Available name. Type specimen: Unknown to us. Type locality:Cayenne ’ ( Castelnau, 1840 ). Nomenclatural history: To our knowledge, this name was first mentioned as a synonym of C. lancifer by Lacordaire(1856) , who cited that as males of this species; this opinion was followed by all subsequent revisers and cataloguers ( Nevinson, 1892 ; Gillet, 1911 ; d’Olsoufieff, 1924 ; Pessôa, 1934 ; Blackwelder, 1944 ; Edmonds & Zídek, 2010 ). No syntypes of this name were found by us and, therefore, a lectotype designation is not possible at the moment. See the discussion on P. sylvanus for more details.
