Caption:
This illustration depicts a ventral view of two members of the Order Anoplura, i.e., “sucking lice”, the “body louse”, Pediculus humanus var. corporis (Lt), and the “rat louse”, Polyplax spinulosa (Rt). The presence, or absence, and number of sclerotized plates on the abdomen, and the number, size and arrangement of setae on these plates is of great importance in the identification of many species of lice. Note the location, and shapes of the sternal, tergal, and paratergal plates, as well as the setae on the abdominal exoskeletal surface.
