Yugoloths > anything else
No, I think you've got all of the unconverted ones listed there. Unless you wanted to include the Nalg, a NE impish type fiend used as familiars sometimes. However as far as I know, aside from an appearance in a very early dragon mag issue, it hasn't shown up since, and it was never referred to as, or connected to the yugoloths. I've used it in my own material as a created yugoloth servitor race, much like the guardian yugoloths.
There's also the handful of unique yugoloths, both altraloths(hag empowered) and not.
And, having said that, seeing the Baernaloths in print, one way or another, would be very cool. I've been writing a series of 13 stories based on them lately, one story per individual Baern (The specific Baernaloths of 'The Demented', the ones mentioned in 'Planes of Conflict'), three of them written so far, and trust me I go with the flavor and legend behind them and give them power accordingly. CR 9? *snort*

I'll have the 4th of the series, 'The Blind Clockmaker' out sometime this week I figure.
