Armature formula of swimming legs P1 to P4.
Nota: Endopod of P4 on right side modified in Parastephos: middle endopodal segment elongate, distal segment with strong spinules on surface and with proximal seta on inner margin slender, denticulated and spiniform.
- Female P5 minute ; with coxae and intercoxal sclerite fused to form transverse coxal plate ; each leg tipically uniramous, comprosing basis and single tapering rxopodal process ; basis and process often fused ; process usually ornamented with spinule rows or teeth.
- Male P5 powerfully developed and strongly asymmetrical ; right leg slender, uniramous, 4 to 8-segmented, terminal segment often tapering, spiniform ; left leg uniramous, tipically 5-segmented with 4th segment robust and swollen, distal segment variable in form, often spoon-like ; both 4th and 5th segments often with additional processes ; right leg reduced to 2-segmented rudiment in Miostephos
- Eggs released into waters.
