Ixodes jacksoni

Host (s) Seabird: Stictocarbo punctatus punctatus.

Note: Information for this species has not yet been entered into the Cane (2011) website. The type material for this species cannot be found, but careful examination of ticks found recently and exclusively on Stictocarbo punctatus punctatus, has shown that, on current evidence I. jacksoni appears to occur only on that host. Because experience is needed to distinguish I. jacksoni from I. uriae, and because the only record of I. uriae from S. p. punctatus (Dumbleton 1961) was from the Banks Peninsula area, we are of the opinion that some, if not all, records of I. uriae from S. p. punctatus (but not other cormorants) may actually refer to I. jacksoni. Preliminary analysis of a partial sequence of the mitochondrial CO 1 gene appears to support this observation (Hardwick & Richards unpublished data). The record in Dumbleton (1961; not Dumbleton 1953 as given by Bishop & Heath 1998) for putative I. uriae collected in 1957 from the same locality and by the same collector (although at a different date) as the I. jacksoni material supplied to Hoogstraal (1967) reinforces our view.
