Hemming (1967) stated:-

The name Flaccilla Godman was formerly considered to be invalid as a junior homonym of Flacilla Koken, 1896 (JahrB. geol. ReichsAnst. 46 : 92), and, as such, was replaced in 1939 by Aecas Hemming. However, under a provision adopted by the Copenhagen Congress in 1953 and now embodied in the revised Code in Article 56 (a) a one-letter difference in spelling serves to prevent any two generic names from being treated as homonyms of one another. Under this provision, therefore, the name Flaccilla Godman is a homonym of Flacilla Koken, but is an available name.
