Issue
Authorship controversial, but follows Rosa (1985a) in crediting original species name to Müller & Henle and not to d’Orbigny. Species later redescribed by Müller & Henle (1841) based on five additional specimens, but these do not have type status (the action of Castex, 1969, in designating a lectotype is therefore not valid; Rosa, 1985a). May be confused in the literature with P. orbignyi (occurrences in French Guiana, Guyana, Suriname, Venezuela). Reproductive biology unknown. Additional references: Bertin (1939), Castex (1965); Achenbach & Achenbach (1976), Compagno & Cook (1995).
