(a)Spermatophore transfer tube still within the vaginal pouch; (b) evagination of the spermatophore transfer tube; (c) procurement of the spermatophore, spermatophore transfer tube inserted into the spermatophore transfer tube; (e) acquisition of the spermatophore into the vginal pouch by the invaginating spermatophore transfer tube

• Alignment of mating pairs during spermatophore exchange: (a) individuals aligned head-to-head with non-simultaneous acquisition of spermatophores (note acquired spermatophore within vaginal pouch); (b) simultaneous reciprocal acquisition of spermatophores of individuals aligned head-to-head; (c) individuals aligned head-to-head with simultaneous acquisition of spermatophores (note: spermatophore still within spermatophore chamber): (d) individuals aligned head-to-haptor with simultaneous exchange of spermatophores
