Abstract The first records of Sitona
discoideus and Trifolium
repens on Norfolk Island are reported. The identities of both
species were confirmed using morphological criteria and nucleotide
sequences. Sequence data from the mitochondrial gene cytochrome oxidase
subunit 1 of the Norfolk Island S. discoideus specimens were
compared with 33 specimens from Australia, New Zealand and France.
These data represent the first published sequences for S. discoideus,
and suggest that Australia or New Zealand was the source of Norfolk
Island’s population. The implications of the introduction of S.
discoideus to Norfolk Island are discussed.
