Figure 8

Shapes of the labial segments of the Nepidae (Ranatrinae). (a)-(b) Cercotmetus asiaticus. (a) Dorsal view (D) of the labium, the II, III and IV segments are visible, the articulation of the dorsal condyle (cd) between the II and III segments on the dorsal side, intercalary sclerites (is) on the III segment, the stylet groove (gr) is partly opened at the base of the second segment, only the remaining segment of the stylet groove is closed. (b) Ventral view (V), shape of the first segment is slightly visible with the midventral condyle (cv), the base of the second (II) segment in narrower than the end of the first (I) segment, the distal margin is wide, the connection between the third and fourth segment with the midventral condyle (cv) on the distal edge of the third segment, on the IV segment the oval apical plate is visible. Mxp: maxillary plates.
