indios tepostli de Jocotepec, Jalisco

While reading through entries in Jalisco, 1700-1750's, mostly from Jocotepec, I came across references to individuals who were indios tepostli / telpostle / tepustli, a word new to me. I assume they were nahua people? Can anyone on the forum tell me the correct designation, or share any information about them with us? Thank you.
