First record of Ozolaimus cirratus (Oxyuroidea: Pharyngodonidae) infecting the casque-headed tree frog Corythomantis greeningi (Anura: Hylidae) from Northeast Brazil

The genus Ozolaimus is characterised by presenting a dorsoventrally elongated mouth with two lateral lips, a very long oesophagus consisting of anterior portion strong and short, with a fusiform fold, and a thin posterior portion ending in a distinct bulb, an anteriorly dilated intestine, and absent...

Description
Summary:The genus Ozolaimus is characterised by presenting a dorsoventrally elongated mouth with two lateral lips, a very long oesophagus consisting of anterior portion strong and short, with a fusiform fold, and a thin posterior portion ending in a distinct bulb, an anteriorly dilated intestine, and absent lateral wings. Between February 2014 and September 2016, 11 specimens of the anuran Corythomantis greeningi were collected manually at the Ecological Station of Aiuaba, Ceará State, Brazil. After analysis, nine specimens of Ozolaimus cirratus infecting the large intestine of the referred specimen were recorded. Knowledge is still scarce about the ecological dynamics of pharyngodonid parasites and their parasitehost relationships; thus, this work is the first to record members of the genus Ozolaimus infecting the casqueheaded tree frog Corythomantis greeningi from the Caatinga biome. Previously, the only registered hosts of Ozalaimus parasites were iguanid lizards.
