Remarks. This genus resembles Platysympus in the rudimentary exopods on pereopod 2–4 in the female. However, Platysympus lacks the maxillule palp, and has pereopod 5 longer than the basis of pereopod 4, while the new genus has a maxillule palp with two setae and pereopod 5 shorter than pereopod 4 basis. This genus also resembles Doieolamprops in the rudimentary exopod on pereopod 2. However, Doieolamprops has two articles in the uropod endopod and a pair of pleopods in the female, while Paraplatysympus has three articles in the uropod endopod and no pleopods in the female.
