a, b: Cleared epigynum with paired spermathecae and copulatory ducts of mated L. geometricus females, showing different plug types and plug positions. Dorsal view. Anterior is at the top, posterior at the bottom. a: Female genitalia containing an embolus tip in each spermatheca (arrows). Emboli are located at the spermathecal entrance and extending to the most anterior inner wall. b: Female genitalia containing male plugs that are located inside the copulatory duct, showing an embolus tip on the left side (arrow) and a whole embolus on the right side. c, d: Different states of the sperm transfer organ (emboli) on the male pedipalp after mating. Ventral view. c: Embolus with intact tip. Arrow points to the thickened breaking point. d: Embolus missing the tip (arrow). Scale bars = 0.1 mm
