Kitrap's appearance seems to have an inconsistency. In his first appearance in D'Argo's Lament, Part 1, he appeared to be a darkly complexioned alien of a different species than any that have appeared in Farscape. His later appearance in Part 3 showed him to be a Ytrehoddish much like the other beings on Egrof. It's possible that one of the beings claiming to be Kitrap were merely one of his lieutenants or it could be artist error.
