Neotype of Argis lar Compared with Argis dentata (Crustacea, Decapoda)

The type specimens of Argis lar were collected in the north Pacific. They are no longer in existence. Specimens identified as A. lar by Rathbun, from the type locality and resembling the original specimens of Owen, are used to set up a neotype. This is done because some authors have assumed that spe...

Description
Summary:The type specimens of Argis lar were collected in the north Pacific. They are no longer in existence. Specimens identified as A. lar by Rathbun, from the type locality and resembling the original specimens of Owen, are used to set up a neotype. This is done because some authors have assumed that specimens of Argis collected in the north Atlantic were A. lar and not A. dentata which they believed was not a valid species. Also the distribution of both species in northern Canadian waters is not yet clearly understood. Outstanding differences between the two species are discussed.
