A new species of sucking louse (Phthiraptera: Anoplura: Linognathidae) from Günther's Dikdik (Madoqua guentheri) in Kenya

Linognathus samburi n. sp. is described from adult male and female specimens collected from a juvenile female Gunther's dikdik (Madoqua guentheri) live-trapped near Olturot Village, Samburu district (Rift Valley Province) in northern Kenya. The new species is distinguished from other species of Linognathus including Linognathus geigyi and Linognathus damarensis, both of which parasitize Kirk's dikdik (Madoqua kirkii). A dichotomous key to the species of Linognathus that are known to parasitize dikdiks is included.
