Cacopsylla evodiae (Miyatake) Inoue, 2010

Inoue, Hiromitsu, 2010, The generic affiliation of Japanese species of the subfamily Psyllinae (Hemiptera: Psyllidae) with a revised checklist, Journal of Natural History 44 (5 - 6), pp. 333-360 : 344-345

Cacopsylla evodiae (Miyatake) comb. nov.

Psylla evodiae Miyatake 1965a, p 176 ; Hodkinson 1983, p 358; Yang 1984, p 108; Hodkinson 1986, p 326; Inoue et al. 2006, p 66. Type locality: Japan (Ryukyus).

Cacopsylla evodiae is probably most closely related to an Indian species Psylla murrayi Mathur, 1975 , which feeds on Murraya koenigii (L.) Spreng. ( Rutaceae ) ( Mathur 1975) and should be transferred to the genus Cacopsylla in the future. In addition, Cacopsylla evodiae is similar to two Taiwanese Rutaceae-feeding species, Cacopsylla toddaliae ( Yang, 1984) , which feeds on Toddalia asiatica (L.) Lam. and is newly recorded from Japan in the present study, and also to Psylla fagarae Fang and Yang, 1986 , which feeds on Fagara cuspidata (Champ.) Engl. ( Fang and Yang 1986) and should be transferred to the genus Cacopsylla in the future, particularly in the nymphal morphological features.
