Onchocerca dewittei n. sp. est récoltée chez le Sanglier au niveau des métatarses (tendons et conjonctif sous-cutané) ; elle est distincte par la cuticule de la ♀, à côtes rectilignes se chevauchant dans les champs latéraux et la microfilaire relativement épaisse (228-247 µ de long et 6-7 µ de large). Cette Onchocerque de Suidé présente certains caractères primitifs (côtes rectilignes, persistance de dix paires de papilles caudales chez le ♂), mais est dans l’ensemble nettement plus évoluée qu’O. raillieti Bain, Müller et coll., 1976, parasite d’Equidés.
Abstract
Onchocerca dewittei n. sp. was collected from a wild Boar at the metatarse level (tendons and subcutaneous connective tissue) ; it can be differentiated from other species by the female cuticle showing straight ridges which overlap in the lateral fields, and by its relatively thick microfilaria (length 228-247 µ and width 6-7 µ). This suidean Onchocerca displays some primitive characters such as straight ridges and persistency of ten pairs of caudal papillae in the male ; but as a whole this species is undoubtedly more highly evolved than O. raillieti Bain, Muller and coll., 1976, a parasite of Equidae.
