type-species : Coccus hesperidum Linnaeus, 1758, by subsequent designation 

 of Cockerell, 1893g : 49. 



Burmeister was the first to present this name in print, crediting it to Illiger, but 

 nothing has been found in literature to justify acceptance of Illiger as author. 

 No definite type designation was made but detailed descriptions were given for 

 five species of which L. hesperidum (Coccus hesperidum Linnaeus) stood first. 

 A final paragraph listed five other species "which must belong in this genus," 

 among them Coccus tiliae Linnaeus and Coccus coryli Linnaeus. Westwood, 

 1840:118, listed "Lecanium 111. (L. hesperidum Linn., Burm . . .)" which has 

 been accepted by some as a type designation. However, the first definite type 

 designation was made by Cockerell, 1893g : 49, when, discussing the Signoret 1873 

 division of the genus Lecanium into six groups of genera, he stated : "First Series. 

 Consists of flat and often viviparous species of which L. hesperidum L. may be 

 taken as type." In the same article he proposed Eulecanium as a subgeneric 

 name "taking L. tiliae as the type," for the third series, "hemispherical species 

 with skin more or less tessellated, living on trees and shrubs in North America 

 and Europe." This described the zoological unit that has appeared in literature 

 over the years under the name of Lecanium.
