Tabanidae of Colombia 
115. Tabanus (Lophotabanus) pseudoculus Fairchild, 1942. 
Boyaca (? or Caldas) : Neira (L. Murillo. — Determined by 
G. Fairchild). — Not seen by us from Colombia. 
*116. Tabanus (Lophotabanus) xipe Krober, 1934. Synonym: 
Lophotabanus surinamensis Krober, 1929; not Tabanus surina- 
mensis Macquart, 1838. 
Choco: Andagoya (A. Gast). — Meta: Restrepo (J. Be- 
quaert; also reported by Antunes, 1937); Villavicencio (M. 
Bates). 
117. Tabanus (Lophotabanus) oculus Walker, 1848. Synonyms: 
Tabanus albo-notatus Bellardi, 1859; Tabanus oculatus Dunn, 
1929 (misspelling of oculus ). 
Santander Sur: Jazmin, between Puerto Wilches and Bu- 
caramanga (reported by Dunn, 1929). — T. oculus was origi- 
nally described in part from Colombia without more definite 
locality. — -Not seen by us from Colombia. 
After studying many specimens of this group from Yucatan, 
Honduras, Guatemala, Panama, Colombia, Venezuela, Trini- 
dad, and Brazil, we have come to the conclusion that T. albo- 
circulus Hine and T. xipe Krober will eventually be synony- 
mized with T. oculus. T. oculus is used at present for speci- 
mens with the first posterior cell closed and stalked before the 
margin, a character which is not always of specific value in 
Tabanus. 1 Of the others, with open first posterior cell, the 
larger specimens are placed in xipe , while the smaller ones be- 
come albocirculus , a procedure which leaves the medium-sized 
ones in doubt. Specimens with the first posterior cell closed 
just at or near the margin, or barely open, must also be placed 
arbitrarily. 
*118. Tabanus (Lophotabanus) pruinicorpus Krober, 1934. Syn- 
onym: Lophotabanus pruinosus Krober, 1929; not Tabanus 
pruinosus Bigot, 1892. 
Magdalena: Rio Frio (G. Salt); Sevilla (G. Salt). — Kro- 
ber originally described his L. pruinosus from Bolivia and Co- 
lombia (supposedly from Bogota, a locality which is perhaps 
open to question). 
1 In the present paper the subgenus Lophotabanus Szilady (1926) includes 
Bellardia Rondani (1864) (not of Robineau-Desvoidy, 1863), a name later 
changed to Bellaria Strand (1928).
