| − | These species were previously endiginous to the 'Old World', but have now been spread to a range of habitats worldwide and are important vectors of several infectious agents. They can generally be identified by;
| |
| − | *Inornate scutums
| |
| − | *Short palps
| |
| − | *Eyes present
| |
| − | *Festoons on posterior margin
| |
| − | *Comma shaped spiracles

| − | This is considered the most serious external parasites of Australian cattle, though they also affect cattle accross the southern hemisphere and the southern states of the USA. It is able to complete its life cycle in just 2 months under optimal conditions and lay 2000 - 3000 eggs during this time. It is important in its ability to act as a vector for ''Babesia bigemina'', ''Borrelia theileri'' in South America and in Australia of ''Coxialla burnetti'' and ''Anaplasma marginale''. These organisms can be passed down for up to 5 generations of ticks regardless of the hosts on which they feed as they can be passed transovarially between generations.
