Bulletin of Zoological Nomenclature 1 57 OPINION 1008 SIPHONA MEIGEN, 1803 AND HAEMATOBIA LEPELETIER AND SERVILLE, 1828 (INSECTA: DIPTERA): DESIGNATIONS OF TYPE-SPECIES UNDER THE PLENARY POWERS RULING. — (I) Under the plenary powers all designations of type-species for the nominal genus Siphona Meigen, 1803, made prior to this present Ruling are hereby set aside, and the nominal species Musca geniculata De Geer, 1776, is hereby designated to be the type-species of that genus. (2) The designation by Westwood (1840) of Conops irritans Linnaeus as type-species of Haematobia Lepeletier and Serville, 1828 is hereby confirmed. (3) The following generic names are hereby placed on the Official List of Generic Names in Zoology with the Name Numbers specified: (a) Siphona Meigen, 1803 : 281 (gender: feminine) (type-species by desig-nation under the plenary powers in (1) above Musca geniculata De Geer, 1776) (Name No. 1989); (b) Haematobia Lepeletier and Serville, 1828 : 499 (gender: feminine) (type-species Conops irritans Linnaeus, 1 758 by designation of West-wood, 1840) (Name No. 1990); (4) The following specific names are hereby placed on the Official List of Specific Names in Zoology with the Name Numbers specified: (a) geniculata De Geer, 1 776 : 38 as published in the binomen Musca geniculata De Geer (type-species of Siphona Meigen, 1803) (Name No. 2513); (b) irritans Linnaeus, 1 758 : 604, as published in the binomen Conops irritans Linnaeus (type-species of Haematobia Lepeletier and Serville, 1828) (Name No. 2514). HISTORY OF THE CASE (Z.N.(S.) 195) This case was first brought to the attention of the Commission in May, 1945 by Dr. A. J. Nicholson of Canberra through Dr. S. A. Neave, the then Director of the Imperial Institute of Entomology (now the Commonwealth Institute of Entomology). The buffalo fly at that time was causing much trouble in Australia where there was disagreement as to its correct name. The species was also an economic problem in America and therefore it was desirable to reach a solution which would have wide acceptance. The case was a complicated one and the situation under the existing Code is not the same as when the case was first presented. Dr. Curtis Sabrosky drew all the threads together in the light of the present Code. His application was received in October 1970, was sent to the printer on 26 October 1970 and was published on 29 March 1971 in Bull. zool. Nomencl. 27 : 234-237. Public Notice of the possible use of the plenary powers in the present case was given in the same part of the Bulletin as well as to seven entomological serials. No comment was received. Bull. zool. Nomencl., Vol. 30, Parts 3/4. June 1974.
