Original Paper


Light microscopic description was presented for a new myxosporean species, Auerbachia bajadi. The parasite was collected from the gallbladder of orangespotted trevally Carangoides bajad (Forsskål, 1775) in Al-Quseir city, Red Sea coast, Egypt. The prevalence was 30/80 (37%) and the infection was reported as an enormous amount of free mature spores floating in the bile. Spores were club-shaped with a broad anterior part and a narrow caudal part. Shell valves were asymmetrical and the larger valve was drawn into a wide caudal projection. The mean spore measurements were 22.7 μm in total length and 9.5 μm in width. Polar capsule was single and elliptical-shaped with five polar filament turns. The polar capsule measured 9.5 μm in length and 4.5 μm in width. The spores were distinctly different from the four recorded species of genus Auerbachia. One of the cited species of this genus was excluded as it was related to genus Coccomyxa than genus Auerbachia. Also, the accurate citation date of this genus was discussed.
