Drymococcus Borchsenius, 1962, Akad. Nauk SSSK Zool. Inst. 

 Trudy 30: [221]. 



type-species : Drymococcus rhizophilus Borchsenius, 1962, by original desig- 

 nation and monotypy. 



This genus was assigned by its describer to the Planococcini, Pseudococcidae, 

 where it is considered close to Formicococcus Takahashi. 



Dryocecis Amyot, 1847, Soc. Ent. de France Ann. (ser. 2) 5 : 501. 



This is a uninomial designation for a coccid species, Chermes variegata Olivier, 

 which is currently assigned as a synonym of Eermes roooris (Fourcroy). 



Duplachionaspis MacGillivray, 1921, The Coccidae, p. 307. 



type-species: Chionaspis graminis Green, 1896, by original designation. 



MacGillivray included 21 species in this genus. Recent workers have accepted 

 it as a zoologically valid unit. Balachowsky, 1954e: 171, assigned it to his 

 Diaspidina, group II, chionaspiform. 



Duplaspidiotus MacGillivray, 1921, The Coccidae, p. 394. 



type-species : Pseudaonidia clavigera Cockerell, 1901, by orginal designa- 

 tion. 



The author placed this genus close to Pseudaonidia Cockerell. Ferris, 1937c : 

 51, 54, was doubtful of its distinctness, but later, 1938a : SII-252, accepted it as 

 zoologically valid. Balachowsky, 1958b : 256-257, 268-269, accepted it and used 

 it for species included in his study of African diaspidid coccids. 



Duplaspis Goux, 1937, Soc. Ent. de France Bui. 42 : 229. 



type-species : Duplaspis fraxini Goux, 1937, by original designation and 

 monotypy. 



Its describer placed this genus in the Diaspidini. Balachowsky, 1954e: 168, 

 accepted it and placed it in his Diaspidina, group II, chionaspiform. 



Dycryptaspis Cockerell, 1897, in Leonardi, Eiv. di Patol. Veg. (Nov. 

 1896-Feb. 1897) 5 : 375 ; 1897, U.S. Dept. Agr., Div. Ent., Tech. 

 Ser. 6 : 31. 



type-species : Aspidiotus secretus Cockerell, 1896k : 20, by original desig- 

 nation and monotypy. 



Leonardi discussed this name, crediting it to Cockerell and suppressing it as 

 a synonym of his Odonaspis in a short published note in which he remarked 

 on the details of a letter received from Cockerell after the publication of the 

 Leonardi, 1897: 283-286, preliminary note on aspidiotine classification. Cock- 

 erell, in the reference cited, accepted Leonardi's suppression of his name in favor 

 of Odonaspis, although without actual mention of Dycryptaspis. Lindinger, 

 1937: 184, 191 accepted Dycryptaspis Cockerell as valid nomenclatorially and 

 as a replacement for Odonaspis Leonardi which he regarded as preoccupied 

 by Odontaspis Agassiz, 1845. For further discussion on this problem, see 

 Odonaspis Leonardi and Spatheaspis Leonardi. In spite of the emphasis Lin- 

 dinger gave to this name, it does not seem to be included in Neave's Nomenclator 

 Zoologicus.
