Description of Four New Myxosporean Species (Myxozoa: Myxosporea) from Genus Myxobolus, Fish Parasites of Burkina Faso, West Africa

The Myxosporean met in freshwater fishes of Burkina Faso, form all of them some whitish cysts on the fins for Myxobolus labeoi sp. n. and Myxobolus tingrelaensis sp. n. and on the branchial for Myxobolus heterotisi sp. n. and Myxobolus sourouensis sp. n. The spores of M. heterotisi sp. n. are ootid, they measure 2.13A‚±0.46 out of 9.51A‚± 0.45 AŽÂ¼m and have their anterior extremity slightly contracted. Their pyriform polar capsule measure 6.41A‚±0.41 out of 3.53A‚±0.51 AŽÂ¼m. The polar filament is rolled in 10 turns of spires. M. labeoi n. sp. Presents some lengthened spores of 16.43A‚±0.50 out of 10.73A‚±0.52 AŽÂ¼m. The dissymetrical polar capsules measure 8.37A‚±0.56 out of 6.53A‚±0.68 AŽÂ¼m and 1.57A‚±0.17 out of 0.35A‚±0.09 AŽÂ¼m. On M. sourouensis sp. n., the spores measure 11.33A‚±0.33 out of 8.84A‚±0.72 AŽÂ¼m. The polar capsules are ootid measuring 5.77A‚±0.73 out of 2.32A‚±0.46 AŽÂ¼m. M. tingrelaensis sp. n. form some ootid spores of 11.6A‚±0.62 out of 9.37A‚±0.67 AŽÂ¼m. The pyriform polar capsules are 4.80A‚±0.55 out of 2.40A‚±0.38 AŽÂ¼m and have a small inter-capsular appendix.
