If I remember correctly the names Super and Eternal are not used for the inner and outer senshi, only Moon carries those names, anyway, it's implicit that their uniforms are very similar to Sailor Moon's so they can be called Super and Eternal too.
This
scan was what I was talking about.
It calls the eternal-style Sailor Chibi Moon, Super Sailor Chibi Moon (スーパーセーラちびムーン), although they do leave out anything for the other Sailor Senshi. It dosen't really make much sense though
.
Although I clearly remember in the Anime they were identified as Super Sailor Senshi (as well as in the games).
