The classification and distribution of tananidae (Diptera) 2. History: Morphology: Classification: Subfamily Pangoniinae.

Abstract

Classifications proposed in the past are reviewed, the male and female genitalia described in some detail, and the relationships which they indicate found to agree with those suggested by the known larvae and pupae. Parallel evidence from external characters of the adults is partly obscured by convergent evolution between the subfamilies. Pelecorhynchus, Bequaertomyia, and Heterostomus are excluded from the Tabanidae. The genera of Pangoniinae are defined. The following cannot be placed from descriptions: Palaearctic - Scaptiella End. ; spp. described as Corizoneura. Nearctic - Zophina Philip. Neotropical- Leptofidena Krob. The suggested arrangement of the remaining genera is as follows, those placed tentatively from descriptions being indicated by an interrogation mark. PANGONIINI Palaearctic - Pangonius Latr., with possible subgenera Pangonius Latr., Tanyglossa Mg., and ?Ectinocerella Seg. Nearctic-Esenbeckia Rond.; Apatolestes Will.; Brennania Philip; Pilimas Bren.; Stonemyia Bren.; Asaphomyia Stone. Neotropical- Esenbeckia Rond.; Proboscoides Phil.; Chaetopalpus Phil.; Protodasyapha End.; ?Histriosilvius Krob.; ?Protosilvius End. Australasian - Austroplex, gen. nov. (type goldfinchi, sp. nov.) ; Ectenopsis Macq., with subgenera Ectenopsis Macq., Leptonopsis, subgen. nov. (type vittata, sp. nov.), Parasilvius Ferg., and Paranopsis, subgen. nov. (type lutulentus Hut.); Caenoprosopon Ric.; Therevopangonia, gen. nov. (type insolita, sp. nov.). SCIONINI Nearctic - Goniops Aldr. Neotropical - Mycteromyia Phil.; Pityocera G.-T.; Elaphella Bezzi; Scione Walk.; Fidena Walk.; Scaptia Walk., with subgenera Scaptia Walk., Pseudoscione Lutz et al., and'Pseudomelpia End. Ethiopian - Scaptia Walk., subgenus Pseudoscione only.* Australasian -Australia : Scaptia Walk., with subgenera Scaptia, Pseudoscione, Myioscaptia, subgen. nov.
