Abstract

Thelohanellus bicornei n. sp. (Myxosporea, Bivalvulida) is described from gill of Labeo coubie (Rüppel, 1832) (Osteichthyen, Cyprinidae) in Burkina Faso, West Africa.

Their posterior end is rounded and their anterior part shows two "horns like" expansions. Spores measured 13,5 ± 0,56 (13-14) μm in length and 8,43 ± 0,49 (8-9) μm in width. Horns length is 1 to 1,5 μm long. Polar capsule is piriform, it's length is 7,24 ± 0,45 μm and the width 3,75 ± 0,32 μm. The polar filament formed 10 turns.
