Diplotriaena darnaudii sp. n. (Nematoda: Diplotriaenidae) from D'Arnaud's barbet, Trachyphonus darnaudii

Diplotriaena darnaudii sp. n. is described from 13 specimens collected from the thoracic air sacs of a D'Arnaud's barbet (Trachyphonus darnaudii) originating in the Lake Baringo area of Kenya and which died in captivity in Canada. In morphology it is similar to D. bargusinica Skrjabin 1917, D. campanae Anderson 1959, D. dollfusi Anderson 1959, and D. epsilon Johnston and Mawson 1940, but can be separated from these species by combinations of trident size and spicule size and morphology.
