Zhao's diagnosis for the hips and legs of Klamelisaurus included a robust ilium with an indistinct "laminar ridge" and a forward-projecting  (attachment to the pubis); a slender ischium; a robust, thin, flat, and weakly curved pubis (however, this bone appears to be reconstructed); a thick and flat femur with an indistinct head and a  (the attachment for the  muscle) located near the top of the bone; and a tibia shorter than the fibula (however, these bones are either incomplete or heavily reconstructed). Moore and colleagues noted that the anterolateral and anteromedial processes at the top of the tibia formed an acute angle in Klamelisaurus, unlike Bellusaurus where they formed an angle of 80°.
