Specialised integumentary structures on the prothoracic legs of extant and extinct mantispoids. (a) Anchieta notha (Mantispidae: Symphrasinae; extant), lateral view of forefemur. (b) Same specimen, detail of the basal part of forefemur in lateral view, showing a spine-like seta with a globulose base of insertion (arrow) and two IPs, i.e., a small conical process (left inset) and the basalmost (major) process (right inset), each bearing a chitinous cone (Stitz organ). (c) Nolima victor, syntype (Mantispidae: Calomantispinae; extant). Lateral view of forefemur, foretibia, and foretarsus, with an inset of minor forefemoral IPs bearing chitinous cones (Stitz organs) (top inset) and row of prostrate setae on foretibia (bottom left inset) and foretarsus (bottom right inset). (d) Eorhachiberotha burmitica, holotype (Rhachiberothidae: Paraberothinae; extinct). Lateral view of the forefemora and foretibia. Arrow points at the insertion of a modified seta on the basalmost forefemoral IP.
