Diagnosis
The four subfamilies of Halocyprididae can be distinguished on the basis of the numbers of terminal setae on the first antennae and the presence or absence of a processus mamillaris on the endopodite of the second antenna.
The Conchoecinae have 5 terminal setae on the first antennae and a processus mamillaris on the endopodite of the second antennae (female, 2nd antenna, male endopodite of 2nd antenna). Halocyprinae also have 5 terminal setae on the first antennae but lack a processus mamillaris. Archiconchoecinae have 6 subequal terminal setae and no processus mamillaris, whereas the Euconchoecinae have >20 terminal setae and no processus mamillaris.
