Myxidium elmatboulii n. sp. and Ceratomyxa ghaffari n. sp. (Myxozoa: Myxosporea) parasitic in the gallbladder of the Red Sea houndfish Tylosurus choram (Rüppell, 1837) (Teleostei: Belonidae) from the Red Sea, Egypt

Abstract

Two new myxosporean species, Myxidium elmatboulii n. sp. and Ceratomyxa ghaffari n. sp., are described from the gallbladder of the Red Sea houndfish Tylosurus choram (Ruppell, 1837) from the Gulf of Suez, Red Sea, Egypt. Diagnostic features of Myxidium elmatboulii n. sp.: plasmodia disporous, spherical in shape. Spores s-shaped with smooth surface and measures 20.7 (19.0-23.0) × 10.6 (9.0-12.0) × 10.4 (8.5-12.0) μm. Polar capsules pyriform with 9-10 polar filaments, measuring 9.10 (8.0-10.0) × 3.8 (3.5-4.0) μm. Spores of Ceratomyxa ghaffari n. sp. slightly crescent-shaped, measuring 7.6 (6.0-9.0) × 29.9 (25.0-33.0) μm. Polar capsules typically rounded, 3.3 (3.0-4.0) μm in diameter with 5 filament turns.
