Bomhylomorpha Lutz 1911a, p, 33, with erythronotata Big., pseudo - 
analis n. sp., analis Fab. and leonina n. sp. Type erythronotata 
Bigot (Borgmeier 1933). 
Bombylomyia Lutz 1911b, p. 69 with B. splendens n. sp. descr. 
Bombylopsis changed to Bombylomyia. 1914a with nitens Big. 
The status of these names is confusing. Bombylomorpha and 
Bombylomyia may have been created to replace Bombylopsis , 
thought to be preoccupied. I have been unable to find that this 
name is preoccupied and Lutz and Castro 1936 have reverted 
to its use. The selection of erythronotata Big. as type of Bom- 
bylopsis is incorrect, as it was not included in the original pub- 
lication. The only species available as genotype for Bombylop- 
sis is nitens Bigot 1892 and it is here selected. Since both 
Bombylomyia and Bombylomorpha were substitute names, they 
take the same genotype. Ionopis or Ionopsis (q.v.) will fall 
as a synonym, as it has the same genotype. There is no need 
to replace the latter name until it becomes clear that the con- 
cept it was intended to cover is needed.
