(Ph.) hexagonus and a simple pictorial key for the identification of their femalesKey features of Ixodes kaiseri females. a Basis capituli, dorsal surface with rounded porose areas. b Basis capituli of another morphotype, with triangular porose areas. c Scutum and basis capituli. d Basis capituli, ventral aspect with coxae I. Numbered arrows indicate (in the order of presentation in the key): (1) cone-like shape of the anterior surface of basis capituli; (2) ridge-like margin of porose area; (3) longitudinal line (starting medially to the basis of external spur), which divides the surface of coxa I; (4) external spur on coxa IBack to article page
