SYSTEMATICS

Subfamily: Eulecaniinae. Tribe: Eulecaniini. The status of the genus Lecanium Burmeister has been discussed at great length by various authors, but was finally clarified when Lecanium Burmeister, Type species Coccus hesperidum Linnaeus, was placed on the Official Index of Rejected and Invalid Generic Names in Zoology with the name number 2155 under the plenary powers of the International Commission on Zoological Nomenclature, Opinion 1303. The genus Sphaerolecanium Leonardi, 1908a, was erected in July, 1908 with Chermes emerici Planchon as the Type species. Leonardi's generic name was preoccupied by Sphaerolecanium Śulc (described in February, 1908, with Type species Coccus prunastri Fonscolombe) (see Hodgson, C.J. 1994. The scale insect family Coccidae: an identification manual to genera. Wallingford, Oxon, UK : CAB International Institute of Entomology 639 pp.). Silvestri (in Leonardi, G. 1920. Monografia delle cocciniglie Italiane. Portici : Della Torre 555 pp. [312]) suggested that Sphaerolecanium Leonardi must be considered a synonym of Eulecanium and that Chermes emerici was a synonym of E. coryli now E. tiliae. Hodgson (1994a: 546) studied four slides labelled Chermes emerici, which were considered "probably Leonardi's original specimens", but could not confirm their synonymy with E. tiliae. Until the exact status of L. emerici will be established, Sphaerolecanium Leonardi is considered a synonym of Eulecanium.
