Two populations of Paracichlidotherus (Ciliophora. Nyctotheridae) were collected from the intestines of the Surgeon‐fishes, Zebrasoma flavescens. and Acanthurus nigricans , from waters around the island of Guam. They were examined after Protargol staining and compared with the type population for 14 morphological characters. Right and left posterior short kinetal rows of very close kinetosomes and apparently fused cilia are described based on light microscopy and scanning electron microscopy. They often appear to be part of a second posterior suture system on each side. From transmission electron microscopic studies, kinetid structures of somatic dikinetids are described and compared for normal and fused cilia. They are similar, but in the latter, a fibril connects adjacent dikinetids. The buccal overture is V shaped at its posterior aspect. The genus is described more fully based on these characteristics.
