TL;DR: The rate of sequence change in the 16S-23S rDNA of the psyllid P endosymbiont was considerably higher than that of other bacteria, including other fast-evolving insect endosYmbionts.

TL;DR: A revised classification for the world jumping plant-lice (Hemiptera: Psylloidea) is presented comprising all published family and genus-group names and forty two new species combinations are proposed resulting from new genus- group synonymies and a replacement name.

TL;DR: The use of the term host-plant is suggested to be restricted to plants on which a psyllid species completes its immature to adult life cycle, and the terms overwintering or shelter plant, food plant, and casual plant are suggested.

TL;DR: The gall-forming psylloid fauna associated with the temperate Neotropical plant genus Schinus is revised, and keys are provided for adults, larvae and galls, and cladistic analyses suggest that the Schinus inhabiting calophyids form two monophyletic groups.

TL;DR: It is shown that contrary to general belief, developed and heavily-studied parts of the world are important reservoirs of unknown species, and the importance of developing a system that better supports and guides this formidable workforce as they seek to overcome the Taxonomic Impediment and speed up the process of describing the planetary biodiversity before it is too late.
