Coccidella Hambleton, 1946, Biol. Soc. Wash. Proc. 59 : 177. 



type-species: Morrisonella poensis Hambleton, 1946, by substitution of 

 Coccidella for Morrisonella Hambleton. 



The describer proposed this new name for Morrisonella Hambleton, 1946, pre- 

 occupied by Morrisonella Bartsch, 1943, in the Mollusca. Ferris, 1953a: 426. 

 considered Coccidella a synonym of Rhizoecus Kiinckel d'Herculais. 



Coccidohystrix Lindinger, 1943, Ztschr. der Wien, Ent. Gesell. 28 : 

 218. 



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

 nation and monotypy. 



Lindinger, 1943b : 219, proposed this generic name as a substitute for Ecliinococ- 

 cus Balachowsky, 1936c : 157, preoccupied in Vermes. For further discussion of 

 associated complications, see under Centrococcus Borchsenius. 



Coccilacca Amyot, 1847, Soc. Ent. de France Ann. (ser. 2) 5 : 495. 



This is a uninomial designation with no validity as a generic name, although 

 it is listed in Neave, 1939, Xomen. Zool. 1 : 778. We presume that it is intended 

 to stand for Coccus lacca Kerr. 



Coccinella Gmelin, 1766, Onomatologia Hist. Nat. Completa 3 : column 

 22. 



This was used by the author as a pseudogeneric name to designate the cochineal 

 insect. In the same volume it was also used (col. 27) for the genus Coccinella in 

 the Coleoptera. We believe that the coccid usage has no nomenclatorial status. 



Coccionella Gmelin, 1766, Onomatologia Hist. Nat. Completa 3 : col- 

 umn 22 ; Halmemanns, 1793, Apothekerlexikon 1(1): 193. 



Gmelin used this name as a uninomial to designate the cochineal coccid. We 

 believe that this usage does not give the name generic standing in the Coccoidea. 

 Hahnemanns used the name as an apparent generic unit in association with a 

 species Coccionella polonicus [Linnaeus, 1758], writing the name in italics. He 

 also used the name as a uninomial in the same alphabetical sequence to refer to 

 what we presume is the true Mexican cochineal coccid, which he further referred 

 to, in the same sequence, under the name "Coccus Cacti L." which was written in 

 Roman type. Neave, 1939, Nomen. Zool. 1 : 778, noted only the 1860 use of this 

 name by Voet in the Coleoptera. Lindinger, 1954 : 614, who discovered the 1793. 

 apparently binomial, use of this name for a coccid, presented the case for accept- 

 ance. After examining the original Hahnemanns presentation, we reluctantly 

 conclude that it is possible to interpret the latter's treatment (names presented 

 in italics) as a binomial scientific name, even though he presented all otber coccid 

 binomials that were noted in his Lexicon in undifferentiated Roman type -e.g. 

 "Coccus Cacti L." However, we cannot agree with Lindinger's use of the name 

 as a total replacement for Margurodcs Guilding, 1S29, sensus latus. There lias 

 been sufficient work in recent years, notably by Silvestri, 1936-1939a, to demon- 

 strate clearly that Margarodes sensus latus is a complex of morphologically 

 diverse species which can legitimately go into several distinct genera. Therefore 

 Coccionella, if accepted, can replace only Porphyfophora Brandt, 1833.
