AN ANNOTATED LIST OF GENERIC NAMES OF THE COCCOIDEA 69 



Eriococcus Targioni-Tozzetti, 1868, (separate) Soc. Ital. di Sci. Nat. 

 Atti 11: 33; 1869, 11: 726. 



type-species: Coccus ouxi Fonscolombe, 1834, by subsequent restriction of 

 Signoret, 1872 : 429. 



This is another early coccid genus with a tangled history. It was first pro- 

 posed by Targioni-Tozzetti in 1868 : 33, as "Gen. 9. Eriococcus nob." with five in- 

 cluded species, all previously described in Coccus Linnaeus, but no type was 

 selected or indicated. Signoret, 1870: 283, removed one of the five included 

 species to a new genus of his own and in the process remarked that he was reserv- 

 ing Eriococcus "for C. festucae Fonsc." We do not regard this as type-species 

 fixation in the face of the requirements of Article 67(b) of the Code. A little 

 later, Signoret, 1872 : 422, 429, concluded that "Coccus ouxi Fonscolombe is a true 

 Coccite and for it we will retain the name of Eriococcus Targioni." This we 

 accept as adequate type-species designation. Lindinger, 1933a: 77, discussed 

 the status of Eriococcus at some length and pointed out, correctly we believe, 

 that Fernald, 1903b: 70, should have designated Coccus ouxi Fonscolombe as 

 type-species of Eriococcus, rather than Coccus crispus Fonscolombe. Rather 

 than accept this, however, Lindinger applied his own personal standard of 

 selecting the first species included in any multispecific genus as its type-species. 

 This approach led him to designate Coccus festucae Fonscolombe as the type- 

 species of Eriococcus, resulting in a very different zoological concept for the 

 genus, and in his substitution of the name Nidularia Targioni-Tozzetti for the 

 zoological concept of genus Eriococcus, as most coccid workers have accepted it. 



Borchsenius, 1948: 501, reviewed this action by Lindinger and rejected the 

 latter's type-species selection of Coccus festucae for Eriococcus. Borchsenius 

 credited the genus to Signoret rather than to Targioni-Tozzetti on the ground 

 that the latter's presentation was a nomen nudum. On this we disagree, be- 

 lieving that the Targioni-Tozzetti presentation constituted establishment through 

 indication in accordance with the requirements of Article 16(a) (v) of the Code. 

 As generally accepted zoologically, Eriococcus is a large genus containing 

 numerous species described from many places in the world. Borchsenius, how- 

 ever, restricted the genus zoologically to the single type-species ouxi on the 

 ground that it alone possessed a certain specialized type of tubular duct, and 

 transferred the majority of other described Eriococcus species to the genus 

 Acanthococcus Signoret, 1875, which has long been regarded as a synonym of 

 Eriococcus. We have examined specimens of ouxi and have studied the spe- 

 cialized ducts on which his action is based. Our present view is that a critical 

 morphological study of the whole eriococcine fauna of the world should be un- 

 dertaken before wholesale transfer is accepted completely. Hoy, 1962: 29-30, 

 and 1963, New Zeal. Dept. Sci. and Indus. Res. Bui. 150 : 8, reviewed the situa- 

 tion and rejected the Borchsenius actions, regarding both Acanthococcus Signoret 

 and Rhizococcus Signoret as synonyms of Eriococcus Targioni-Tozzetti. 



Eriodes Betrem, 1937, Arch. v. Koffiecult. Nederland Indie 11 : 24, 99. 



A lapsus for Erioides Green. This name, as spelled by Betrem, is preoccupied 

 by Eriodes Geoff roy, 1829, in Mammalia. 



Erioides Green, 1922, The Coccidae of Ceylon. Part V, p. 365. 



type-species : Erioides cuneiformis Green, 1922, by original designation. 



This is a pseudoeoccid genus that has not been placed more precisely within that 

 family. Lindinger, 1943b : 219, reviewed the nomenclatorial status of the name
