NO. 3 NEOTROPICAL FLIES, TABANIDAE — FAIRCHILD 27 



*rnbidiis Macq. 1847, Dipt. Exot., Suppl. 2: 19. (Tabanus) B. M. Not T. rti- 

 bidiis Wied. 1821. Krober (1934) as T. rubricosa, nom. nov. Not T. rubri- 

 cosa Wulp. 1881. Type headless and excessively dirty, probably now inde- 

 terminable. Near *fallax Macq. and albibarbis Wied. 



*rubiginipennis Alacq. 1845, Dipt. Exot., Suppl. 1:39. (Tabanus) B. M.(H) 

 1= *Tabanus adustus Wlk. 1850. Krober (1940) as Didadocera. Bequaert 

 and Renjifo (1946) as Hybomitra. Eyes bare, subepaulet setose. Near 

 bigoti Bell. 



*rubiginosa Summers 1911, Ann. Mag. Nat. Hist., ser. 8, 7:213. (Dichelacera) 

 B. M. = (Psalidia). Krober (1934) as Dichelacera. Close to fidminca 

 Hine, but with bicolored fore tibiae and widely open cell R5. 



*rubribarbis Big. 1892, 5:630. (Atylotiis) B. M.(H) = Dichelacera (Psa- 

 lidia) furcata (Wied.) 1828, Krober (1932b). 



*rubrinotatiis Big. 1892, 5:676. (Atylotus) B. M.(H) = *Tabanus guyanen- 

 sis Macq. 1845. Krober (1934) does not mention. (N.S.) 



*rubripes Macq. 1838, Dipt. Exot., 1(1): 138. (Tabanus) M. P.(H). The 

 type is labeled "Sylveira Bresil 1832" though the original description says 

 "Cayenne, Sylveira." All other Sylveira material was from Brazil, so I be- 

 lieve Macquart erred here in transcribing the locality. Krober (1930c, 1934) 

 as (Macrocormus). The species is close to sorbillans, but distinct. Speci- 

 mens in B. M. det. Bigot are sorbillans Wied. 



*rubrithorax Macq. 1838, Dipt. Exot., 1(1): 143. (Tabanus) M. P.(H) = 

 Stenotabanus. Type headless, but appears to belong in group of pequeniensis 

 Fchld. with a few setae on subepaulet. 



*rubriventris Krob. 1930, Mitt. Mus. Hamburg, 44:165. (Osca) B. M. = 

 Scaptia. 



*rufa Macq. 1847, Dipt. Exot., Suppl. 2: 13. (Dichelacera) B. M. = ? Dichela- 

 cera stibmaryinata Lutz 1915. Rondani (1850) transfers to Tabanus and 

 changes name to brasiliensis, nom. nov. Lutz (1907) := ? D. januarii var. 

 Krober (1934) ■= januarii Wied. A pale form with reduced wing markings 

 and broad frons. 



*nifescens Ric. 1900, Ann. Mag. Nat. Hist., ser. 7, 6:294. (Erephrosis) 

 B. M.(H). The holotype is in Budapest; this is a paralype. = *Scione 

 aureopygia Fchld. 1942. = *Fidcna fulvosericea Krob. 



*ruficornis Krob. 1931, Stett. Ent. Zeitg., 92:287. (Tabanus (Agelanius)) 

 B. M. = Tabanus erythrocerus Krob. 1934, nom. nov. Not T. ruficornis Fab. 

 Subepaulet setose. Close to *desertus Wlk. and *johannesi Fchld. 



♦rufipennis Macq. 1838, Dipt. Exot., 1(1) : 138. (Tabanus) M. P. = Didado- 

 cera. Subepaulet bare, labella with sclerotized plate. Very close to *castanea 

 Big. and unicolor Lutz, and all may be variants of same species. *Satanica 

 Big. also close, but distinct. 



♦rufipes Macq. 1850, Dipt. Exot., Suppl. 4:37. (Silvius) M. P. = ? Veprius. 

 Type very dirty, 9-10 mm. Hind tibial spurs and ocelli present. Proboscis 

 short and fleshy. Frons wider than high, divergent, callus transverse, barlike. 

 Third antennal segment with a basal plate and probably four annuli. 



♦rufithorax Wlk. 1848, List, 1:165. (Tabanus) B. M. == Catachlorops, 

 Krober (1934). Barretto (1946) in key only. 



*rufivcntris Macq. 1838, Dipt. Exot., 1(1) : 145. (Tabanus) B. M. = *Tabanus 

 bifloccus Hine 1925. Not T. rufiventris Fab. 1805 or Macquart 1845. Krober 

 (1934) does not list. Bequaert (1940) = ? T. hookeri Knab.
