus (Menzies, 1953) (Crustacea: Tanaidacea: Kalliapseudidae): The First Record of a Hermaphroditic Kalliapseudid
Coastal Sciences, Gulf Coast Research Laboratory
The type species of the genus Mesokalliapseudes Lang 1956, M. crassus (Menzies 1953), which was originally incompletely described and illustrated, is redescribed and a key to the species of the genus is provided. A study of type and non-type material indicates that M. crassus is a protandric hermaphrodite. All of the adult specimens of M. crassus examined, including presumptive males and preincubatory and incubatory females, had a male genital cone. In all other aspects, except for the development of oostegites in the female phase, this species expresses no marked sexual dimorphism.
