The phallus originates on the ventral side of the abdomen between the epandrium and hypandrium. It usually is long and slender (except in species of the daciformis and dentata groups), and at rest the apical part is coiled and placed between tergite 5 and the rest of the male terminalia. The glans is the expanded, apical part of the phallus, which must be extended to observe the glans.
