Key features of Ixodes canisuga females. a Basis capituli, dorsal surface. b Basis capituli of another morphotype, with considerably smaller porose areas. c Basis capituli, ventral aspect. d Coxa I (short, blunt internal spur viewed from a proper angle). Numbered arrows indicate (in the order of presentation in the key): (1) flat “plateau-like” anterior surface of basis capituli around the hypostome basis; (2) inconspicuous, rounded bump, i.e. slightly forward projecting ridge of “plateau”; (3) relatively straight lateral edge of palp; (4) narrow space between porose areas (i.e. less than their diameter)
