Tsurushiaspis Balachowsky, 1930, Soc. Ent. de France Bui. (1930) 

 (No. 10): 179. 



A lapsus for Tsukushiaspis Kuwana. 



Tulefiorinia Mamet, 1959, Inst. Sci. de Madagascar, Mem. (1959) 

 (Ser.E.Ent.) 11:461-462. 



type-species : Tulefiorinia simplex Mamet, 1959, by original designation and 

 monotypy. 



The author placed this genua in the Diaspidini, closely related to Thysano- 

 fiorinia Balachowsky. 



Tychea Koch, 1857, Die Pflazenlause Aphiden v. 1 : 296. 



Aphidologists have accepted Tychea Koch as an aphid genus with Tychea 

 graminis Koch as the type-species. Lindinger, 1943b : 265, 1943c : 350, considered 

 it a coccid genus and announced its precedence over Ripersia Signoret, which 

 he placed as a synonym. He placed Tychea graminis Koch as a synonym of 

 Coccus phalaridis Linnaeus, 1758. Lepesme, 1947: 262, presented this concept of 

 Tychea as a valid genus with Ripersia placed in synonymy. Other coccidologists 

 have not accepted it. 



From an examination of the Koch illustrations and descriptions, it is clear 

 that Koch mixed a mealybug and an aphid in his generic characterization and 

 in his illustrations and description of Tychea graminis Koch. T. amycli seems 

 to be an aphid, without question. While the beak, the first item mentioned in 

 the generic description, is that of an aphid, the remaining characteristics cov- 

 ered are coccid, as is the insect chiefly involved in the habitus discussion. As 

 to the figures, that (365) of the fully-developed "stem mother' is a mealybug, 

 and the figure (366a) of the larva seems to be also; the figure (366b) of the 

 "perfect daughter" is that of an aphid. 



Tylococcus Newstead, 1897, Ent. Monthly Mag. 33 : 165. 



type-species : Tylococcus madagascariensis Newstead, 1897, by monotypy. 



A large number of species have been referred to this ant-associated pseudococ- 

 cine genus. Of these, Mamet, 1953: 250, reported that only the four species 

 described from Madagascar and one from the African Gold Coast were probably 

 congeneric. 



Udinia De Lotto, 1963, Roy. Ent. Soc, London, Proc. Ser. B : Tax- 

 onomy 32 : 195. 

 type-species : Udinia scitula De Lotto, 1963, by original designation. 



The author established this genus in the Coccidae (str.) and noted its close 

 resemblance to Saissetia Deplanche. 



Uhleria Cooke, 1881, Treatise on the Insects Injuries to Fruit and 

 Fruit Trees of the State of California, p. 41. 

 type-species : Eriococcus araucariae [Maskell, 1878], by monotypy. 



The author presented "Uhleria araucariae, Comstock" as the name of a coccid 

 found on Norfolk Island Pine at Santa Barbara, with no actual generic descrip- 

 tion or type designation. The sparse descriptive notes were inadequate, but if
