Endangered
Xylotoles costatus
Xylotoles costatus
Xylotoles costatus is a beetle in the family Cerambycidae (order Coleoptera), recorded as Endangered and tied to New Zealand.
Appearance
Both species are coloured black with a green bronze sheen, however it is likely that X. Costatus has more of a bronze sheen than X. Traversii.
Even so, if a longhorn beetle specimen is found in the Chatham Islands that is greater than 16 mm in length it is likely to be X. Costatus.
Range and habitat
This species of longhorn beetle is usually found on the trunks of Coprosma chathamica at night. Xylotoles costatus, the Pitt Island longhorn beetle, is a beetle in the family Cerambycidae. It is endemic to the Chatham Islands.
Once thought to be extinct, it is now known to survive on South East Island/Rangatira. Being therefore an example of a so-called "Lazarus taxon". This species has not been seen at its type locality of Pitt Island since 1907 despite extensive surveys for it since 1990.
