AN ANNOTATED LIST OF GENERIC NAMES OF THE COCCOIDEA 117 



Matsucoccus Cockerell, 1909, Canad. Ent. 41 : 56. 



type-species Xylococcus matsumurae Kuwana, 1905, by original designation 

 and monotypy. 



The author erected this genus for a single Japanese species found on pine, 

 noting that it was related to Callipappus Guerin-Meneville. Herbert, 1921, 

 treated the genus in detail and suggested that it was most closely related to 

 Kuwania Cockerell, Steingelia Nassanov, and Stomococcus Ferris. Morrison, 

 1928 : 48, discussed its relationships and placed it in the Matsucoocini, Xylococci- 

 nae, Margarodidae. Ferris, 1941: 7-8, noted that specimens found in Baltic 

 amber belong to a genus closely related to Matsucoccus.

type-species : Mauritiaspis malloti Mamet, 1939, by original designation.

 MacGillivray. Balachowsky, 1954e : 172, accepted it as valid and assigned it to 

 the Diaspidina, group II, chionaspif orm.

 352, 375. 



type-species : Megalecanium testudinis Hempel, 1920, by original designation 

 and monotypy.

 Cockerell, but larger.
