Distribution: Bolivia, Brazil, Ecuador, Peru. Comments: Reference to Rondani’s type was not possible, as it is not in La Specola Zoology Museum (where most of his collection is) and we have no other clues to its location. However, evidence strongly suggests the

conspecificity of C. podagrica  and P. townsendi  . First, Cresson does not mention P. podagricus  when describing P. townsendi  , suggesting that they were not compared. Also, the paracephalon of P. townsendi  is conspicuously swollen and cannot be used as a differential character as in Hennig (1935). Furthermore, Hennig (1937:49) suggests that P. townsendi  is probably a synonym of C. elegans Hendel  (a synonym of C. podagrica  ). Thus, we here treat P. townsendi  as a synonym of C. podagrica  .
