Dont know if this will help, but check link below:
Florida Museum of Natural History Ichthyology Department: Gag Grouper
Taxonomy
This grouper was first described as Trisotropis microlepis by Goode and Bean in 1879. However, this name was later changed by taxonomists to the currently valid Mycteroperca microlepis (Goode and Bean, 1879). The genus name, Mycteroperca, is derived from the Greek, "mykter, -eros" meaning nose and "perke" meaning perch. The species name, microlepis, is derived from the Greek "micro" small and "lepis" meaning scale, in reference to the small scales covering the body of this fish.
Some folks tend to believe that gag's and black groupah's are the same... I was always under the impression that they are two different animals.
Either way,, to me,, a groupah is a groupah! they eat the same, fight the same.. and dang near look the same... so calling a black groupah a gag or vice versa... doesnt matter, it's a groupah and a fine eatin fish!
These are pic sof a black groupah's:
