A new species of temnocephalan is described from the branchial chambers of Valdivia serrata in Colombia as Temnocephala ivandarioi sp. nov. The most distinctive characters of the new species are in the cirrus and the epidermal ‘excretory’ syncytial plates. In the present study, the terminology to describe the cirrus of species of Temnocephala is updated. Comparison between the shape of the cirrus of the temnocephalans associated with trichodactylid crabs is also provided.
