copulatory male
A fully adult male. In the janiroidea isopods, the male is identified by a sperm tube on the second pleopod's stylet, which is open at its sharp distal tip. In some specimens at this terminal stage, the vas deferens is visible through the cuticle connecting to the penile papilla [Wilson, 1989].
