Taxonomic notes

This species was described by Smith in 1931.1
This was originally described as Ephalophis greyi1, but subsequent work by Glenn Shea2 showed that the B. Grey after which the species was named was in fact a Mrs Beatrice Grey, generally accepted as being a woman. The species' name was then amended to the feminine E. greyae, but I think this is against ICZN rules. I should probably look into this in more depth, rather than writing wild speculation like this.
