Ok, what do they look like?
Baboons: Like normal baboons, but larger and more upright. They are intelligent and can speak. They use spears, rarely wear armour, have fur and brightly coloured backsides which they flash at every opportunity. In RQ2/3 they worshipped Grandfather Baboon, who is their ancestral god, Hunter and various unspecified spirit cults.
Morokanth: The classic explanation is that they are like large, intelligent tapirs. Have you seen the TV programme "ALF"? Way back in the eighties, he was an Alien Life Form who lived with an American family. Well, ALF, or Gordon Shumway, looks like a Morokanth, except that he is too small. Make him bigger than human sized, a bit darker, cut his thumbs off and you get a morokanth. They worship the Praxian deities and herd unintelligent Herd Men which they eat.

Telmori: These are werewolves, well they aren't really. They are human and look human, but they might have bushy hair, bushy eyebrows and be a bit snarly. They worship Telmor the wolf god and have magic that enables them to turn into wolves. Wolfbrothers are Werebeasts, humans that can turn into woves, who normally worship Telmor or are part of Telmori clans. They look like Telmori, but I always play that their eyebrows join in the middle, a dead giveaway, unless the shave the middle of the eyebrow off, sneaky buggers. They have to change into wolf form every full moon, which in Glorantha is once a week.
Wind Children: These are easy. They are winged humanoids, imagine the classic angel or the Hawkmen from Flash Gordon, but a bit wimpier. They live on high mountaintops, don't wear a lot of armour, use slings and rapiers, worship Storm Gods and can control Sylphs (Air Elementals) naturally.
Grotaron: Maidstone Archers and possibly the silliest Gloranthan species. No head, their mouth is in their chest, they have three arms and have an eye in the palm of each hand. They are giants and wield a gigantic bow which they hold in two arms and draw with the third, and use three mauls in combat, hence the windmill effect.
If you do a Google search for Grotaron you get a lot of pictures of Kalikos, the Finnish RQ Society, but they don't look THAT bad, really.
I can't find any online pictures of the others, unfortunately.
Mr Qwiki has the Monsters SRD in PDF Form and that should have some of these in. The link is

Hope that helps.
Have you got the Monsters book? It has loads of ideas in. If not, the SRD is pretty much just as good.
