Psylla fulguralis Kuwayama, 1908: 177 .

Cacopsylla fulguralis; Park (1996: 271).

Cacopsylla (Hepatopsylla) fulguralis; Kwon & Kwon (2020: 150).

Distribution in Korea. GB, GG, GN, JJ, JN (Park et al 1980 b, as Psylla fulguralis; Lee & Kwon 1981, as P. fulguralis; Kwon 1983, as P. (Hepatopsylla) fulguralis; Anonymous 1994, as P. fulguralis; Kwon et al. 1996c, as P. fulguralis; Kwon & Kwon 2020, as Cacopsylla (Hepatopsylla) fulguralis) (KNA, NAAS, SNU).

Host plant. Elaeagnus glabra Thunb., E. macrophylla Thunb. (Elaeagnaceae) (Kwon 1983).

Comments. Kwon & Kwon (2020) synonymised four Chinese species with C. fulguralis which, however, are morphologically close to the Indian C. quadrimaculata (Mathur, 1975) . We have not examined specimens of the four Chinese species and cannot judge if they are synonymous with C. quadrimaculata . Pending a revision of relevant type material we consider the Chinese taxa as good species: C. cyphospila Li, 2011, stat. rev., C. fluctimaculata Li, 2005, stat. rev., C. gossypinmaculosa Li, 2011, stat. rev., and C. nigrigenimacula Li, 2011, stat. rev. (misspelt as C. nigrigenimaculata). Cacopsylla fulguralis (material examined from France, Germany, Korea and Switzerland; KNA, NAAS, NHMB, SNU) differs from C. quadrimaculata (material examined from Nepal; NHMB) in the larger body size, the longer genal processes, the longer antennae and the longer apical process of the female proctiger. Cacopsylla maculiumbellatae (Li & Yang, 1987) (paratypes examined; MHNG), another close species from China, constitutes a good species. It is slightly larger than C. fulguralis and has shorter genal processes and narrower forewings than C. quadrimaculata .
