Anatomy The anatomy of this subfamily is defined by the presence of a diverticulum and three to four dart apparatuses (the love dart is used in mating behaviour). They always have the same number of dart sacs and mucous glands, with two darts per dart sac. The mucous glands are situated on, and open into, the vagina, above the dart sac.
