Genital double-somite with variable length: width characteristics, widest width, in dorsal view at variable positions anterior to posterior. Pedigerous somite 5 posterolateral corners of variable shape. Female antennule ancestral segment XXIII with aesthetasc, spines may be present along anterior and posterior borders of some segments in some species; female and male ancestral segments I, II, III, and V with dorsal surface hair sensillum, usually with adjacent macula cribrosa. Right male antennule segments XIV–XV and XXI–XXIII fused, segments XIX, XX, XXI and sometimes XVIII with fused gripping elements. Antennal exopod ancestral segments I–III with vestigial seta, seta on segment IV extends short of distal border of exopod. Mandibular gnathobase with ventral tooth set at right angles to main plane of gnathobase therefore appearing tapering, similar to other teeth; endopod segment 1 with 4 setae (distal seta very small), endopod segment 2 with 9 long setae and 2 vestigial setae. Maxillulary setation species specific. Setae of maxilla endopod curled completely in on themselves and with row of fine, long dense setules along distal half of concave surface; long setae extending anteriorly beyond rostrum, inner proximal seta of endopod segment 2 vestigial.
