Abstract

Gunung Kinabalu is famous for its exceptionally diverse fauna and flora, rich in endemism. An example is the psyllid genus Ctenarytaina that is represented by four, apparently endemic species. Here two new Ctenarytaina species, C. lienhardi sp. nov. and C. smetanai sp. nov., are described from Gunung Kinabalu. The new taxa are diagnosed, illustrated and their relationships to other species in the genus are discussed. Ctenarytaina daleae Burckhardt is redescribed. The species develops on Leptospermum species (Myrtaceae) and not Syzygium as previously suggested.

An updated classification of the jumping plant-lice (Hemiptera: Psylloidea) integrating molecular and morphological evidence

Daniel Burckhardt, David Ouvrard, Diana Percy (2021)

The classification of the superfamily Psylloidea is revised to incorporate findings from recent molecular studies, and to integrate a reassessment of monophyla primarily based on molecular data with morphological evidence and previous classifications. We incorporate a reinterpretation of relevant morphology in the light of the molecular findings and discuss conflicts with respect to different data sources and sampling strategies. Seven families are recognised of which four (Calophyidae, Carsidaridae, Mastigimatidae and Triozidae) are strongly supported, and three (Aphalaridae, Liviidae and Psyllidae) weakly or moderately supported. Although the revised classification is mostly similar to those recognised by recent authors, there are some notable differences, such as Diaphorina and Katacephala which are transferred from Liviidae to Psyllidae. Five new subfamilies and one new genus are described, and one secondary homonym is replaced by a new species name. A new or revised status is proposed for one family, four subfamilies, four tribes, seven subtribes and five genera. One tribe and eight genera / subgenera are synonymised, and 32 new and six revised species combinations are proposed. All recognised genera of Psylloidea (extant and fossil) are assigned to family level taxa, except for one which is considered a nomen dubium.
