Comments, identifying features and similar species

Ixodes kerguelenensis is a three host tick that is associated with seabirds and is nitidulous (the off host period is spent in the hosts burrow).  It is thought that male I. kerguelenensis are restricted to the host habitat while the females, nymphs and larvae are all found on the same hosts.

Ixodes kerguelenensis can be distinguished from other Ixodes species that occur in New Zealand by the following features;

The female and nymph of I. kerguelenensis can potentially be confused with that of I. autritulus.  However, I. kerguelenensis is readily identified by the presence of both an internal forwardly directed spur and a mesodorsal spur on palpal article 1.
