An annotated checklist of the Cook Islands psyllids with keys to the species and two new records (Hemiptera, Psylloidea)

Abstract

An annotated checklist of the psyllids of the Cook Islands is presented. The presence of Syntomoza tahuata (Klyver, 1932) and Trioza alifumosa Klyver, 1932 in the archipelago, based on new material collected, is reported for the first time. This is the first record from these islands of the genus Syntomoza and the family Liviidae. An identification key to the psyllid species known from the Cook Islands is provided, and their origin and provenance are discussed in relation to their biogeographic implications.
