Fig. 5From: Functional morphology of immature mating in a widow spiderSperm transfer and storage sites of virgin L. geometricus females in different developmental stages. Dorsal is at the top, ventral is at the bottom. a-b: Right copulatory duct and right spermatheca of an early-subadult female. Both structures are filled with a light blue secretion. c-d: Right copulatory duct and right spermatheca of a late-subadult female. Both structures are filled with a light blue secretion. e-f: Right copulatory duct and right spermatheca of an adult female. Both structures are filled with a bright blue secretion. Scale bars = 50 μm. cd, copulatory duct; e, epithelium; se, secretion; sp., spermatheca; spc, spermathecal cuticleBack to article page
