Description of four new species of Oswaldocruzia
parasitizing Iguanidae and Leptodactylidae from Ecuador,
demonstrate that they are morphologically close to each other.
Like most of the other neotropical and holarctic
Oswaldocruzia, they are characterized by spicules with
three main branches: blade, shoe and fork; the division of the
fork within the distal third of the spicule length appears to be
characteristic of the neotropical species.
