Key morphological characters of Ixodes cf. daveyi female. A Morphology of scutum (1—posterolateral edge of scutum with concavity behind maximum breadth; 2—posterior scutal margin rounded; 3—cervical grooves deep, convergent in front, divergent posteriorly; 4—surface of scutum finely punctate, with rugose lateral fields). B Dorsal view of basis capituli and palp (1—cornuae rounded, backwardly projecting protuberances; 2—porose areas very large, subtriangular; 3—basal medial edge of palpal segment II with three long bristles; 4—palpal segment I with ventral protrusion; 5—anteriolateral margin of basis capituli forms a ridge behind palpal basis; 6—auriculae angular, trenchant). C Ventral view (arrow marks horseshoe-shaped anal groove). D Ventral view of basis (1—basis strongly constricted behind auriculae, posterior width similar to that of auriculae; 2—transverse groove behind auriculae, at the level of "waist"; 3—hypostome with fine denticles and broad median unarmed surface). Note that the palp on the right is broken at the base of segment II. E Lateral view of coxae, trochanters (1—coxa I with sharply pointed internal and broad, tapered external spur; 2—coxae II-IV with external spurs, sharp when viewed laterally (decreasing in this order); 3—trochanters with distal spurs as sharp protrusions)
