Bibio Fabricius, 1775

Michelsen, Verner & O’Hara, James E., 2014, A review of genus-group names in Diptera (Insecta) that J. C. Fabricius “ borrowed ” from other dipterists and proposed as new in his systematic works from 1775 to 1805, Zootaxa 3873 (1), pp. 73-81 : 74

Bibio Fabricius, 1775 : [31], 756.

Type species: Musca plebeja Linnaeus, 1758 (the 4th of 14 originally included species), by present designation. Junior homonym of Bibio Geoffroy, 1762 . Objective synonym of Thereva Latreille, 1797 (see below), syn. n. ( Therevidae ).

Remarks. The name Bibio Geoffroy, 1762 , originally proposed mainly for species of Bibionidae , was cited under Tipula hortulana Linnaeus by Fabricius (1775: 754, 1794: 248). In the same work Fabricius (1775) made his own proposal of the name Bibio for 14 species belonging to the families Bombyliidae (8), Therevidae (4), Mydidae (1) and Stratiomyidae (1). Fabricius (1805) later refined his concept of Bibio to consist of 10 Therevidae and 1 species each of the families Athericidae , Phoridae and Syrphidae . Fabricius’s usage of Bibio for therevid flies became widely accepted in the pre-1815 literature (J.W. Meigen, C.F. Fallén, etc.), but was later replaced by the name Thereva Latreille, 1797 . The type species of Thereva Latreille, 1797 was designated by the International Commission on Zoological Nomenclature (2006: 72) as Musca plebeja Linnaeus, 1758 under their Plenary Powers. The present fixation of a type species for Bibio Fabricius, 1775 places at long last this name into formal (and objective) synonymy with Thereva Latreille. Incidentally , the International Commission on Zoological Nomenclature (1957: 88) placed Bibio Fabricius, 1775 on the Official Index of Rejected and Invalid Generic Names in Zoology (Name No. 841).
