Figure 6

Specialised integumentary structures on the prothoracic leg of Theristria delicatula (Mantispidae: Drepanicinae; extant). (a) Lateral (ectal) view of the right prothoracic leg (specimen 1). Arrow points to the tip of the major IP. (b) Lateral view of the distal half of a femur showing diversity of spine-like integumentary specialisations (specimen 2), including three major IPs each bearing a partly invaginated chitinous cone (Stitz organ) (right inset), minor IPs bearing modified setae with length ratio between the two of ca. 1:1 (left inset, right), and spine-like setae inserted on a subglobular base (left inset, left). (c) Lateral view of the ventrodistal part of the tibia, showing row of prostrate setae, with inset on two distalmost prostrate setae (specimen 1). (d) Lateral view of ventral side of foretarsomeres 5 (left) and 4 (right), with inset showing the basalmost prostrate setae (specimen 2). (e) Ventral view of a foretarsus (specimen 2).
