Armature formula of swimming legs P1 to P4.

Nota :
- P5 absent in female.
- Male P5 large, well developed, asymmetrical ; right leg with 2-segmented exopod and styliform ; 1-segmented endopod. Distal exopodal segment elongate, often styliform. Left leg with 2-segmented exopod and small distal process on elongate basis representing endopod. Distal exopodal segment with complex armature typically consisting of serrated lamella, ridged digitiform process, hirsute lobe and movable finger ornamented with row of setules near tip ; movable finger drawn out to form long spiniform process in some species.
- Eggs retained in mass on ventral side of urosome . Nauplii lecihotrophic.
