Status Mortensen (1948: p. 233) list Phaleropygus de Loriol, 1902 as possible synonym of Studeria Duncan, 1889. In the Echinoid Directory it is listed as possible synonym of Gitolampas Gauthier, 1889 or Rhopostoma Cooke, 1959. A re-description of the type-species is necessary to solve this question. [details]
