Xylotoles costatus Pitt Island Longhorn: a manual with aids to identification
The Pitt Island longhorn, Xylotoles costatus, is a medium sized (17 - 20 mm long) beetle. It is the largest of a number of species of longhorn beetles, (family Cerambycidae) that occur on the Chatham Islands. Beetles of this family can generally be recognised by their elongate shape and long antennae, that are normally at least three quarters of the length of the beetle and sometimes even longer then the beetle.
