Bubacua, new genus, is similar in many features to Hortensia Metcalf and 
Bruner, as these authors stated in the original description of the type-species. 
The venation of the forewing is like that of Hortensia. But vestigial paraphyses 
are present, the ocelli are closer to the median line than to the adjacent an- 
terior eye angle, the clypeus is flattened, the width of the pronotum exceeds 
the transocular width of the crown; the male pygofer is not produced acutely, 
and all of these features differ from Hortensia. Also the distinct veins of the 
forewing and the partly (at least) pale crossveins differ from Hortensia. The 
female genital structures suggest a close relationship to Cubrasa, new genus. 
Bubacua, new genus, is known only from the type-species, which occurs in 
Cuba. My interpretation of this species is based on a study of the type-series, 
including the holotype.
