Pseudohaliotrema paralonchuri sp. n. (Monogenoidea: Dactylogyridae), parasitic on Paralonchurus peruanus (Steindachner) (Teleostei: Sciaenidae) from the Peruvian coast.

Abstract

Pseudohaliotrema paralonchuri sp. n., parasitic on the sciaenid fish Paralonchurus peruanus (Steindachner) from the Peruvian central coast, is described, illustrated and compared with related species of the genus. P. paralonchuri differs from other Pseudohaliotrema by the characteristics of the cirrus, accessory piece, anchors and bars. This is the first record of Pseudohaliotrema from the South American Pacific Ocean.
