Coupling of the genitalia

The claspers and other grasping devices of the male grasp the terminal end of the female abdomen to establish the coupling of the genitalia (Figs 4, 5). The hypovalves with incrassate processes seize the female cerci and cause the cerci to bend dorsad (Figs 4, 5a, b). The finger-like basal processes of the male gonostyli clasp the rotated genital segments of the female (Figs 4a, 5b, d). The paired lobe-like basal teeth seize the rear area of the genital chamber (Figs 4b, 5c).
