Dermacentor tick comparisons

Researchers have split the medically important American dog tick into two species: the existing Dermacentor variabilis in eastern states and the newly described Dermacentor similis west of the Rocky Mountains. Shown here: D. variabilis male, dorsal view (top left) and ventral view (top middle); D. similis male, dorsal view (bottom left) and ventral view (bottom middle); and views of spiracular plates of males (A-D, D. variabilis, and E-H, D. similis).
