The Biodiversity Heritage Library works collaboratively to make biodiversity literature openly available to the world as part of a global biodiversity community.

Using molecular (COI, Cytb, H3, wg, 12S, 16S, and 28S) and morphological data (61 characters of adults and immatures), the phylogenetic relationships of the 20 nominal genera of Liviinae were analysed, and the monophyly of the subfamily was tested relative to the other two subfamilies of Liviidae. The analyses of the molecular, morphological, and combined datasets provided similar results with a strong or moderate support in the molecular and combined analyses for the subfamilies of Liviidae and two clades in Liviinae given tribal rank (Liviini and Paurocephalini stat. rev.). Three of the six previously recognized genera were confirmed as monophyletic (Aphorma, Camarotoscena, and Livia) and three were shown to be polyphyletic: Diclidophlebia s.l. (Diclidophlebia s.s., Haplaphalara stat. rev., Klyveria Burckhardt, Serbina and Malenovský, gen. nov., Melanastera Serbina, Malenovský, Queiroz and Burckhardt, gen. nov. and Woldaia stat. rev.), Paurocephala s.l. (Liella Burckhardt, Serbina and Malenovský, gen. nov. and Paurocephala s.s.), and Syntomoza s.l. (Anomoterga stat. rev. and Syntomoza s.s.). The new generic definitions require 38 new and eight revived combinations, including the transfer of two species to other families. All genera of Liviinae are diagnosed and keys are provided for their identification. A checklist of world Liviinae is supplemented.

A checklist comprising information on taxonomy, distribution and host plants is provided for 161 species of jumping plant-lice from the Indian subcontinent (Bangladesh, Bhutan, India, Pakistan, Sri Lanka) based on published records and museum material. In addition there are 15 species recorded in the literature which are identified to genus only. Museum material provides eight new country and two new state (within India) records. The taxonomy is updated and following nomenclatorial acts are proposed: new genus (1), new generic synonymies (2), designation of type species (1), new species synonymies (5), replacement names for primary homonyms at species level (3), new status of subspecies (3), new combinations (23). Toonapsylla Burckhardt, gen. nov. is described for Psylla cedrelae (Kieffer, 1905). The new genus belongs to Mastigimatinae (Calophyidae) and is probably closest related to Bharatiana and Mastigimas, both associated with Cedrela and Toona (Meliaceae). The new genus is diagnosed and a key is provided for the world genera of Mastigimatinae. The Neoptropical genus Allophorina Hodkinson is transferred here from Mastigimatinae (Calophyidae) to Psyllinae (Psyllidae).
