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 Syntomozatahuata (Klyver, 1932) and Triozaalifumosa 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.

Illuminating Insights into the Biodiversity of the Australian Psyllids (Hemiptera: Psylloidea) Collected Using Light Trapping

“…It also includes species of conservation significance, such as those co-threatened on threatened host plants, such as Acizzia hughesae Taylor and Moir, A. mccarthyi Taylor and Moir and Trioza barrettae Taylor and Moir [9,10]. For these reasons, only in the last decade have psyllid studies spanned from biodiversity assessments and regional checklists [11][12][13], to phylogenetic studies [14,15], to new taxonomic species descriptions [16][17][18][19][20], research on insect host-plant interactions [21] and to molecular and genomic analyses focusing on psyllids-bacteria interactions [22,23].…”

Resolving an 87-year-old taxonomical curiosity with the description of Psylla frodobagginsi sp. nov. (Hemiptera: Sternorrhyncha: Psyllidae), a second distinct Psylla species on the New Zealand endemic plant kōwhai

“…This can be facilitated by the continuous updating of psyllid taxonomic diversity and distribution. Good examples tackling Australasia and the Pacific, as a hot spot for biodiversity of the Psylloidea [1, 2], include the most recent works focusing on Australia [6, 7], New Zealand [3, 8, 9], Cook Islands [10] and Hawaii [11, 12]. Expediting this appraisal has been inclusion of molecular phylogenetic studies to enable a better understanding of this superfamily’s evolutionary history (e.g.…”
