AN ANNOTATED LIST OF GENERIC NAMES OF THE COCCOIDEA 105 



Cockerell, 1901c : 91, and 1902k : 453, reported that Lecanium Burmeister, 1835, 

 with the same type-species as Calymnatus Costa, 1828, must be abandoned in 

 favor of the prior genus. Fernald, 1903b : 167, accepting CockerelTs conclusion, 

 placed Lecanium and the Costa genera Calymmata and Calypticus as synonyms 

 of Coccus Linnaeus with type-species hesperidum Linnaeus. Green, 1904d:248 

 and 1922 : 461, recognized the suppression of Lecanium in favor of Coccus, but 

 continued to use the name Lecanium for this zoological unit that "has never been 

 known under any other generic name." Sanders, 1909 : 430, autocratically set 

 persicae (Fabricius) as type-species of Lecanium, because "all the species Bur- 

 meister really placed under this genus have been removed to other genera except 

 persicae'' and "it is impossible to eliminate Lecanium from our Coccid nomencla- 

 ture." There is no rule that will permit this action. Steinweden, 1929 : 225, 

 accepted this genus as Lecanium Illiger with type-species "Coccus tiliae Linnaeus 

 or Coccus coryli Linnaeus" but the facts detailed above show no justification for 

 such a presentation. Sulc. 1908 : 36, recognized Eulecanium Cockerell as a genus 

 that included most Palearctic species (not in hot houses) of the genus Lecanium 

 (sensu Signoret) and proposed the removal of certain of the species having salient 

 differential characters to three new genera. In his 1923 paper, Sulc used the 

 name Lecanium, demoting to subgenera the four previously recognized genera — 

 Eulecanium Cockerell, Palaeolecanium Sulc, Parthenolecanium Sulc, and Sphaero- 

 lecanium Sulc. Kawecki, 1958, followed this Sulc usage. Borchsenius, 1957 : 384, 

 423, acceded to the suppression of Lecanium, and accepted the three Sulc sub- 

 genera and Eulecanium Cockerell as valid genera. See Eulecanium for further 

 details. 



Lecanochiton Maskell, 1882, Xew Zeal. Inst. Trans, and Proc. (1881) 

 14:222. 



type-species : Lecanochiton metrosideri Maskell, 1882, by monotypy. 



Morrison and Morrison, 1922: 69-75, redescribed this coccine genus and its 

 type-species, but were unable to offer suggestions as to its relationships. 



Lecanodiaspis Targioni-Tozzetti, 1869, Soc. Ent. Ital. Bui. 1: 261. 



ttpe-spectes : Lecanodiaspis sardoa Targioni-Tozzetti, 1869, by monotypy. 



Signoret, 1870: 285, used this spelling, agreeing with the Targioni original 

 presentation, in his index and in his detailed treatment of the genus and its 

 single associated species. The spelling Lecaniodiaspis, which appeared on page 

 272 of Signoret's work, we believe to be a lapsus and, although it has been in 

 general use in literature for many years, should give way to Lecanodiaspis 

 Targioni-Tozzetti, 1869. Borchsenius, 1959a : 840, erected a new family, the 

 "Lecaniodiaspididae," to include this genus and several others previously placed 

 in the Asterolecaniidae. 



Lecanopsis Targioni-Tozzetti, 1868, (separate) Soc. Ital. di Sci. Nat, 

 Atti 11: 36; 1869, 11: 729. 



type-species : Lecanopsis rhyzophila Targioni-Tozzetti, 1868, by monotypy. 



Targioni, 1867 : 23, first mentioned this lecanine hypogeous genus as Rhizobium, 

 referring to it a "large species found near the roots of an Asperula." This name, 

 emended to Rhyzooium, appeared in his catalog, 1868: 36, as a synonym of 

 "Lecanopsis nob., gen. nov." with species "rhyzophila nob., n. sp." Signoret, 

 1874 : 93, published the first formal characterization of the genus as quoted notes
