AN ANNOTATED LIST OF GENERIC NAMES OF THE COCCOIDEA 65 



Dynaspidiotus Thiem and Gerneck, 1934, Arb. iiber Physiol, u. An- 

 gew.Ent. 1:131,230-231. 



type-species : Aspidiotus britannicus Newstead, 1898, by original designa- 

 tion. 



As a result of the unusual method used by these authors in presenting what 

 seem to be extensive, critical, morphological studies, it is quite difficult to 

 evaluate this genus properly. It was presented first (p. 131) as a subgenus, in 

 the list of species studied. It appears to us to have been presented as both 

 a nomenclatorial and a zoological unit much later in the paper (p. 231) , where it 

 was included in a key to the groups and species of Aspidiotini studied. The 

 manner of presentation at this point ". . . Genus Dynaspidiotus (syn. 

 Aspidiotus s. str.) (Typ: britannicus. Included hederae, abietis)" leaves no al- 

 ternative to the conclusion that it is nomenclatorially a synonym of Aspidiotus 

 Bouche. Acceptance of the existence of a zoologically independent unit, based 

 initially on Aspidiotus britannicus Newstead, appears to date from Ferris, 

 1938a: SII-228, where he credited the genus to Thiem and Gerneck. Subse- 

 quent authors, including Balachowsky and Schmutterer, have followed this 

 pattern, so the genus is now fairly well established in literature. It is our 

 belief that the aspidiotine genera are much in need of critical classificatory 

 studies, and that the zoological status of this unit must be considered as un- 

 settled at present. 



Dysmicoccus Ferris, 1950, Atlas of the Scale Insects of North 

 America (ser. 5) [v. 5] : 22, 53. 



type-species : Dactylopius brevipes Cockerell, 1893, by original designation. 



This genus was separated from Pseudococcus Westwood to care for a group 

 of 13 species, most of which were assigned to Pseudococcus previously. On the 

 basis of present knowledge of the species in this group, the separation can be 

 maintained only on very narrow grounds. 



Echinicerya Morrison, 1930, Biol. Soc. Wash. Proc. 43 : 17. 



type-species : Echinicerya anomala Morrison, 1930, by original designation 

 and monotypy. 



Its describer placed this genus in the Iceryini, Monophlebinae. 



Echinococcus Balachowsky, 1936, Soc. Ent. de France Bui. 41 : 157. 



type-species : Echinococcus echinatus Balachowsky, 1936, by original desig- 

 nation and monotypy. 



This generic name was preoccupied by Echinococcus Rudolphi, 1801, in Vermes. 

 Lindinger, 1943b: 219, recognized this prior usage and proposed the name 

 Coccidohystrix as a replacement. Borchsenius, 1948a : 953 ; 1949 : 307, also noted 

 the preoccupation and suggested the name Centrococcus. See the discussion 

 under Centrococcus.
