*71. Alliomma macquarti (Schiner). Synonyms: Tabanus mac- 
quarti Schiner, 1868; Tabanus ruber Macquart, 1845, not of 
Thunberg, 182 7; Tabanus injuscatipennis “Macquart” Surcouf, 
1919, Mesure Arc Equat. Meridien, X, p. 230; Tabanus inde- 
scriptus “Schiner” Krober, 193 le; Gymnochela bigoti Krober,

Boyaca: Muzo (J. Bequaert). — Meta: Restrepo (J. Be- 
quaert; W. H. W. Komp) ; Villavicencio (J. Bequaert). —

Allen). 
The complicated synonymy of this species appears to be as 
follows: (1) Schiner described his T. macquarti from a female 
said to have come from Colombia and his description fits our 
specimens. He gave both T. apicalis Macquart and T. rubidus 
Macquart as doubtful synonyms; but neither of these species 
were Schiner ’s macquarti in our opinion. (2) Macquart gave 
Mexico as the locality of his T. ruber ; but Surcouf (1919) states 
that the specimen at the Paris Museum, presumably the type 
of ruber , bears two labels one in Macquart’s hand “Colombie”; 
the other “Bresil, Guerin-Meneville.” Surcouf redescribed ruber 
from this specimen, for which he also found and published the 
manuscript name injuscatipennis. Our Colombian specimens 
agree with Surcouf s description. (3) Krober described “ Gym- 
nochela bigoti ” evidently from Schiner’s type of T. macquarti , 
although he says that the specimen came from Venezuela. His 
description and figures fit the Colombian specimens which we 
call macquarti. Krober was mistaken, we believe, in referring 
his specimen to T. bigoti Bellardi, which was a substitute name 
for Tabanus apicalis Macquart, 1847 (not of Wiedemann, 
1828), Bellardi’s description being based on Macquarfs type. 
The true bigoti is a Tabanus with a short tooth on the third 
antennal segment, as described by Osten Sacken for the female 
in 1886 (Biol. Centr. Amer., Dipt., I, p. 48). Osten Sacken was 
in error, however, when he cited as a synonym of his bigoti , T. 
macquarti Schiner, which has a very long antennal tooth. The 
true T. bigoti was correctly recognized by Fairchild (1943a, p. 
442, figs. 4 and 5). (4) Tabanus indescriptus “Schiner” is a 
manuscript name which Krober (1931c) found with the type of 
T. macquarti.
