Etymology

Solem chose the generic name Ba after Ba District, Fiji, which extends into B. humbugi’s range. This led to him having an “irresistible impulse” to name the type species Ba humbugi,[4] in reference to the character Ebenezer Scrooge’s catchphrase “Bah! Humbug!” from Charles Dickens’s novella A Christmas Carol. One review of Solem’s monograph naming this species said his choice in taxa names “may either lighten the reader’s day or engender hostility”

I for myself think that the abbrev. from Ba to B. really helps. :)
