As with several other cast members, I have not found a great deal of information on Mr. Thelman.

At this time, it appears that he was a regular ensemble member for Amando De Ossorio, and is quite possible that he served the director in other capacities behind the scenes.  I will add more information as it becomes available to me.

His role in "Night of the Sorcerers" is rather sinister, first appearing to the group as a friendly stranger, there to warn them of the danger in camping where they are.  He offers his services as a guide, which they accept, but soon shows his true motives as he viciously assaults one of the female party members.  He has underestimated the powers of Tunika, however, as she retains her strength even after enduring his brutal attack, and shows him who is truly in control.
