). The use of spermatophores to transfer sperm from the male duct to the spermatheca, instead of a more typical mating behavior involving a direct sperm transfer by opposition of male and spermathecal pores, suggests an unusual mating behavior and a specific function of the spermatophores (see discussion).

The rare occurrence of sperm transfer through spermatophores in microdriles contrasts with its common occurrence in rhynchobdellid leeches. Evolutionary derivation of leeches from a lumbriculid-like ancestor had been suggested by several phylogenetic studies based on morphological characters (Brinkhurst & Nemec 1987;
