Coupling of the male and female copulatory organs in adult mating after copulatory somersault (a, b, c), in adult mating prior to somersault (d, e, f) and in immature mating (g, h, i) in L. geometricus. While the position of the cymbium and haematodocha slightly differed between cryofixed pairs, the apophyses and the embolus are locked in the same manner in all three positions/groups. The haematodocha is depicted as transparent because of its membranous nature
