Its headshield (or cephalon) is semi-circular to rectangular with rounded frontal corners. It lacks eyes, but eye ridges are present. The fact that the facial sutures are opisthoparian (with sutures in Pliomera gonatoparian) is an exception in the otherwise proparian Cheirurina. The thorax has 11 or 12 segments, with the axis slightly wider than the ribs (or pleurae) to its sides. The tips of the pleurae are free, which resembles an old-fashion central heating radiator. The axis in the small tailshield (or pygidium) consists of four
