Diagnosis. Laophontidae : Paralaophonte . Female antennule six-segmented; male antennule subchirocer; second antennulary segment with spinous process or a small blunt conical protuberance. Mandibular palp one-segment- ed (basis, exopod and endopod fused). Maxilliped subchelate; relative position of the maxilliped ventral. P1 EXP two-segmented; P1 ENP two-segmented, first segment elongate, longer than second segment, the latter with strong claw and small slender seta; P2–P4 EXP three-segmented; P2–P3 ENP two-segmented; P4 ENP one-segmented. P5 EXP and baseoendopod separated in both sexes, outer basal seta arising from well-developed setophore; female P5 EXP oblique. Armature formula of P1–P5 as follows:

Genital and third urosomites fused in female forming genital double-somite. Caudal rami cylindrical, with seven setae, caudal setae IV and V whip-like.

Sexual dimorphism expressed in antennule, P2 ENP2 (subdistal inner seta of ENP2 thickened, with lamellar outgrowths in distal third), P3 EXP (expressed in stronger segments and outer spines), P5, and P6.
