Details of genital structures of mated L. geometricus females in different developmental stages. Dorsal is at the top, ventral is at the bottom. a-c: Right copulatory duct and right spermatheca of a mated late subadult female. The spermatheca is completely filled with spermatozoa that are imbedded in a red-pink secretion. c: The male embolus tip (plug) is located inside the spermathecal entrance (arrow). d-f: Right copulatory duct and right spermatheca of a mated adult female. e: The spermatheca is filled with spermatozoa that are imbedded in a red-pink secretion. f: The male embolus tip (plug) is located inside the spermathecal entrance (arrow). Scale bars = 50 μm. cd, copulatory duct; e, epithelium; s, spermatozoa; se, secretion; sp., spermatheca; spc, spermathecal cuticle
