Key morphological characters of Ixodes nairobiensis female. A Dorsal view (1—scutum rhomboidal, tapering to rounded posterior end, length to width ratio approx. 1.5; 2—lateral carinae straight; 3—cervical grooves shallow but broad). B Dorsal view of basis capituli (1—basis capituli triangular, its anteriolateral edge straight, supported from behind by a caudally tapering dark area of sclerotization; 2—small, rounded, caudally directed cornuae; 3—palps "stalked", approximately four times as long as broad at their maximum width, ratio of length of palpal segment II to III approximately 1.7; white dashed line indicates indistinct separation of segments II-III; 4—hair longest posteriorly on palpal segment II, one short hair on its caudolateral protuberance). C Ventral view of basis and coxae (1—well-developed, tapering and pointed auriculae, directed posterolaterally; 2—palpal segment I with flange-like extension and (3) two hairs; 4—coxa I with caudomedially directed spur, not in line with medial edge of coxa I)
