Plate 4 issued from : S. Ali-Khan & J. Ali-Khan in Crustaceana, 1982, 43 (3). [p;269, Figs.27-29]. As Lucicutia polaris.

Nota: 1 small spine present on the outer margin of the 1st exopodal segment of right P5; there is a seta on the outer margin of the 2nd segment of the basipodite of left P5; 3 spines on the 3rd exopodite segment of left P5. Caudal rami 3.7 times longer than wide. A1 reaches to the caudal rami.

Plate 5 Lucicutia polaris female:

Cephalosome with slightly projecting and rounded anterior corners and well developed lateral spinous projections; anal somite about as long as wide; caudal rami 11.7 times longer than wide and bowed outwards at base, leaving elliptical space between rami proximally.
2 - P1 with 2-segmented endopod.
3 - Cephalosome not with 2 pairs of lateral spinous projections, but with other forms.
4 - A1 extending to end of caudal ramus or 1 to 2 segments beyond.
5 - Caudal rami about 10 times longer than wide.

Plate 6 Lucicutia pseudopolaris male:
1 - P1 with 2-segmented endopod;
2 - Caudal rami more than 10 times longer than wide.
3 - Caudal rami 10 to 12 times longer than wide.
4 - Coxa of right P5 similar in length to coxa of left leg; inner margin of coxa of right leg smooth.
5 - Inner distal margin of basis of left P5 with row of spinous processes around inner distal angle and with knob-like process located lateral to end of row.
