Ortholinea basma n. sp. (Myxozoa: Myxosporea) from Agile klipfish Clinus agilis (Teleostei: Clinidae), light and scanning electron microscopy

Abstract

A new myxosporean parasite, Ortholinea basma n. sp. is described by light and scanning electron microscopy (SEM) from the urinary bladder of Agile klipfish Clinus agilis collected from the tidal pools at Port Nolloth, west coast, South Africa. Pseudoplasmodia are mono- to polysporic appearing as refractile foamy flat mat. Pansporoblasts are mono- and disporic. Spores are characterized by a relatively large size (13.5 X12.3) and special pattern of valvar ridges. SEM revealed that the valvar ridges are wounded concentrically parallel to the main sutural ridge and end up with a circular or oblong central field. Valvar ridges are consistent, regularly spaced, rarely branched and counted 12-13. The employment of SEM in well description and taxonomy of Ortholinea species proved to be essential to reveal the exact pattern of valvar ridges.
