Psyllinae Latreille, 1807

Cho, Geonho, Burckhardt, Daniel & Lee, Seunghwan, 2022, Check list of jumping plant-lice (Hemiptera: Psylloidea) of the Korean Peninsula, Zootaxa 5177 (1), pp. 1-91 : 35

Psyllinae Latreille, 1807

Comments. Kwon & Kwon (2020) referred Anomoneura Schwarz to the subfamily Anomoneurinae . Immatures of Anomoneura resemble morphologically those of Psylla and Spanioneura ( Ossiannilsson 1992; Liao & Yang 2018) suggesting a close phylogenetic relationship of the three genera. We, therefore, follow Burckhardt et al. (2021) and treat Anomoneura as a member of the Psyllinae .

Kwon & Kwon (2020) subdivided the genus Psylla Geoffroy, 1762 into the subgenera Koreopsylla Kwon & Kwon, 2020 and Psylla s. str. as well as the genus Cacopsylla Ossiannilsson, 1970 into the subgenera Cacopsylla s. str., Edentatipsylla Li, 2005 (misspelt as Edentipsylla), Hepatopsylla Ossiannilsson, 1970 , Megapteripsylla Kwon & Kwon, 2020 and Thamnopsylla Loginova, 1978.

Cacopsylla visci ( Curtis, 1835) , the type species of the monotypic subgenus Koreopsylla , does not match the diagnosis and circumscription of Psylla provided by Cho et al. (2019b) and Burckhardt et al. (2021), respectively. Rather,the species agrees with the concept of Cacopsylla by Burckhardt et al.(2021).For this reason, Koreopsylla , syn. nov., is synonymised with Cacopsylla and C. visci is referred to Cacopsylla rather than to Psylla (Koreopsylla) .

The splitting of Cacopsylla into subgenera by Kwon & Kwon (2020) is problematic as these subdivisions are, at least in part, artificial. In the «best ML tree» of Percy et al. (2018: Figure S1 ) species previously referred to the subgenera Cacopsylla s. str. (represented by 2 species) and Thamnopsylla (2 spp.) constitute each a monophyletic clade but not those to Hepatopsylla (15 spp.). Kwon & Kwon (2020) treated Cacopsylla tobirae (Miyatake, 1964) in the subgenus Edentatipsylla (misspelt as Edentipsylla) and Cacopsylla bibari ( Kwon, 1983) in the subgenus Hepatopsylla . Both species are associated with Pittosporum tobira (Pittosporaceae) and are probably closely related, i.e. congeneric, though differing in the absence/presence of a genual spine. Similarly, Cacopsylla japonica ( Kuwayama, 1955) is closely related to C. albopontis ( Kuwayama, 1908) , C. lineaticeps ( Kwon, 1983) and C. pseudosieboldiani ( Konovalova & Loginova, 1985) and shares the host association with Acer (Sapindaceae) . Kwon & Kwon (2020) refer C. japonica to the monotypic subgenus Megapteripsylla , based on the broad forewing, but treat the other three species in the subgenus Hepatopsylla . For this reason we follow Burckhardt et al. (2021) in not recognising subgenera within Cacopsylla , and synonymise Megapteripsylla , syn. nov. with Cacopsylla .
