Occurrence of Spermatophores in the Genus Dolops (Crustacea: Branchiura)


ACCORDING to all those who have defined the group, one of the diagnostic characteristics of the Branchiura is the absence of spermatophores. Indeed, the mating habits of members of the genus Argulus are sufficiently well known to enable it to be stated that here no such structures are involved in sperm transfer, and recent unpublished observations on various species of the genus Chonopeltis (some as yet undescribed) indicate that here also no such structures are found. On the other hand, the existence of spermatophores in the genus Dolops has recently been established.
